Problems solved by technology

In recent years, some manufacturers have also used white latex water-based adhesives for compounding. White latex is relatively environmentally friendly, but the compound fastness is not enough. After 24 hours of compounding, the adhesive layer will be destroyed after 1 hour of boiling water test.
The XPS extruded board can be pre-treated on the composite surface to enhance the surface roughness and increase the surface tension. After

Abstract

The invention relates to the technical field of aqueous adhesives, and more particularly relates to an aqueous adhesive for compounding aluminium foils with extruded polystyrene (XPS) boards and a preparation method thereof. The formulation of the aqueous adhesive comprises 77-110 parts of deionized water, 0.4-1.5 parts of a phosphate emulsifier, 50-60 parts of an acrylics monomer mixture, 5-12 parts of reactive phosphate functional monomer, 0.2-0.8 parts of an initiator, 0.05-0.15 parts of a thickener, 0.05-0.2 parts of a defoamer and 0.02-0.05 parts of a wetting agent, which are polymerizedby a special process for preparing the aqueous adhesive. The aqueous adhesive prepared by the invention has strong adhesion on the aluminium foils and greatly improves the bonding strength with base materials. After applied to the compounding adhesion between the aluminium foils and the XPS boards and further dried and cured for 24 hours, the aqueous adhesive enables the XPS board to be soaked inboiled water for 1 hour without no damage to the bonding layer.

Description

technical field [0001] The invention relates to the technical field of water-based adhesives, in particular to an aluminum foil XPS extruded board composite water-based adhesive and a preparation method thereof. Background technique [0002] In recent years, my country has placed great emphasis on creating an energy-saving and environmentally-friendly society, formulating and implementing very strict building energy-saving design standards in terms of building energy conservation, and vigorously promoting new wall materials and energy-saving products. XPS extruded board has a honeycomb closed-cell structure, is airtight and water-proof, has good heat insulation, waterproof and moisture-proof effects, and is light in texture and high in strength. It has excellent indicators that ordinary boards cannot achieve. In addition, aluminum foil has the title of "super heat insulating material", with small emissivity (that is, small absorptivity and high reflectivity), relatively smal...
