A kind of environment-friendly rubber release agent

Abstract

The invention discloses an environment-friendly rubber isolation agent. The isolation agent comprises the following components in parts by weight: 24-36 parts of polyoxyethylene sorbitan monooleate, 2-4 parts of waterborne polyamide wax, 30-38 parts of calcium stearate, 18-30 parts of hydrated silicon dioxide, 8-14 parts of potassium stearate, 2-5 parts of silicone oil defoaming agents and 2-6 parts of sodium carboxymethylcellulose. The isolation agent is excellent in compatibility, long in actual effect and low in addition amount, and is green and environmentally friendly; the preparation process of the environment-friendly rubber isolation agent is simple and feasible; the cost is low.

Description

Technical field [0001] The invention relates to a release agent, in particular to an environmental protection rubber release agent. Background technique [0002] The film isolation system plays a stable but very important role in the tire manufacturing industry. In the production process of various rubber products, due to the self-adhesiveness of the rubber compound, the contact of the rubber material during the processing will lead to varying degrees The mutual adhesion of the rubber compound causes difficulties in subsequent processing, transportation and storage. Therefore, before the rubber compound is finally made into a finished product, such as before handling and storing the rubber compound, extrusion, extrusion and hot mixing, the corresponding A layer of release agent is coated on the film to prevent the film from sticking to each other; at present, the application of release agent is more and more extensive, and the varieties are also diverse.

[0002] The film isolation system plays a stable but very important role in the tire manufacturing industry. In the production process of various rubber products, due to the self-adhesiveness of the compound rubber, the contact of the rubber material during the processing will lead to varying degrees. Therefore, before the rubber compound is finally made into a finished product, such as before handling and storing the rubber compound, before extrusion, extrusion and thermal mixing, the corresponding A layer of release agent is coated on the film to prevent the films from sticking to each other; at present, the application of release agent is more and more extensive, and the varieties are also diverse. The existing products include four forms: paste, liquid, powder, and suspension The release agent is used by a large number of rubber product manufacturers, but as a rubber processing aid that has a negative effect on rubber properties, there are few reports in the industry on the impact of the form and performance of the release agent on the physical and mechanical properties of rubber. The basic requirement of the film release agent in the industry is that the release agent should not only have an excellent release effect but also have no adverse effects on the properties of the rubber compound. The main components of solid and liquid release agents such as soap paste are sodium fatty acid soap, which is composed of animal fat It is made by saponification, and the price is generally low, but the isolation effect is poor, and it has a great impact on the performance of the rubber. The powder release agent is mainly a surfactant and its compound product. At the beginning, it is mainly some imported products, which have a good isolation effect. It has little effect on the performance of the rubber compound. The main problem is that the price is high. In recent years, with the development of technology, there have been many manufacturers of powdery release agents in China. The price is relatively cheap but the quality is uneven. Some have poor isolation effects and exist Problems such as delamination, precipitation, and powder drop after drying have a greater impact on the rubber compound. Therefore, tire and rubber product manufacturers are trying to find a more cost-effective, better isolation effect, less negative influence, and easier to use. Convenient film release agent to achieve excellent isolation effect while reducing energy consumption, material costs and improving production efficiency

[0003] At present, although there are several types of rubber release agents, the ingredients basically contain industrial soap powder. As we all know, soap powder is the main raw material for preparing laundry, which contains a certain amount of phosphorus compounds, and phosphorus compounds are harmful to water bodies. It has a certain harmful effect, which can make the water body eutrophic, cause algae and other plankton to multiply rapidly, the dissolved oxygen in the water body decreases, the water quality deteriorates, and fish and other organisms die in large numbers. This problem has increasingly caused rubber Therefore, the development trend of the tire industry is to minimize the environmental hazards of tires in production and use. From the source, it is to use environmentally friendly or harmless tires as much as possible when designing tires. Compounding agent to realize the green development of tire products and industry
