Problems solved by technology

However, in practical applications, they are usually not used alone, but are made into hard block products or thermal insulation mortar with a certain shape through the bonding of inorganic gelling materials. Due to the high thermal conductivity of inorganic gelling materials, The thermal insulation performance of the final expanded perlite product drops sharply; in addition, the high water absorption of the product is also a problem that must be solved for this type of material. In the process, the bubble body will inevitably be damaged, making the hydrophobic treatment invalid and further reducing the thermal insulation performance.

Embodiment 1

[0020] 16g of expanded vitrified microbeads with an average particle diameter of 0.1mm are surface-activated with 0.5g of silane coupling agent γ-(methacryloyloxy)propyltrimethoxysilane, and then the expanded vitrified microspheres are mixed with 60g Polyurethane A material (polyisocyanate composite material) is mixed, after mixing evenly, then add 50g of polyurethane B material (polyether polyol composite material) and mix, after mixing uniformly, cast, obtain the hard foam of the present invention after molding Polyurethane-expanded vitrified microbead composite thermal insulation and flame retardant board. Or further, cut it according to the needs of use.

Embodiment 2

[0022] First, 32g of the expanded vitrified microspheres with an average particle diameter of 0.5mm were used with 0.16g of silane coupling agent

[0023] γ-(Methacryloyloxy)propyltrimethoxysilane is used for surface activation, and then the expanded vitrified microspheres are mixed with 50g of polyurethane material B. After mixing evenly, 60g of material A polyurethane is added for mixing. After casting and molding, the rigid foam polyurethane-expanded vitrified microsphere composite thermal insulation and flame-retardant board of the present invention is obtained.

Abstract

The invention discloses a hard-foam polyurethane-expanded and vitrified microbead composite heat insulation flame-retardant board and a preparation method of the flame-retardant board, wherein the hard-foam polyurethane-expanded and vitrified microbead composite heat insulation flame-retardant board takes an expanded and vitrified microbead as a dispersed phase, and takes polyurethane material A and polyurethane material B as a continuous phase. The heat insulation flame-retardant board has the characteristics of good heat insulation effect and superior flame retardant property.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a hard foam polyurethane-expanded vitrified microsphere composite thermal insulation and flame-retardant board and a preparation method thereof. Background technique [0002] With the development of society, the requirements for buildings are getting higher and higher. In addition to the requirements of building quality and aesthetics, the thermal insulation performance of buildings is also one of the most important requirements. In today's society, the energy consumption of buildings accounts for a considerable proportion of the total energy consumption of the society. The energy consumption of buildings is mainly the energy consumption of temperature regulation. Under the social development trend of energy saving and emission reduction, it is of great significance to improve the thermal insulation performance of buildings and reduce the energy consumption of buildi...
