Abstract

The invention discloses a thermal insulation board special for a building. The thermal insulation board comprises the following raw materials in parts by weight: 20-30 parts of polyurethane, 10-20 parts of foamable polystyrene, 15-30 parts of fly ash, 8-19 parts of modified bentonite, 12-27 parts of expanded vitrified microbeads, 6-11 parts of dispersible latex powder, 2-4 parts of polypropylene fiber, 1-3 parts of cloth fiber, 2-3 parts of sodium carboxymethyl cellulose, 1-2 parts of a waterproof agent and 1-3 parts of a flame retardant. According to the thermal insulation board special for the building, by controlling the types of raw materials and the proportions of the raw materials, the prepared product has the advantages of low water absorption, good durability, good thermal insulation effect, good fire resistance and no threat to human life and safety.

Description

technical field [0001] The invention belongs to the technical field of energy-saving products, and in particular relates to a special thermal insulation board for buildings and a preparation method thereof. Background technique [0002] Thermal insulation is the most important energy-saving measure in building energy conservation. At present, there are many types of thermal insulation materials in my country, but there are generally problems of high water absorption, poor durability or flammability, and poor fire resistance. The former greatly reduces the thermal insulation performance of thermal insulation materials. It affects the effect of thermal insulation and increases the energy consumption of the air conditioning system, which will pose a threat to human life and safety. Contents of the invention [0003] The invention provides a thermal insulation board for building and its preparation method, which solves the problems in the background technology. The thermal insu...
