Problems solved by technology

There are following defects in the prior art: the one, mostly be on-the-spot construction (promptly on-the-spot sprays polyurethane material to the roof, then sticks or coats waterproof layer), and can only be constructed on a horizontal plane or an approximate horizontal plane, and for the construction vertical to the horizontal plane The surface construction of the wall is very difficult, and the thickness and uniformity of the polyurethane insulation layer are difficult to guarantee; the second is to spray the polyurethane insulation layer on site, which is greatly affected by the base and environmental factors. Requirement; The 3rd, prior art is only done waterproof treatment to one side surface of polyurethane thermal insulation layer, and the other side surface still absorbs water from roofing layer (being cement mortar) in construction, and reduces its thermal insulation effect

Embodiment 1

[0025] As shown in Figure 1, a waterproof layer 2 is provided on one side surface of the polyurethane insulation board 1, and a waterproof adhesive layer 3 and an easy-to-paste layer 4 are successively provided on the side surface, and the waterproof adhesive layer 3 is selected from VAE emulsion and Auxiliary materials (white cement, calcium carbonate, plasticizer and other materials) are used to make waterproof coatings. The easy-to-stick layer is made of non-woven fabric. The waterproof layer 2 is made of plastic waterproof coiled material.

[0026] The preparation process of polyurethane waterproof and easy-to-paste thermal insulation composite board is as follows:

[0027] (1) First apply a waterproof coating made of a waterproof adhesive layer VAE emulsion and auxiliary materials on the surface of the easy-to-stick layer, that is, one side of the non-woven fabric, to obtain a waterproof and easy-to-stick composite layer, and roll it on the shaft after drying;

[0028] ...

Embodiment 2

[0031] As shown in FIG. 2 , a waterproof adhesive layer 3 and an easy-to-stick layer 4 are sequentially arranged on both sides of the polyurethane insulation board 1 . The shaft roll of the waterproof and easy-to-paste composite layer obtained in step (1) in Example 1 is placed on the shelf at the inlet end of the foaming box, and the waterproof and easy-to-paste composite layer is pulled out (this side of the waterproof adhesive layer faces upwards) ), spread it flat on the walking plane at the inlet end of the foaming and curing box, and spray polyurethane material on the surface with a spray gun. All the other implementations are as in Example 1.

Embodiment 3

[0033] As shown in Figure 3, a waterproof adhesive layer 3 and an easy-to-stick layer 4 are sequentially provided on one side of the polyurethane insulation board 1, and a waterproof adhesive layer 3, an easy-to-stick layer 4, and a waterproof layer 2 are sequentially provided on the other side surface. . The double-side surfaces of the polyurethane thermal insulation board 1 obtained in Example 2 are successively provided with a waterproof adhesive layer 3, an easy-to-stick layer 4 and a heat-insulating composite board, and then one side of the easy-to-stick layer 4 is coated with a waterproof paint (VAE emulsion can be selected for use). Waterproof coating made with auxiliary materials) can be.

Abstract

The invention discloses a polyurethane waterproof adhesive heat-insulating composite board and the manufacturing method thereof, which includes a polyurethane heated board, wherein the surfaces at both sides of the polyurethane heated board are sequentially provided with a waterproof binding course and an adhesive course; or the surface of one side is sequentially provided with a waterproof binding course and an adhesive course while the surface of another side is sequentially provided with a waterproof course; or the surface of one side is sequentially provided with a waterproof binding course and an adhesive course while the surface of another side is sequentially provided with a waterproof binding course, an adhesive course and a waterproof course. The invention is manufactured in serials through the factory, and the foaming and aging of the polyurethane heated board are both finished in a thermostatic equipment, furthermore, the bonding and compositing of the waterproof course and the adhesive course at both sides are also finished simultaneously during the process. The invention has excellent heat-insulating property, high cohesive strength with the wall and is simple and convenient for construction.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to thermal insulation and waterproof materials in building materials. Background technique: [0002] At present, energy has become a bottleneck restricting the sustained and rapid development of the national economy, and building energy consumption accounts for about 30% of the total energy consumption, and there is an upward trend, so building energy conservation has become an urgent matter. In recent years, the building material industry has introduced many energy-saving materials. Among them, the polyurethane thermal insulation composite board is favored by the market because of its light weight and good thermal insulation effect. It is used for roof insulation or indoor wall, roof, and ground insulation. No. ZL98027206.6 discloses "Integral Spraying Rigid Polyurethane Foam Waterproof and Insulated Composite Roof", Patent No. ZL200420099060.5 discloses "rigid polyurethane foam ...
