Abstract

The invention discloses a foaming agent for silicone rubber sponge. The foaming agent consists of the following raw materials by weight: 8-12 parts of azodicarbonamide, 5-8 parts of trinitroso-trimethylene triamine, 4-6 parts of DPSDSH, 2-3 parts of p,p-oxydi(benzenesulfonyl semicarbazide), 3-5 parts of sodium bicarbonate, 2-4 parts of sodium citrate, 2-4 parts of melaniline, 20-30 parts of glycerol, 2-5 parts of oxalic acid, 2-3 parts of pentaerythritol and 0.5-1.5 parts of zinc oxide. The foaming agent provided by the invention has excellent foaming capacity, high foaming rate and process stability; and the produced foam has good temperature adaptability, dispersion uniformity, low cost and easy usage. The silicone rubber sponge material prepared from the foaming agent provided by the invention has uniform and beautiful appearance, good mechanical properties, low density, fine and uniformly dispersed micropores, porosity reaching 75% and neck mould expansion rate reaching 400%.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a foaming agent for silicone rubber sponge. Background technique [0002] Sponge rubber is widely used in sealing, shock absorption, heat insulation, sound insulation, printing and dyeing, and ion exchange due to its structural particularity, that is, porosity, which can produce various special effects. It has been widely used in aerospace, aviation, transportation, petroleum, chemical industry, pharmaceuticals, instrumentation, style and daily life. Silicone rubber sponge, in addition to the functions of shock absorption, sound insulation, heat insulation, and sealing that sponge rubber has, also has special properties such as high-energy impact resistance and high electrical and thermal insulation properties unique to silicone rubber, and is widely used in the electronics industry and space. Technology, at the same time, silicone rubber sponge is also physiologically inert, non-toxic, odorle...
