Technical field:

The invention relates to a glove and a preparation method thereof, in particular to a fluorine/nitrile rubber compound glove and a preparation method thereof, which belongs to the technical field of labor protection products.

Background technology:

Gloves are the most important and commonly used labor protection products in People's Daily production and manufacturing. The existing gloves are cut and sewn with various leather, knitted fabric or woven fabric.Knitted gloves are made of pure or blended yarns of various textile fibers, which are woven on the glove machine and processed by sewing, such as lining, rims, fingertip and finger fork, etc., and then processed by pulling or flexing and heat setting finishing.Knitting gloves have flat needle, rib, ring, leno and other organizations, patterns have plain and yarn-dyed jacquard.And labor protection glove requirements are relatively thick, to pass the surface treatment, in order to improve wear resistance, acid resistance, chemical resistance and other properties.At present, the surface treatment materials used in the market mainly include PVC(polyvinyl chloride), PU(polyurethane), NR(natural rubber), NBR(nitrile butadiene rubber), CR(neoprene) and so on.Because of NBR has both high puncture resistance, tear resistance, higher comfort and dexterity, and good chemical resistance, so the gloves nitrile rubber surface treatment is widely used in automation, aviation, printing, chemical, oil, electric wire and cable, and other fields, but high temperature resistant performance of nitrile rubber co., LTD., generally can reach 120 ° C, and meet oxygen such as prone to oxygen and chapping, and in corrosion resistance, poor resistance to acid, alkali, etc.It is necessary to use higher performance materials for surface treatment, such as fluororubber materials. Fluororubber materials have high temperature and corrosion resistance, so they have good corrosion resistance for most inorganic acids, hydrocarbons, chlorides and aromatic solvents.But fluorine rubber is expensive, high cost, and poor processing performance also limits its universal application to some extent.

The invention content

The invention provides a fluorine/nitrile butadiene rubber composite glove with low cost, which is resistant to acid, alkali and chemicals.The purpose of the invention is to implement a fluoro/NBR composite glove sleeve by the following technical scheme, including a fiber glove lining, on which a nitrile latex layer is coated and a fluoro rubber layer is coated.The invention adopts fiber materials as glove lining, especially composite fiber as glove lining. The fiber materials can be cotton, hemp, bamboo and other plant fibers, or synthetic fibers such as nylon, dacron and acrylic fiber.This invention adopts the fluorine rubber and nitrile rubber coated in fiber lining gloves are a combination of two kinds of rubber made from the surface of their respective advantages, it has realized the NBR benzene, xylene and other chemical resistance, and good of fluorine rubber were resistant to strong acid, strong alkali, high temperature and corrosion resistance, more superior performance than the existing general gloves, and lower cost.Fluoro rubber particles are sprayed on the surface of the fluoro rubber layer in the fluoro/NBR composite gloves.The fluoro rubber layer is sprayed with fluoro rubber ion on the surface of the glove.

Right to ask

A fluoro/nitrile rubber composite glove, including a fiber glove lining, is characterized by a nitrile latex coating on the surface of the fiber glove lining and a fluoro rubber coating on the surface of the nitrile latex coating.

2. According to the fluorine/nitrile rubber composite glove mentioned in claim 1, the feature is that the fluororubber layer is sprayed with fluororubber particles.

3. According to the fluoro/NBR composite gloves mentioned in claim 1 or 2, the characteristics of the NBR latex layer are that the NBR latex layer is coated on the lining surface of the fiber gloves by means of slurry dipping.1 to 5 copies of vulcanizing agent;Activator 2-6 parts.

4. According to the fluoro/NBR composite gloves mentioned in claim 1 or 2, the fluoro rubber layer is coated on the surface of the NBR latex layer by the way of spraying, and the fluoro rubber slurry includes 100 fluoro rubber parts of the following weight;1 to 5 copies of vulcanizing agent;1 to 3 parts of vulcanization accelerator;50 to 200 esters.

5. A preparation method of fluoro/NBR composite gloves, which includes the following steps: a, preparation of NBR latex with 100 parts by weight, 1-5 parts by vulcanization agent and 0.5-3 parts by activator;According to the weight of fluororubber 100 parts, dispersive fluororubber vulcanizing assistant 2-8 parts dissolved in 50-200 parts ester solvent to prepare fluororubber glue.B. Dip the fiber glove lining into the assembly line mold after surface treatment, immerse it into the nitrile butyrate latex prepared above, vulcanize it for 20-40 minutes at 100-150°C, and then dry it for 20-40 minutes at 80-120°C.C. Gelatinize the raw glove after drying in step b, and then spray the prepared fluororubber gel with fluororubber particles. Vulcanize for 5-30 minutes at a temperature of 160-200°C;Dry for 40-100 minutes at 80_160°C, de-mold cold.

6. According to the preparation method of fluorine/nitrile butadiene rubber composite gloves mentioned in claim 5, the characteristic is that in step b, the curing temperature is 120°C, the curing time is 30 minutes, the drying temperature is 100°C, and the drying time is 30 minutes.

7. According to claim 5 or 6 of the preparation methods of the fluorine/NBR composite gloves, its characteristic lies in step c vulcanizing temperature of 180 ° c, vulcanization time for 10 to 20 minutes, drying divided into three stages, the first stage in the temperature of 80 ° c, drying 20 to 30 minutes, the second phase in the temperature is 110-150 ° c, drying 20 to 30 minutes, the third phase in the temperature of 160 ° c, drying 20 to 30 minutes.

The full paper

The invention relates to a fluorine/nitrile rubber composite glove and a preparation method thereof, which belongs to the technical field of labor protection products.The glove including fiber lining in fibers have nitrile latex glove liner surface coating layer, the nitrile latex layer surface coated with fluorine rubber, the fluorine rubber, fluorine rubber particles on the layer are spraying, including nitrile latex layer composed of NBR, curing agent, activator components, such as fluorine rubber latex by fluorine rubber, vulcanizing agent, vulcanization accelerator, esters of solvents and other components.In addition, the preparation method of the glove includes three steps: batching, soaking and spraying.The glove and its preparation method have the following advantages. They not only have the properties of chemical resistance, strong acid resistance, strong alkali resistance and corrosion resistance, but also have low cost.In addition, the preparation method of the glove adopts pipelined production in the production process, which is simple in production process and low in cost, and suitable for large-scale industrial production.
