Problems solved by technology

JP-A-59-U832 pointed out that the condensation reaction curing type silicone latex formed by two-terminal hydroxyl-terminated diorganopolysiloxane and an organotin catalyst is frozen and solidified, and the water is removed after thawing to make a silicone rubber sponge. In this method, the energy and time for freezing and thawing are large and the production efficiency is deteriorated, and there is a problem of poor heat resistance due to the presence of an organotin catalyst
On the other hand, hydrosilylation reaction crosslinkability, that is, addition reaction curable silicone rubber latex, and a method for producing silicone rubber and a coating film from the latex are known, but addition reaction curable silicone rubber sponge Latex compositions, and methods of making silicone rubber sponges from the latex, are not known

Abstract

The invention relates to a composition. The composition comprises the following components in percentage by weight: 20-30% of a 3-5-Chloro-2-methyl-4-isothiazolin-3-one derivative, 10-25% of metal nitrates, 1-10% of alkali metal hydrochloride, 0-0.02% of a hydrogen peroxide solution, and 2-5% of a composition of methyl acrylate, ethyl acrylate, butyl acrylate, acrylic 2-octyl nitrite, and decyl acrylate. The composition disclosed by the invention has the advantages of favorable stretching strength and extensibility, and when an emulsion is immersed in a coagulant, the solidification can be promoted. The elasticity is good and the service life is long.

Description

technical field [0001] The present invention relates to a composition. Background technique [0002] Silicone rubber sponge, because of its excellent heat resistance, weather resistance and light weight, can be flexibly used as packaging materials, gaskets, O-rings and other automotive parts; surface coating materials for copier rollers; various sealing materials, etc. Originally, in order to form such a silicone rubber sponge, the following various compositions have been proposed. For example, Japanese Patent Application Laid-Open No. 44-461 and Japanese Patent Application Laid-Open No. 7-M7436 propose a composition for forming a silicone rubber sponge composed of a thermally decomposable organic foaming agent represented by azobisisobutyronitrile, Japanese Patent Application Laid-Open No. 5-209080 A composition for forming a silicone rubber sponge in which the outer shell is made of a thermoplastic and contains air cells containing volatile hydrocarbons such as butane and...
