Environment-friendly silicon rubber and making method thereof

Abstract

The invention discloses environment-friendly silicon rubber and a making method thereof. The environment-friendly silicon rubber comprises the following components in percentage by weight: 62-63.1% of silicon crude rubber, 34.1-35.3% of white carbon black, 1.9% of silicone oil, 0.2-0.3% of zinc oxide and 0.6% of hydrogen containing silicone oil. The making method comprises the following steps of:a, preparing raw materials according to the proportions of a formula; b, adding the above raw materials into an internal mixer for internal mixing; and c, adding the internally-mixed materials into afilter for refining filtering, and slicing the filtered product to form a finished product of the environment-friendly silicon rubber. The invention has the advantages of having stable product quality, high transparency, favorable wear resistance, high elongation at break, high production efficiency, low production cost and capability of being used for mold pressing and extruding processes, belonging to high tearing resistance grade silicon gels, satisfying the supply requirements of enterprises on the raw materials, and improving the market competition ability of the enterprise.

Description

technical field [0001] The invention relates to a silicone rubber and a production method thereof, belonging to the technical field of new environmental protection materials, in particular to an environment-friendly silicone rubber and a production method thereof. Background technique [0002] With the development and innovation of science and technology at home and abroad, the requirements for products are getting higher and higher, and the formulation of standards is becoming more and more strict. Therefore, more environmentally friendly and safer products will become the mainstream of the market. Be one of the best. In the current domestic and foreign markets, silicone products have gradually replaced traditional plastic products. Silicone kitchen utensils have been accepted by more and more consumers. The world uses about 500 million pieces of kitchen utensils every year. It has become a big industry with a broad market potential. Prospects. [0003] However, in the ex...

Problems solved by technology

[0004] However, at present, the production capacity of domestic raw material silicone rubber manufacturers still cannot meet the material demand of silicone rubber product manufacturers, and a large part still needs to rely on imports

For enterprises that mainly produce silicone rubber kitchen utensils, kitchen supplies and daily necessities, due to different exporting countries, the hygienic standards of raw material silicone rubber are also different, and the types and hardness grades of silicone rubber required for different uses of silicone products and utensils The resistance to high and low temperatures is also different. If you want to ensure normal production, you must stock a variety of silica gel raw materials, which will cause a backlog of working capital for the enterprise.

On the other hand, most of the raw material silicone rubber currently circulating in China are general-purpose materials, which cannot meet the production requirements. The product scrap rate is high, and the production efficiency is not high, resulting in the continuous increase of production costs.
