Embodiment 1

[0007] Take 40kg of vinyl tertiary carbonate copolymer, put it into the reaction kettle, add 10kg of vinylidene chloride copolymer, stir evenly, then add 30kg of hydroxypropyl cellulose, keep stirring, add 10kg of mica powder, and then add 10kg of sodium silicate, Add 10 parts of epoxy resin, then add 20 parts of talcum powder, and then add 50 kg of water. The finished product can be obtained after fully stirring. Using a thermal conductivity meter to measure the thermal insulation coating containing vinyl tertiary carbonate copolymer, the thermal conductivity of the coating is 0.023 W / (m·k). The national standard GB / T9755-2001 is used to measure the water resistance and alkali resistance of the coating. The saturated calcium hydroxide solution is used for alkali resistance. The coating has no abnormal conditions such as foaming within 100 hours. The invention has good thermal insulation and water resistance. Alkali resistant effect.

Embodiment 2

[0009] Take 50kg of vinyl tertiary carbonate copolymer, put it into the reaction kettle, add 20kg of vinylidene chloride copolymer, stir evenly, then add 40kg of hydroxypropyl cellulose, keep stirring, add 20kg of mica powder, and then add 20kg of sodium silicate, Add 20 parts of epoxy resin, then add 10 parts of talcum powder, and then add 80 kg of water. After fully stirring, the finished product can be obtained. Using a thermal conductivity meter to measure the thermal insulation coating containing tertiary vinyl carbonate copolymer, the thermal conductivity of the coating is 0.020W / (m·k). The national standard GB / T9755-2001 is used to measure the water resistance and alkali resistance of the coating. The saturated calcium hydroxide solution is used for alkali resistance. The coating has no abnormal conditions such as foaming within 100 hours. The invention has good thermal insulation and water resistance. Alkali resistant effect.

Embodiment 3

[0011] Get 45kg of vinyl tertiary carbonate copolymer, put it into the reaction kettle, add 15kg of vinylidene chloride copolymer, stir evenly, then add 45kg of hydroxypropyl cellulose, keep stirring, add 15kg of mica powder, then add 15kg of sodium silicate, Add 15 parts each of epoxy resin and talcum powder, and then add 70 kg of water. After fully stirring, the finished product can be obtained. Using a thermal conductivity meter to measure the thermal insulation coating containing the vinyl tertiary carbonate copolymer, the thermal conductivity of the coating is 0.030W / (m·k). The national standard GB / T9755-2001 is used to measure the water resistance and alkali resistance of the coating. The saturated calcium hydroxide solution is used for alkali resistance. The coating has no abnormal conditions such as foaming within 100 hours. The invention has good thermal insulation and water resistance. Alkali resistant effect.

Abstract

The invention relates to a thermal insulating coating containing vinyl versatate copolymer. The thermal insulating coating is composed of the following components in weight ratio: 40-50 parts of vinyl versatate copolymer, 10-20 parts of vinyl chloride copolymer, 30-40 parts of hydroxyl propyl cellulose, 10-30 parts of mica powder, 10-20 parts of sodium silicate, 10-20 parts of epoxy resin, 10-20 parts of talcum powder, and 50-80 parts of water. The prepared coating containing vinyl versatate copolymer is good in thermal insulating effect.

Description

technical field [0001] The invention relates to a thermal insulation coating, in particular to a thermal insulation coating containing tertiary ethylene carbonate copolymer. Background technique [0002] With the rapid and continuous development of my country's urban construction and home decoration market, people's demand for coatings is increasing, especially the market demand for thermal insulation coatings is also increasing year by year. Types of thermal insulation coatings, their quality varies greatly, a large part of thermal insulation coatings have the problem of poor thermal insulation and heat insulation effects, and they also have the disadvantages of high cost and high energy consumption, so the invention has low thermal conductivity and good thermal insulation effect The coatings are more and more urgent to apply them to the corresponding market segments. Contents of the invention [0003] The problem to be solved: the problem of poor thermal insulation effec...
