Description
Technical field
The present invention relates to adhesive field, specifically a kind of two component polyurethane adhesive.
Background technique
In recent years, the compound indoor floor of PVC and WPC/SPC with its environmental-protecting performance and exempted from the advantage of glue installation in American-European city
Field is prevailing, and domestic similar product market has also started to rapidly develop, the trend that laminated flooring is replaced by PVC/WPC composite floor board
More see bright and clear.Because needing the surface for reducing WPC material using PE wax release agent that can or lead in the production process of wood moulding (WPC)
Cause WPC sheet surface uneven, the adhesive tape for being PVC and WPC carrys out certain difficulty.PVC/WPC compoiste adhering is most-often used
Adhesive be wet-solidifying single-component polyurethane hot melt adhesive (PUR, abbreviation polyurethane hot melt), the use of polyurethane hot melt is deposited
At (PUR cost of material is higher) at high cost, process conditions energy consumption high (needing constant temperature and humidity), (NCO refers to low isocyanate index
Number) and physical bond the disadvantages of causing bond effect unstable.
The substitute products of polyurethane hot melt are two component polyurethane adhesives, and two component polyurethane adhesive is to WPC's
Bond effect generally depends on WPC substrate surface treatment degree, always exists bond effect shakiness for the WPC plate without polishing
The disadvantages of fixed, colloid adhesive force fails, unit area glue-spread is too big.
Although the existing solvent-type double-component polyurethane binder in market improves the viscous of PVC and WPC to a certain extent
Effect is tied, but there is its solvent used pollution environment, Odor stimulation to endanger health, winter volatilizees, and low efficiency causes to bond
The disadvantages of agent bulk strength reduces, is high to the swelling extent of the destruction of equipment rubber roller, thus occupation rate of market is lower always.
