Technical field:

The invention relates to the technical field of latex balloon, in particular to a new environmental protection balloon and a production method thereof.

Background technology:

Natural rubber emulsion is polyisoprene as the main body, and there are more than ten components of the material.It is mainly used to produce impregnated products such as medical gloves, special protective gloves for nuclear industry, rubber hose, medical catheter, balloon, condom, baby nipple and fingertip.Traditional natural rubber latex and chemical plus sulfur, zinc oxide and sulfide is vulcanization accelerator, the latex with the natural latex as follows 100% measured in dry glue, sulfur S 0.8%, promoter TNTD 0.6%, zinc oxide (ZnO) 0. 3 to 0. 5%, antiager D 0. 5 to 0. 7%, promoter ZDC 0. 5-1%, 10% KOH 40 kg per ton dry glue, rubber latex with stirring reaction cylinder heating up to 35 to 40 ° C, the above mixture slowly to join after fine grinding,Then it is raised to 60-62°C and kept for 3 hours. When it is cold enough to room temperature, the material can be discharged, but it must be kept for 3 days before use.Its products contain sulfur, which is not suitable for special medical use and high performance mechanical and electrical products manufacturing.In addition, the chemical water soluble egg white matter content is higher in sulfide products, reports of allergic reactions has led to the human body, therefore the United States food and drug administration (FDA) on July 30, 1999, a statement to medical gloves industry, put forward the soluble protein content in each glove should be less than 1200 yg regulation, currently used on industrial chlorination to reduce the content of soluble protein, though effective, but will also affect the environment of chloride wastewater;Moreover, when the chemical vulcanization by adding the vulcanization accelerator in the vulcanization process will produce nitramine, it is recognized carcinogenic substances, the relevant countries on the content of nitrosamine latex products have put forward strict restrictions on the standard.Based on the above disadvantages of the chemical vulcanization method, the balloon product made by using the chemical vulcanization latex contains a certain amount of nitrosamines and soluble proteins, which is not conducive to human health and environmental protection.

The invention content

The purpose of the invention is to provide a new environment-friendly balloon production method to make up for the shortage of the existing technology. The balloon produced by this method is environment-friendly, containing no sulfur, no nitrosamine and low soluble protein content, with short production cycle, simple method and easy implementation.Of the technical scheme of the invention is as follows, a new type of green balloon production methods, the characteristic is to include the following step step one, natural latex as matrix, according to the following quality proportion made from natural rubber latex raw materials, 100, measured at the dry glue ammonia, concentration of solution, 0.75% 0.2 servings, Κ 0 Η, solution concentration 10%, 0.2,

5.0 pieces of butyl acrylate, stir for at least 30 minutes after batching;Step 2. Use low-energy electron accelerator or gamma irradiation device to cure the above ingredients by radiation. The absorbed dose of radiation curing is controlled at 2535 kilogy, and the next step can be carried out after irradiation.Step 3. Add various kinds of colored materials to the radiant vulcanized latex and stir it to produce various colored pastes which are sent to the color pastes pool of the production line for later use.Step 4: prepare the balloon model, including (1) clean the model. Firstly, acid wash the model with 35% hydrochloric acid solution for 2 to 3 seconds and rinse with water.Then use sodium carbonate solution with a concentration of 10 15% to wash for 2 or 3 seconds and rinse with water. The cleaning time of a single mold should be controlled within 30 seconds.(2) the drying temperature of the model is 60-70°C and the drying time is 50 and 70 seconds. The moisture on the model is dried and the model has a certain residual temperature, which is convenient for coagulant adsorption.(3) model impregnating coagulant the model is impregnated in a coagulant tank. The coagulant is prepared by adding diatomite powder with a mass percentage of 10% to Ca(N03) 2 solution with a mass percentage of 20%.Dipping time: 6 10 seconds;(4) after the model is soaked with coagulant, the model is dried at a temperature of 60-70°C and a drying time of 40 and 60 seconds. The water in the coagulant is dried and the coagulant is adsorbed on the model surface.Step 5: dip the color paste and put the model with adsorbed coagulant into the color paste pool. When the radiation vulcanized latex meets the coagulant on the mold, it will solidify on the model.Tank temperature 20 25°C, dip time 40 60 seconds;Step 6. The drying temperature is 60_65°C, the drying time is 3.5 minutes, and the water in the latex solidified on the model is removed.Step 7. Roll the edge of the balloon blowing mouth with the edge roller, so as to strengthen the edge of the mouth strength, not easy to tear;Step 8. Put into a long tank of hot water for zhejiang filtration with a water temperature of 80 °C and a zhejiang filtration time of 30 and 50 seconds. The main purpose is to remove impurities on the surface of the balloon and elute some soluble substances, including water-soluble proteins.Step 9. Heat and finalize the design. Heat and finalize the design in the baking passage with a temperature of 85 90°C.Step 10. Online demodulation: the balloon products can be obtained by automatically blowing off the balloon from the model with the high-pressure water flow with the pressure of 0.3-0.5mpa.Further, it is characterized by the following steps: (11) cleaning and demineralizing. As the coagulant contains diatomite powder, the residual powder on the surface of the balloon is removed by water washing. The water temperature is normal temperature or 60 °C, and the cleaning time is 15 and 20 minutes.Step 12, inspection packaging sampling inspection balloon appearance and inflation inspection after packaging.Furthermore, a new type of environmental balloon is characterized in that it is produced by the above method.The new environmental protection balloon of the invention is made of rubber latex with gamma ray or low-energy electron beam radiation vulcanization as raw materials, which has the characteristics of no sulfur, no nitrosamine and low water-soluble protein content.According to the test, the water-soluble protein content of this product is no more than 50yg/g, no nitrosamine content (test standard GB/ t24153-2009), and no sulfur content.
