Heat-preserving material for outer wall

Abstract

The present invention discloses a heat-preserving material for an outer wall which comprises the following raw materials in parts by weight: 45-55 parts of coal ash silicate cement, 15-20 parts of white floating beads, 1.5-2 parts of nano TiO2, 0.5-1.2 parts of ceramic cotton fiber, 5-10 parts of aluminium silicate fiber cotton, 0.2-0.6 part of a water repellent, 3-7 parts of an elastic emulsion, 6-9 parts of swelled vitrified microbead heat-preserving slurry, 3.5-4.5 parts of polypropylene fiber, 2-5 parts of an inorganic nano coating, 0.05-0.1 part of foam filaments, 0.05-0.1 part of bamboo fiber and 10-15 parts of a flame retardant. The heat-preserving material for the outer wall has the characteristics of good heat preservation, thermal insulation, sound insulation, self-cleaning, ray resistance, water resistance, energy conservation and environment protection and high strength.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an external wall thermal insulation material. Background technique [0002] Civil engineering materials are one of the important basic raw materials for my country's economic development and social progress. Since mankind entered the 21st century, the requirements for living space and environment have reached an unprecedented height. This puts forward new requirements and challenges for the production, research, use and development of civil engineering materials. In particular, the construction of a well-off society, the comprehensive advancement of urbanization, and even the implementation of the entire modernization drive indicate that my country's economic development and social progress in the next few decades will have greater market demand for civil engineering materials. As far as the output of civil engineering materials is concerned, my country can be call...

Problems solved by technology

[0003] The Chinese patent with the publication number CN103043984B discloses an energy-saving thermal insulation material. The patent is mainly based on bricks and ceramic tiles construction waste, and rationally utilizes resources. This invention is applied after molding, and the work efficiency of the installers is low; the Chinese patent with publication number CN104556843A discloses a fireproof and thermal insulation material. , bentonite, polyacrylamide, penetrating agent, rare earth additives, pearl fly ash, rock wool as raw materials, among which rock wool has the disadvantage of strong water absorption and high thermal conductivity, which will easily lead to the decline of the performance of the insulation material

The insulation materials disclosed in these two patents do not have the effects of sound insulation and radiation, and their performance is easily reduced under long-term exposure to the sun
