Embodiment 1

[0034] Embodiment 1: A kind of modified polyurethane material, preferably it is made of the following raw materials by weight: 60 parts of aromatic polyester polyols; 55 parts of foaming agent (cyclopentane); foam stabilizer (polyether modified 0.3 parts of dibutyltin oxide; 12 parts of melamine; 20 parts of flame retardant (TCPP); Diamine) 55 parts.

[0035] The filler is one or a combination of glass microspheres, diatomaceous earth, calcium carbonate, vitrified microspheres, and wood chips.

[0036] Energy-saving panels for exterior wall decoration containing the above-mentioned modified polyurethane materials, such as figure 1 , figure 2 As shown; including the base layer 5, the decoration layer 1, the thermal insulation and flame-retardant layer 4 wrapped between the base layer 5 and the decoration layer 1, the base layer 5 and the decoration layer 1 are all made of the above-mentioned modified polyurethane material, The thermal insulation and flame-retardant layer is...

Embodiment 2

[0051] Example 2, the same as Example 1 will not be stated, the difference is: the reinforcement layer is a fishing net, and the components and parts by mass of the modified polyurethane are: 55 parts of aromatic polyester polyol: 45 parts of cyclopentane; 2 parts of polyether modified silicone; 0.2 part of dibutyltin oxide; 11 parts of melamine; 1 part of TCPP; 230 parts of methane diisocyanate; 50 parts of triethylene diamine.

Embodiment 3

[0052] Example 3, the same as Example 1 will not be stated, the difference is: the reinforcement layer is a reed mat or a bamboo net, and the components and parts by mass of the modified polyurethane are: aromatic polyester 65 parts of polyol: 65 parts of cyclopentane; 4 parts of polyether modified silicone; 0.4 parts of dibutyltin oxide; 13 parts of TCPP; 25 parts of flame retardant; 160 parts of microbeads or sawdust; 250 parts of methane diisocyanate; 60 parts of triethylene diamine.

Abstract

The invention discloses a modified polyurethane material, an exterior-wall decorative energy-saving plate and a preparation method thereof, aims at solving technical problems that the existing decorative thermal-insulation plate is heavy, water-funk, inflammable, easy to crack, easy to drop and complex in construction. The modified polyurethane comprises the following components: polyester polyol, a foaming agent, a foam stabilizer, tin dibutyl, melamine, a flame retardant, glass beads, isocyanate and a catalyst; the exterior-wall decorative energy-saving plate made of the polyurethane comprises a base layer, a decorative layer and a thermal-insulation flame-retardant layer packaged between the base layer and the decorative layer; and the production method of the exterior-wall decorative energy-saving plate comprises seven steps. The exterior-wall decorative energy-saving plate produced by the preparation method in the invention has the advantages of being good in decorative effect, thermal-insulation, fireproof, waterproof, high in strength, un-cracked, long in service life, simple to construct, and the like.

Description

technical field [0001] The invention specifically relates to a modified polyurethane material, an energy-saving panel for exterior wall decoration and a preparation method thereof. Background technique [0002] In recent years, fires of exterior wall insulation materials have occurred frequently, causing heavy casualties and property losses. Therefore, with the comprehensive advancement of building energy conservation, building energy conservation and fire prevention issues have been paid more and more attention by people; with the further standardization of modern building fire prevention, energy conservation, and environmental protection requirements, non-fireproof insulation materials have been gradually banned by the state. [0003] When people are beautifying and adorning the exterior walls of buildings, they mostly adopt materials such as ceramic tiles and marble faces on the exterior walls. Due to the heavy weight of the above-mentioned materials, and it is not easy ...
