Abstract

The invention provides a multifunctional thermal-insulating and heat-preserving phenolic-resin type foam board and relates to the field of building materials. The multifunctional thermal-insulating and heat-preserving phenolic-resin type foam board comprises the following materials in parts by weight: 75-100 parts of phenolic resin, 6-15 parts of liquid rubber, 1-2 parts of cashew nut shell oil, 0.1-0.3 part of molybdenum trioxide, 0.1-0.2 part of zinc oxide, 2-3 parts of inorganic nanoparticle, 0.1-0.3 part of boron fiber, 0.5-1 part of magnesium hydroxide, 0.5-1.5 parts of aluminium hydroxide, 3-5 parts of alkylphenol polyoxyethylene type surface active agent, 0.2-0.5 part of metallic soap, 0.5-1.5 parts of hosphate, 8-12 parts of petroleum ether, 0.3-0.5 part of alkyl sodium sulfonate, 0.1-0.5 part of pentaerythritol ester, 0.1-0.5 part of phenyl salicylate, 0.2-0.3 parts of silicone, 1-1.5 parts of waterproof agent and 6-10 parts of curing agent. The multifunctional thermal-insulating and heat-preserving phenolic-resin type foam board provided by the invention not only has the thermal-insulating and heat-preserving effects, but also has the advantages of high mechanical strength, moisture-proof and fire-proof effects, weather resistance and wide temperature application range and the like.

Description

technical field [0001] The invention relates to the field of foam boards, in particular to a multifunctional thermal insulation phenolic resin foam board. Background technique [0002] With the rapid development of industrialization in various countries, the fossil fuel available to human beings has been exhausted day by day, and the energy problem is serious. The sustainable development strategy requires that while actively developing new energy sources, attention should also be paid to energy conservation. Building energy consumption accounts for a high proportion of human energy consumption. Therefore, building energy conservation is an effective way to solve my country's energy problems. The most direct way of building energy conservation is to use thermal insulation materials, which can reduce the amount of foam boards and improve construction efficiency. Therefore, the research, development, promotion and application of good building thermal insulation materials are of ...

AI Technical Summary

Problems solved by technology

[0004] There are different degrees of defects in the application of thermal insulation materials currently used: in the state of moisture, perlite is prone to corrosive calcium oxide, retains moisture for a long time, and is not easy to use in low temperature environments; glass fiber It is easy to absorb water and is not suitable for low temperature environments, nor is it suitable for high temperature environments above 540 degrees; mineral cotton also has water absorption and is not suitable for low temperature environments, but can only be used in high temperature environments with moisture; polyurethane foam and polystyrene Ethylene foam should not be used under high temperature conditions, and it is flammable, shrinks, and produces poisonous gas; foam glass is not suitable for use under conditions of rapid temperature changes due to its sensitivity to thermal shock
