Description

A rigid foam polyurethane thermal insulation and decoration integrated board

technical field

The utility model relates to the design category of an external thermal insulation structure of an exterior wall, in particular to a hard foam polyurethane thermal insulation and decoration integrated board. the

Background technique

With the continuous advancement of my country's energy-saving policy, more and more attention has been paid to the external thermal insulation of building exterior walls, and the external thermal insulation structure of external walls has gradually matured. At present, the external wall insulation structure commonly used in my country is mainly composed of adhesive layer, insulation layer, bottom layer, reinforcement layer, surface layer and finishing layer. The insulation layer is mainly made of organic insulation materials such as hard foam polyurethane and EPS or It is composed of inorganic insulation materials such as porous rock wool and mineral wool. These thermal insulation materials either have good thermal insulation performance, but the combustion level is not high, and the fireproof performance is not good; or the fireproof performance can reach Class A, but the thermal insulation performance is not ideal. EPS is one of the most widely used thermal insulation materials since my country has thermal insulation systems. Its construction technology is mature and its thermal insulation effect is good. However, due to the flammability of EPS, after several fires, the Fire Department of the Ministry of Public Security issued a document No. 350, Strict restrictions on the use of flammable and combustible insulation materials such as EPS have been made; the fire performance of inorganic insulation materials such as porous rock wool can reach Class A, but it is easy to absorb water. After absorbing water, the insulation performance is seriously reduced, and the mechanical properties are also affected accordingly. With the continuous improvement of technical requirements in the field of external thermal insulation of building external walls, the market needs an external thermal insulation structure of external walls that combines excellent fireproof thermal insulation performance and decorative performance. the

Contents of the invention

The purpose of this utility model is to propose a rigid polyurethane foam thermal insulation and decorative integrated board, which can combine fireproof thermal insulation and decorative performance, and the bonding strength of the composite board is greatly improved. the

The technical solution of the thermal insulation board is: a rigid foam polyurethane thermal insulation and decoration integrated board, including: cement glass fiber cloth, rigid foam polyurethane, porous cotton board, and decorative board; the rigid foam polyurethane is combined with the porous cotton board by pouring One side is connected, and the rigid polyurethane foam poured into the hole of the porous cotton board forms an integrated structure with the rigid polyurethane foam poured out of the hole of the porous cotton board; the other side of the porous cotton board is bonded with a decorative board, and the hard foam polyurethane The other side of the polyurethane foam board is bonded with cement fiberglass cloth. the

Further, the porous wool board is a rock wool board or a glass wool board provided with through holes. the

Further, the through hole is circular with a diameter of 4-6cm. the

Further, the decorative board is based on a calcium silicate board. the

Further, the thickness of the rigid polyurethane foam board is 3-6cm. the

Further, the thickness of the porous cotton board is 2-5cm. the

The advantages of rigid foam polyurethane and porous cotton insulation and decoration integrated board are:

1. The board is a composite thermal insulation board made of porous cotton and rigid polyurethane foam. The outer layer has a decorative board based on calcium silicate board, which has both fireproof and thermal insulation performance and decorative performance. It can be widely used in the external thermal insulation system of building exterior walls to meet the requirements of fire retardant, energy saving and thermal insulation

2. Different from ordinary rock wool boards, the cotton boards used in this insulation and decoration integrated board have holes punched manually in the later stage. The purpose is that when the polyurethane is poured, it can form a wedge-like effect, which can make the hard foam polyurethane board and the pouring The hard foam polyurethane in the hole has an integrated structure, so that the bonding strength between the hard foam polyurethane and the porous cotton is greatly improved.

3. The shape, size, quantity, and plane distribution of the holes punched on the cotton board can be adjusted according to actual production and different requirements for product performance, and products with different strength levels can be obtained, and the product has a wider range of applications. the
