Abstract

Belonging to the field of curing agents, the invention particularly relates to a silica gel curing agent for preparation of a thermal insulation material and a preparation method thereof. The silica gel curing agent prepared according to the invention is based on a silica gel framework material, filler and a surfactant are added to reach the effects of promoting gel curing, strengthening the gel skeleton structure and passivating the surface in a gel-sol process, meanwhile, the surface tension change in the gelling process can be effectively inhibited, gas-liquid dispersion in the system reaction process is eliminated, the gel preparation process is optimized, the structure of the gel can be kept without collapse during normal-pressure drying, and the mechanical properties and the heat preservation and insulation effect of the obtained silica gel material are remarkably improved.

Description

technical field [0001] The invention belongs to the field of curing agents, and in particular relates to a silicone gel curing agent for preparing thermal insulation materials and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of science, people have higher and higher requirements for the quality of life. In the face of increasingly serious noise pollution and global warming, it is particularly important for people to have a comfortable working and living environment. In the face of noise and heat problems, the main means that can be solved through human intervention are: use certain materials to block noise and high temperature. [0003] In terms of thermal insulation, Chinese patent CN103087605B discloses a water-based nano thermal insulation material and a preparation method thereof. The material is composed of porous water-based nano-SiO 2 Suspension emulsion, inorganic nano-TiO 2 , inorganic nano-bismu...
