[0038] Wherein the polyether polyol is a mixture of polyoxyethylene ether and / or polyethylene glycol, such as starting from glycerin, copolymerized polyol of propylene oxide and ethylene oxide, random or end-capped copolymeriza...

Embodiment 2

[0048]The difference between this example and Example 1 is that the polyurethane thermal insulation structural adhesive in this example has a mass ratio of components A and B of 100:70, and component B is liquid MDI and 2,4'-MDI according to 1:1 mass ratio mixture. The manufacturing method step 1) is cooled and then solidified at room temperature for 20 seconds; in step 3), the material is poured into the groove of the aluminum profile moving at a speed of 0.35 m / s, and cooled and solidified for 20 hours. Obtain the polyurethane heat-insulating adhesive composite aluminum profile of straight shape.

Embodiment 3

[0050] The difference between this embodiment and the first embodiment lies in that the mass ratio of the components A and B of the polyurethane thermal insulation structural adhesive in this embodiment is 100:90.

Abstract

The invention discloses a polyurethane heat-insulation structural adhesive, which comprises components A and B, wherein the mass ratio of A to B is (90-110):(70-90); the component A comprises polyether polyol and auxiliaries; on the basis of the mass ratio of the auxiliaries to the polyether polyol, the auxiliaries comprise following components by weight percent: 0.1-0.3% of catalyst, 0.1-0.5% offlatting agent, 0.1-0.5% of de-foaming agent, 0.5-1.5% of chain extender, 0.1-5% of padding, 0.3-5% of plasticizer, 0.1-0.3% of anti-oxygen, and 0.1-0.3% of ultraviolet absorber; and the component B is isocyanate of MDI (methyl diphenylene diisocyanate) or TDI (toluene di-isocyanate). The invention also discloses a method for using the structural adhesive to prepare a heat-insulation aluminum profile. The polyurethane heat-insulation structural adhesive provided by the invention has advantages of excellent mechanical property, fatigue resistance, shock resistance, wear-resisting property, andstability. Room-temperature pouring and room-temperature solidifying processes are realized through the molding production; the pouring period is long; the molding production is not limited by temperature and the shape of aluminum profile; the operation is easily controlled; the rejection rate is low; and the molding production is beneficial to the popularization and application of the pouring type heat-insulation aluminum profile technique.

Description

technical field [0001] The invention relates to the technical field of building aluminum alloy profiles for aluminum alloy doors, windows and curtain walls, in particular to a polyurethane heat-insulating structural adhesive and a method for manufacturing the heat-insulating aluminum profiles. Background technique [0002] The issue of energy conservation and environmental protection has received more and more attention and attention in the world, and has occupied a vital position in social development. As people's awareness of environmental protection and energy saving continues to increase, many advanced energy-saving products and energy-saving processes have been gradually applied to various fields such as the construction industry. [0003] At present, there are mainly two types of heat-insulating aluminum alloy doors and windows for broken bridges and broken bridge heat-insulated aluminum profiles for curtain walls: "strip type" and "casting type". The strip-type heat-...
