Inner wall thermal insulation base layer paste, preparation and applications thereof

Abstract

The invention relates to the field of construction thermal insulation and energy saving, and specifically relates to an inner wall thermal insulation base layer paste, preparation and applications thereof. The inner wall thermal insulation base layer paste is composed of the following components in percentage by weight: 15 to 30% of inner wall putty thermal insulation powder, 0.1 to 1% of aqueous silane coupling agent, 1 to 5% of hydroxypropyl methyl cellulose, 6% to 22% of binding agent, 1 to 10% of auxiliary agent, and 60 to 74% of water. The inner wall thermal insulation base layer paste has the advantages of low cost, good waterproof property, small thermal conductivity, prominent thermal insulation effect, high strength, easiness in construction, and aqueous environment-friendliness, is capable of replacing the common putty in the market, and can create a temperature difference between the indoor and outdoor to a range of 5 to 15 DEG C in summer.

Description

technical field [0001] The invention relates to the field of building heat preservation and energy saving, in particular to an inner wall heat preservation base paste and its preparation and application. Background technique [0002] Based on the national conditions of tight resources and weak environmental carrying capacity. With the rapid development of social economy, thermal insulation and energy saving has become the focus of increasing attention of the whole society. In recent years, the environmental problems caused by global warming have been very prominent. All countries in the world have realized that if the control of energy consumption is not strengthened, it will lead to the deterioration of the human living environment in the long run, and eventually bring disaster to human society. Energy consumption accounts for about 30% of the total energy consumption of the whole society in our country, and the state has issued a series of policies for building insulation...

AI Technical Summary

Problems solved by technology

Most of the interior wall putty insulation powder has a hollow structure, poor physical strength, and easy water absorption

The putty prepared by a single untreated putty insulation powder often has disadvantages such as difficult construction, poor water resistance of the putty layer, insufficient strength, and poor flexibility.

If the addition of putty insulation powder is reduced, these shortcomings will be improved, but at the same time, the thermal insulation effect of the thermal insulation putty will become worse

Due to these shortcomings, the original interior wall thermal insulation putty is difficult to accept and widely used in the market.
