Embodiment 1

[0019] S1. First weigh 50 parts of boron phenolic resin, 8 parts of nano hollow glass beads, 12 parts of deionized water, 3 parts of preservative, 6 parts of nano silicon dioxide and 6 parts of cyclohexanol according to parts by weight.

[0020] S2, put the boron phenolic resin, preservative, and deionized water into the mixing equipment and stir and mix, the stirring rate is 550r / min, and the stirring time is 22min;

[0021] S3. Mix and stir the mixture obtained in S2 with nano-silicon and cyclohexanol at a rate of 350 r / min. During the stirring process, slowly add deionized water until it becomes colloidal to obtain the final product.

[0022] A performance test was carried out on the formed thermal insulation coating: the thermal conductivity at 25° C. was 0.25 W / (m·k).

Abstract

The invention provides a novel thermal insulation material. The novel thermal insulation material comprises the following components in parts by weight: 50-60 parts of boron phenolic resin, 10-25 parts of a nano silicon material, 10-20 parts of deionized water, 1-5 parts of a preservative and 6-10 parts of cyclohexanol. Physical and chemical composite modification is adopted to overcome the defects of single modification, and the characteristics of light weight, no toxicity, no corrosion, heat preservation, energy conservation, low cost and the like of traditional phenolic resin are reserved.And the advantages of high temperature resistance, instantaneous high temperature resistance, certain mechanical strength, toughness and wear resistance, which are not possessed by the material, are also added.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a novel thermal insulation material and a preparation method thereof. Background technique [0002] The serious trend of global warming has made heat insulation materials more and more popular among people. Whether it is construction or industry, a large number of heat insulation materials are used for heat insulation. The requirements for heat insulation materials are very high. In order to adapt to electronic In order to meet the new needs of high-tech fields such as automobiles, aviation, aerospace and national defense industries, it is necessary to modify thermal insulation materials. Traditional thermal insulation materials are expensive, have poor thermal insulation and heat resistance effects, and cause serious environmental pollution. With the advancement of science and technology, the shortcomings of pure phenolic resin, such as high brittleness, po...
