Abstract
The invention relates to a double-component polyurethane foaming adhesive for buildings. The foaming adhesive is dedicated for adhering polystyrene board (EPS), cement board (GRC) and extruded sheet (XPS) internal and external wall insulation boards. The double-component polyurethane foaming adhesive has controllable adhering time and has temperature resistance, cold resistance, hydrolysis resistance and strong adhesive power. When the double-component polyurethane foaming adhesive is adhered to the wall, a user can loose hand in time to assemble a fastener. Compared with the conventional adhesive, the double-component polyurethane foaming adhesive saves working hours and cost, also relates to energy saving of a building system and greatly reduces waste generated in the constructing process. A material of the invention is formed by mixing an A adhesive (a white material) with a B adhesive (a black material). The range of the mass ratio of the A adhesive to the B adhesive is wide. 100 parts by mass of A adhesive and 50 to 70 parts by mass of B adhesive can be attached and do not influence the bonding strength. The double-component polyurethane foaming adhesive can be operated in harsh environment of low temperature between minus 3 DEG C and 5 DEG C, but the walls must be dried. The A and B adhesives can be bonded after being mixed precisely and stirred uniformly. Under the condition that the wall is not flat slightly, microfoam of the double-component polyurethane foaming adhesive of the invention can help to fill in gaps between the boards and the wall to make the inside generate an isolation layer to more achieve the effects of insulating heat and preserving heat.
Description
Technical field
The invention belongs to building material technical field, relate to the polyurethane two-component foaming adhesive of used for adhering internal wall and external wall in a kind of building, the especially a kind of XPS in the building, dual-component polyurethane foamed glue of EPS warming plate binding cement body of wall of being exclusively used in.
Background technology
In recent years, along with the continuous propelling of Chinese architecture energy conservation, the development of External Thermal Insulation Technology for External, the present constructional method that generally adopts cement, EPS or XPS is at exterior wall processing paste heat-preserving laminate.Adhesive material adopts clay, linked network, nailing or the like more, and these adhesive materials its intensity rising setting time when construction is long, and its shortcoming is summarized as follows:
(1) generally use clay and epoxy type glue, bonding overlong time must be at 3 hours, and other clay just can reach certain intensity later on about 24 hours.Need a large amount of cement, mortar etc. during construction, when building high-rise building, it is consuming time that material is too much carried, and working efficiency is poor.
(2) the two component glue of above-mentioned epoxy cost an arm and a leg, and general clay drying, gel time are long, and intensity can't in time be come up, and causes construction not convenient, increases more cost of labor.
Summary of the invention
The object of the present invention is to provide a kind of dual-component polyurethane foamed glue, at benzene plate (EPS), extruded sheet (XPS), cement plate (GRC) and the special adhesive of exploitation.To solve shortcomings such as waste of material that conventional adhesive exists, complex procedures, contaminate environment, bonding force difference, dual-component polyurethane foamed glue of the present invention, controlled, heatproof of its stickup time, cold-resistant, hydrolysis, intensity height, strong adhesion, therefore the stickup condition of this glue is loose, has saved man-hour and cost.
Dual-component polyurethane foamed glue of the present invention is made up of A glue (little Huang) and B glue (tawny), and A glue and B glue are respectively urethane (polyol) polyether glycol combination formula and isocyanic ester (ISO) prescription, also can be called white material and black material respectively.The ratio range of A/B is wide, and proportioning can both be fitted between 50～70 parts in B glue in 100 parts in A glue, does not influence its bonding strength, and can still can operate under the low temperature between-3 ℃～5 ℃.During use, A glue and B glue are by the deal proportioning of index, and brushing can be bonded in metope on sheet material after evenly stirring.The little foaming of this adhesive tape has under the irregular situation slightly at body of wall, and little foaming can be filled up the gap of body of wall and sheet material, more can reach the effect of insulation, disconnected heat.
The white material of dual-component polyurethane foamed glue of the present invention and black material each component weight ratio prescription are as follows:
Polyether glycol 60% polyoxyethylene glycol 18%
Sorbyl alcohol 8% magnesium hydroxide 6%
1.4-two Zhong Ding amino-benzenes 1% 1.8 diazacyclo hendecenes 0.2%
