Novel flexible silica gel and preparation method thereof

Abstract

The invention discloses novel flexible silica gel and a preparation method thereof, and belongs to the technical field of flexible silica gel. The preparation method of the novel flexible silica gel uses the following components: deionized water, a silica gel material, carbon black, a vulcanizing agent, a bridging agent, an antistatic agent and hydroxymethyl cellulose, and further uses the following components: an anti-aging agent, a tackifying agent and a filler. According to the method provided by the invention, the hydroxymethyl cellulose and the deionized water are put into a reaction kettle, stirring and heating are performed, then the silica gel material, the bridging agent, the anti-aging agent, the tackifying agent and the filler are put, so that the flexible silica gel has a better anti-aging effect and does not cause breakage or slitting after being used for a long period of time, the problem that the service life is reduced because flexible silica gel has a larger permanentdeformation rate after being subjected to stretching action can be avoided, and the flexible silica gel can eliminate most of mechanical stress and has shock absorption protection effects, has stablephysical and chemical properties and low production costs, and is suitable for promotion and applications.

Description

technical field [0001] The invention relates to the technical field of flexible silica gel, in particular to a novel flexible silica gel and a manufacturing method thereof. Background technique [0002] Silica gel, also known as silicic acid gel, is a highly active adsorption material, which is an amorphous substance. It does not react with any substance except strong alkali and hydrofluoric acid. It is insoluble in water and any solvent. It is non-toxic and tasteless. Stable, the chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel can be divided into macroporous silica gel, coarse-porous silica gel, B-type silica gel, and fine-pore silica gel according to its pore size.

Problems solved by technology

[0003] In today's life, people are using more and more flexible silicone, but the existing flexible silicone has poor texture and is prone to aging after long-term use, which affects people's use effect, and the existing flexible silicone is poor in elasticity. After being stretched, the permanent deformation rate of the material is large, which reduces its service life, and the existing flexible silicone is troublesome to manufacture, and the production cost is high, which reduces its use value
