Problems solved by technology

However, due to the high thermal conductivity of the inorganic gel material, the thermal insulation performance of the final expanded perlite product drops sharply
In addition, the high water absorption of the product is also a problem that must be solved for this type of material. Although water repellent or vitrification treatment is sometimes used for perlite, the bubble body will inevitably be damaged during the mixing process with the cementitious material, making the perlite Hydrophobic treatment is invalid, and the insulation performance is further reduced

Abstract

The invention belongs to the field of a thermal insulation material and preparation thereof. The invention discloses a compound thermal insulation material taking phenolic resin and expanded perlite as main raw materials and a preparation method of the compound thermal insulation material. The preparation method comprises the following steps: uniformly mixing phenolic resin, expanded perlite and fire retardant; filling into a mould; solidifying and forming at a certain temperature for a period of time. Thermoset phenolic resin is selected as the phenolic resin and the dosage is 20wt%-70wt%; perlite in bulk density of 90-120kg/m3 is selected as the expanded perlite and the dosage is 30wt%-80wt%; half-dry pressing is performed under the forming temperature of 100 DEG C for forming time of 2h; the apparent density of the sample is 200-360Kg/m3, the compressive strength is 0.8-1.2MPa, the breaking strength is 0.4-0.7MPa and the combustion performance is B1 level; the overall performance of the material is between the organic and inorganic thermal insulation materials at present. The compound thermal insulation material provided by the invention has the advantages of low heat conductivity coefficient of organic thermal insulation materials and high strength and difficulty in burning of the inorganic thermal insulation material.

Description

technical field [0001] The invention relates to the field of thermal insulation materials and their preparation, and relates to a composite thermal insulation material with phenolic resin and perlite as main raw materials and added flame retardant components and a preparation method thereof. Background technique [0002] According to relevant statistics, most of the buildings in our country are high-energy buildings, and the energy consumption per unit area is 2-5 times higher than that in developed countries. Therefore, thermal insulation materials have gradually become an effective way to solve the problem of high energy consumption in our country. However, with the fire incidents caused by thermal insulation materials in my country in recent years, the fire prevention of thermal insulation materials has begun to attract people's attention. [0003] At present, the commonly used wall insulation materials in my country are divided into three categories: organic insulation ...
