Self-adhesive plastic-coated inorganic heat insulation board

Abstract

The invention discloses a self-adhesive plastic-coated inorganic heat insulation board. The self-adhesive plastic-coated inorganic heat insulation board comprises a heat insulation board body, wherein the heat insulation board body is an inorganic material heat insulation layer; the self-adhesive plastic-coated inorganic heat insulation board further comprises an adhesive fixing agent; the adhesive fixing agent is adhered to the inner side of the heat insulation board body; a fixing ring is arranged at the outer side of the heat insulation board body; the fixing ring is a rivet mounting reserved hole. The heat insulation board body is formed from coarse, medium and fine three inorganic materials which are preferred according to the requirement in material selection, then adding a hydrophobic material, mixing and uniformly stirring all the materials, and pressing, drying and the like, and after that the adhesive fixing agent is adhered to the inner side of the heat insulation board body; the fixing ring is arranged at the outer side of the heat insulation board body. After the materials are dried to the absolute dryness of 100 percent, coating plastic to a face layer is made, wherein a plastic coating material reaches a B1 standard in China, and the plastic-coated material (board) can be resistant to stretching and bending better, and has the waterproofness reaching 100 percent. The self-adhesive plastic-coated inorganic heat insulation board is unlikely to damage, convenient to mount in a construction process, unlikely to peel off and layer, and greatly prolonged in service life period.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a self-adhesive plastic-coated inorganic thermal insulation board. Background technique [0002] Existing composite insulation boards are usually composed of high-density boards and polystyrene foam layers compounded between high-density boards. Although this polystyrene foam composite board has the advantages of light weight and good sound insulation effect, its fireproof effect is poor. The polystyrene foam inside the composite board is very easy to burn in case of fire, fueling the fire and posing safety hazards. In order to solve the problem of fire prevention, a new type of inorganic composite insulation board has appeared on the market. The insulation board is made of perlite or vitrified microbead material, and has a good fireproof effect. It is easy to break during handling and use. In addition, due to its low strength, it is impossible to produce large-sized insulation...

AI Technical Summary

Problems solved by technology

[0005] The strength of the finished material (board) is low, the finished product is loose and brittle, and it is easy to be damaged, which makes it more difficult during the construction process;

[0006] The water-repellent rate of the finished material (board) should reach 99% according to the national standard, but the finished product (board) on the market becomes slag due to rain, water leakage and other reasons, and cannot achieve the effect of waterproof and heat insulation. Even less than the national standard requirements

No matter it is used for roof or wall insulation, it is prone to secondary expansion, which cannot guarantee the quality of the project;

[0007] The finished material (board) belongs to the hard inorganic thermal insulation material, which is quite difficult in the construction process of the external wall and internal wall thermal insulation project, and it is not easy to be installed on the wall. the danger of
