Micro powder reinforced polyurethane-based high-strength waterproof heat preservation and decoration integrated material and preparation method thereof

Abstract

The invention relates to a micro powder reinforced polyurethane-based high-strength waterproof heat preservation and decoration integrated material and a preparation method thereof. According to the material, polyurethane is adopted as matrix resin, a large number of micro powder particles and multiple compounding agents are added, grinding is carried out, foaming is controlled, and the closed-cell material is prepared. Coatings or rolls or plates or blocks can be manufactured by means of brushing or spraying or pouring. The material can be manufactured to be red, yellow, blue, black, white and other colors by adjusting a coloring agent. The material has the comprehensive advantages of being efficient, waterproof, good in heat preservation performance and decoration effect, high in strength, good in corrosion resistance, resistant to inflaming and the like. The coatings are tightly bonded with a substrate, and the surface is smooth. The material has good toughness as the rolls and can be used for waterproofness and heat preservation of newly-built or existing buildings, tunnels, underground facilities and the like. The material serves as the plates, sand particles can be bonded to the surface of damp-dry slurry to obtain various building plates with a stone grain decoration effect. The material is extremely low in cost and has good market prospects.

Description

technical field [0001] The invention relates to a micropowder-reinforced polyurethane-based high-strength waterproof heat preservation and decoration integrated material and a preparation method thereof. Background technique [0002] In recent years, real estate has developed vigorously. With the improvement of people's requirements for building energy saving, safety and environmental protection, the research and development of building waterproof and thermal insulation materials has become an important topic in the construction industry. my country is a country with large building energy consumption. The energy consumption per unit area of ​​heating is equivalent to 2 to 3 times that of countries with similar climate conditions. Building energy consumption has accounted for 1 / 3 of the total energy consumption of the society. Building energy conservation has a long way to go. In addition, modern buildings require waterproof How to solve the waterproof problem of buildings fro...

AI Technical Summary

Problems solved by technology

[0003] (1) The waterproof and thermal insulation of existing building materials are usually not well balanced. Generally, organic building materials with good thermal insulation effect have high porosity and high water absorption rate, and their waterproof performance is greatly reduced, and their fire protection rating is low.

Generally, organic building materials with good waterproof effect have low strength and are easily damaged, which cannot meet the needs of modern buildings for integrated materials with high strength and long-term efficient waterproof and thermal insulation

[0004] (2) During the construction of the existing waterproof layer, a wide variety of materials are required, and multiple constructions are required, and the process is complicated

In addition, the cost of most waterproof layers is high, and the cost is about 80-110 yuan / ㎡

[0005] (3) When the existing thermal insulation material adopts inorganic materials, it shows the defects of high water absorption rate, easy cracking, easy water seepage and poor thermal insulation and waterproof effect during use

Although this type of organic thermal insulation material has the characteristics of small thermal conductivity and good thermal insulation performance, its fireproof performance is poor and cannot meet high fireproof standards.

[0007] (5) Due to the low degree of integration of the construction process, cracks of different degrees often appear on the window sills, columns, beams, etc. of the exterior walls of the building. During the maintenance and use process, these cracks will expand and deepen, which will lead to the destruction of the thermal insulation and waterproof system.
