Vulcanization accelerator, environment-friendly latex sponge, preparation method and application

Abstract

The invention discloses a vulcanization accelerator, environment-friendly latex sponge, a preparation method and application. The vulcanization accelerator comprises 100 parts of silicon dioxide; 40-100 parts of strong base; 1-20 parts of cerium salt; and 40-100 parts of carbon disulfide. The preparation method comprises the step of loading xanthate on silicon dioxide. The environment-friendly latex sponge comprises 100 parts of latex, 1-2 parts of an anti-aging agent, 1-3 parts of sodium silicofluoride, 0.5-2 parts of a foaming agent, 4-25 parts of the vulcanization accelerator and the like. The preparation method comprises the following steps: preparing the auxiliary agents into dispersoid, mixing, stirring, injecting into a mold, gelling, vulcanizing, demolding, washing with water and drying. The prepared environment-friendly latex sponge can be used in the fields of furniture, automobiles or sanitation. The vulcanization accelerator provided by the invention is good in thermal stability, does not decompose after being stored for a long time at room temperature, does not release pungent smell, and is environment-friendly. The environment-friendly latex sponge is good in buffering effect and has excellent stretch resistance and rebound resilience.

Description

technical field [0001] The invention relates to the technical field of rubber modification, in particular to a vulcanization accelerator, an environment-friendly latex sponge, a preparation method and an application. Background technique [0002] Latex sponge is a kind of porous rubber material with a cell structure and the cell structure is all connected holes or most of the cells are connected and a small part is not connected. It is the type of latex product that consumes the largest amount of latex. Latex sponge has the characteristics of high elasticity, shock absorption, compression fatigue resistance, good bearing capacity, comfort and durability, so it is widely used in many aspects such as automobile industry, medical equipment, daily hygiene and sporting goods. Latex sponges usually need to add rubber accelerators during preparation. In the rubber industry, rubber accelerators are specifically vulcanization accelerators. Vulcanization accelerators can promote the v...

Problems solved by technology

[0004] Xanthate is a non-toxic, non-polluting, environment-friendly rapid vulcanization accelerator, its molecular structure is (R 1 is an alkyl or aryl group, Me is a metal atom Na, K, Zn, etc.), does not contain nitrogen atoms, and thus does not produce nitrosamines during the vulcanization process, but the xanthate accelerator has poor stability and will Decomposes slowly, needs to be stored at low temperature below 10°C, and has a special unpleasant smell, which limits its application in latex sponge products
