Abstract

The invention relates to a foam material and provides a liquid flame-retardant assembly line foamed silica gel material and a preparation method thereof. The foaming ratio of the liquid flame-retardant assembly line foamed silica gel material is extremely high, has excellent flame retardance, and is small in foaming density which can reach 0.16-0.43 g / cm<3>, and the foaming density is approximately between that in open cell foaming and closed cell foaming. The liquid flame-retardant assembly line foamed silica gel material is good in high-temperature thermal shrinking effect, uniform in pore diameter, high in compression strength and good in sealing property, and relatively good dimensional stability of the liquid flame-retardant assembly line foamed silica gel material in a using processcan be kept, sealing failure can be avoided effectively, and the maintenance cost is lowered. The preparation method of the liquid flame-retardant assembly line foamed silica gel material adopts an automatic continuous assembly line foaming process, so that the foaming efficiency is high, the demands on preparation staff are reduced, the labor intensity of the staff is reduced, the processing andmanufacturing costs are lowered, and the liquid flame-retardant assembly line foamed silica gel material is suitable for batched production, manufacturing and application.

Description

technical field [0001] The invention relates to a foaming material, in particular to a liquid flame-retardant pipeline foaming silica gel material and a preparation method thereof. Background technique [0002] Silica gel has the characteristics of organic polymer elastomers and the wide range of high and low temperature adaptability of inorganic substances. It has become the material of choice in military aerospace, medical, automobile, construction and other fields. Foaming silica gel is a foaming agent added to the rubber material. During the vulcanization process, the foaming agent decomposes at high temperature to generate air bubbles, which are wrapped in silicone rubber to form foamed silica gel. The foamed silicone material not only maintains the original excellent properties of silicone, but also has the characteristics of heat insulation, sound insulation, shock absorption, and light weight of the product. The application field of the foamed silicone material has b...
