Abstract

The invention discloses a natural stone polyurethane heat-preserving waterproof heat-insulating integrated plate. The natural stone polyurethane heat-preserving waterproof heat-insulating integrated plate comprises a natural stone layer, a polyurethane foam layer and a waterproof interface layer; the natural stone includes granite and marble and is a base material, one surface is sprayed with the waterproof interface layer, and the waterproof interface layer is a polyvinyl formal layer, the waterproof interface layer is sprayed on the waterproof interface layer, and the thickness is 3-6 mm. Natural stone and waterproof heat-preserving and heat-insulating processing are integrated in the plate, and the plate is high in waterproof heat-preserving and heat-insulating performance and convenient to construct and is a novel roof building and ornament material with waterproof heat-preserving and heat-insulating functions. A heat bridge of an outer wall is omitted, so that the heat-preserving and heat-insulating effects are good, and the waterproof interface layer is sprayed and has the waterproof effect; the main body structure can be protected so that the outer wall structure can be in a relatively stable normal temperature status, cold and hot changes of the structure layer are avoided, temperature difference cracks are eliminated to the great extent, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a natural stone polyurethane heat-preservation, waterproof and heat-insulation integrated plate. 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, elegant and magnificent decorative effect and durable and wear-resistant excellent quality, which occupies a large proportion in decoration projects. Howeve...
