活性氧化镁与橡胶制品的关系

With the gradual popularization of tire, wire and cable industry, more private funds have entered the rubber market, which once led to the situation of oversupply in the rubber market. However, with the popularity of cars and other things, the rubber industry has slowly returned to normal. Magnesium oxide is of great use in rubber production. Active magnesium oxide can also be used as an additive for FRP, fluororubber, medical rubber stopper and other products. In addition, active magnesium oxide can be used as filler of paint, paper and cosmetics, filler and reinforcement of rubber and other auxiliary materials that need adsorption because of its high dispersion and adsorption. These industries usually choose active magnesium oxide with large apparent specific volume, large volume and good dispersion as acid absorbent and vulcanization accelerator, which can improve the performance of products such as high temperature resistance, fire resistance, flame retardancy, wear resistance, corrosion resistance and anti scorching.

① Active magnesium oxide is mainly used as the reinforcing agent of rubber to make the rubber have good corrosion resistance, tear resistance, elasticity and elongation.

② The accelerator used in rubber vulcanization process is a multifunctional rubber compounding agent, which is mainly used as vulcanizing active agent and reinforcing agent of natural rubber, synthetic rubber and latex.

③ When used as vulcanization active agent, it is evenly distributed in the rubber, has a large contact area with hydrogen sulfide, and has a great opportunity for interfacial reaction. In addition, the active magnesium oxide product has the catalytic effect of active substances, so that the conversion rate of magnesium oxide is high.

④ As a vulcanization oxidant, its function is to improve the activity of accelerator, reduce the dosage of accelerator and shorten the vulcanization cycle.

⑤ It can accelerate the vulcanization speed, improve the thermal conductivity of vulcanizate and make vulcanization more thorough.

⑥ In the rubber industry, especially in the production of transparent rubber products, active magnesium oxide is an excellent vulcanizing active agent.
