Embodiment 1

[0020] 1. Preparation of white material:

[0021] Step 1: Take 50% polyether polyol and other raw materials to polymerize first, and stir at a high speed at a normal temperature of about 25-30°C.

[0022] Step 2. Add triethylene ditertiary amine as initiator and catalyst, propylene glycol triol as surfactant and other remaining materials in proportion to the polymerization product of step 1, heat to 50° C., and stir for about 2 hours.

[0023] Step 3, cool the white material prepared in step 2, and then store it in a sealed barrel.

[0024] 2. Preparation of black material (ISO):

[0025] Step 1, put 85% polymethylene phenyl isocyanate, 10% modified polyol diphenylmethane diisocyanate and 5% plasticizer (aliphatic diacid ester) into the container.

[0026] Step 2: Heat the raw materials in step 1 to 50°C-60°C and stir, react first and then cool.

[0027] 3. When using, mix the prepared white material and black material uniformly in a weight ratio of 1:0.5 to 1:1.1.

Abstract

The invention relates to polyurethane two-component foaming adhesive used for the building to adhere boards, metal, glass, marble, polystyrene boards, extruded boards (XPS), polyurethane boards, cement boards and other materials. The polyurethane two-component foaming adhesive has controllable adhering time, high strength and strong adhesive power, can resist heat, coldness and hydrolysis, does not need the fastener and can be directly adhered to the old wall to save the labor hour and the cost. The polyurethane two-component foaming adhesive is formed by mixing white adhesive A and fulvous adhesive B which have wide mass ratio range, and if being formed by 100 portions of adhesive A and 50-110 portions of adhesive B, the polyurethane two-component foaming adhesive can be still adhesive, can not be affected in the adhesive strength and can be operated between 3 DEG C below zero and 5 DEG C below zero. The adhesive A and the adhesive B can be proportioned accurately and can be adhesive after being stirred evenly. The polyurethane two-component foaming adhesive can be slightly foamed if the wall is slightly uneven so as to fill in the gap between the wall and the board and prevent the rainwater entering the gap to generate the isolating layer. The polyurethane two-component foaming adhesive can achieve better effect of insulating heat.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a two-component polyurethane foam glue used for laminating interior and exterior walls in buildings. Background technique [0002] In recent years, with the continuous advancement of China's building energy-saving work, external wall insulation technology has developed vigorously as an important building energy-saving technology in China. The construction method of the thermal insulation wall generally adopted at present is to paste the thermal insulation laminate on the external wall processing, and the pasting materials are mostly cement, white glue, epoxy two-component glue, etc. However, the strength of these pasting materials increases during construction and the hardening time is too long. During the lamination process, fasteners must be used to fix them first to avoid loosening. The disadvantages are summarized as follows: [0003] (1) The bonding t...
