Roof wall surface heat insulation building material and manufacturing method thereof

Abstract

The invention provides a roof wall surface heat insulation building material. The heat insulation building material comprises a surface layer and a bottom layer, wherein at least one layer of reflecting material is arranged between the surface layer and the bottom layer. At least one secondary heat insulation layer is arranged between the reflecting material layer and the bottom layer. The reflecting material layer is a polyester film or aluminum foil which is plated with a reflecting metal material on both sides. The reflecting metal material plated on the polyester film is aluminum, silver, chromium or zinc which has a physical property of separating radial so the sun light cannot penetrate. The secondary heat insulation layer is one of regenerating fiber, rock wool, asbestos, glass cloth and quartz fiber, has a physical property with small coefficient of heat conductivity, and is capable of resisting heat, so the products of the invention have obvious heat insulation effect. Besides, the manufacturing method of the products of the invention has the advantages of simple process, small investment and easy popularization. The material of the invention can be directly paved on roof without being built on stilts and without connection so the use is convenient.

Description

【Technical field】 [0001] The invention relates to a heat-insulating building material for roof and wall surfaces and a manufacturing method thereof, belonging to the field of heat-insulating building materials. 【Background technique】 [0002] The existing thermal insulation building materials in the domestic market include traditional cement boards, new foam thermal insulation boards, and coating composite materials. Their common disadvantages are: 1. Poor thermal insulation effect; 2. Short life, generally 3- It needs to be replaced in 5 years; 3. It is not environmentally friendly, and the plastic foam after replacement is difficult to dispose of; 4. The construction is complicated and needs to be elevated or connected; 5. The investment in setting up a factory is large, usually more than 5 million yuan. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a roof and wall heat insulation building material and four manu...
