Embodiment Construction

[0073] see figure 1 As shown in the layered structure diagram of the natural stone PU waterproof insulation board of the present invention, a method for preparing a natural stone PU waterproof insulation board using polyurethane foam spraying technology, using natural stone 11 as the base layer, passing the component stock solution of rigid polyurethane through The sprayer mixes and rotates at high speed and impacts violently, forming fine mist droplets at the nozzle of the spray gun and spraying them evenly on the surface of natural stone. The polyurethane foams and solidifies to form a hard polyurethane foam layer 12. After curing, the hard polyurethane foam The surface of layer 12 is coated with waterproof interface layer 13 .

[0074] Described rigid polyurethane comprises following component by weight:

[0075] Polyether polyol based on o-toluenediamine 100 parts

[0076] Polymethylene polyphenylisocyanate 108 parts

[0077] Blowing agent 1,1-dichloro-1-fluoroethane 30...

Abstract

The invention relates to a novel waterproof insulation roof building material and preparation method thereof, in particular to a natural stone PU waterproof insulation board and method for preparing natural stone PU waterproof insulation board by applying polyurethane foam spraying technique. The natural stone PU waterproof insulation board takes natural stone as a basement layer; wherein hard polyurethane foam layer is arranged on one surface of the natural stone at least, and the surface of the hard polyurethane foam layer is covered with a waterproof interface layer. The invention provides a novel building material with both waterproof function and heat insulation function, the natural stone and waterproof and heat insulation processing are integrated, waterproof insulation performance is good, construction is convenient, and safety factor after construction is high, thus eliminating the heat bridge of outer wall at a large extent, which is impossible for inner heat insulation, being widely applied to energy conservation waterproof insulation in the building field and having a wide market prospect.

Description

technical field [0001] The invention relates to a new building material and a preparation method for roof waterproof and heat preservation, in particular to a natural stone PU waterproof and heat preservation board, and a method for preparing the natural stone PU waterproof and heat preservation board by applying polyurethane foam spraying technology. Background technique [0002] The purpose of exterior wall decoration is to improve the ability of the wall to resist the invasion and damage of various factors in nature such as dust, rain, snow, freezing, sun exposure, etc., and to meet the requirements of heat preservation, heat insulation, sound insulation, waterproof, etc. together with the wall structure. Beautification and other functional requirements. Therefore, the exterior wall decoration materials should take into account the dual functions of protecting the wall and beautifying the wall. Due to its natural color and variety, natural stone has a simple and elegant,...
