Environmental protection and energy saving thermal insulation material for building

Abstract

The invention discloses an environmental protection and energy saving thermal insulation material for building, which is characterized in that the material provided by the invention is produced by mixing and stirring meerschaum, lightweight whitewash gypsum, hydrophobic perlite, aluminous cement, composite fiber (consisting of propylene fiber, wood fiber and fiber brucite), composite adhesive (consisting of methyl hydroxyethyl cellulose ether, starch ether and redispersible emulsion powder), air entraining water reducer, hydrophobic agent and calcium salt of polymethylene amino acid with dry powder appearance. Water is added into the material, after mixing and stirring, the material provided by the invention can be directly plastered to exterior wall, interior wall and roof of house with a certain thickness, and has the advantages of good insulation and heat insulation effects, moistureproof and waterproof, simple construction operation, and reduced additional cost.

Description

Technical field: [0001] The invention relates to building materials, in particular to a building environmental protection, energy saving and thermal insulation material. Background technique: [0002] At present, regardless of the construction of residential buildings or factory buildings and office buildings, strengthening building energy conservation management, improving energy utilization efficiency, and improving indoor environmental quality have become an indispensable part of the construction industry. , the state has repeatedly issued corresponding policies to encourage the development of building energy-saving technologies and products. An important aspect of building energy saving is the heat preservation and energy saving of building walls. At present, the main measures adopted in my country in terms of wall insulation and energy saving have two aspects: 1. Single wall insulation measures: mainly adopt wall materials with good thermal performance, and do not add ...

AI Technical Summary

Problems solved by technology

Among the above two methods, the thermal insulation effect achieved by a single thermal insulation measure is far from enough, especially in cold regions, which cannot meet the thermal insulation effect required by the country.

At present, the domestic composite wall insulation materials also have many shortcomings, such as cumbersome construction when using benzene board for insulation, high additional cost, short service life of benzene board material, and easy drumming and cracking

The thermal performance of thermal insulation mortar is low, the waterproof and moisture-proof effect is poor, and the thermal insulation efficiency is low
