Abstract

The invention discloses a long-active-period low-temperature-resistant water-based two-component plate splicing adhesive. The two-component water-based plate splicing adhesive is prepared from a mainagent and a curing agent according to the mass ratio of 100: (10-15), wherein the main agent is obtained by uniformly mixing the following components (by mass): 20-30 parts of a styrene-butadiene emulsion, 20-30 parts of a polyvinyl alcohol aqueous solution with the mass concentration of 20-30%, 20-25 parts of a VAE emulsion, 25-30 parts of calcium carbonate, 1-3 parts of a compound silane coupling agent, 0.5-1 part of a dispersing agent, 0.3-0.8 part of a wetting agent, 0.3-0.8 part of a defoaming agent and 0.5-1 part of a preservative. And the curing agent is an isocyanate curing agent. Thestyrene-butadiene emulsion and the compound silane coupling agent are added into the plate splicing adhesive, so that the cold resistance is greatly improved, the boiling water resistance is good, andthe shearing strength is higher; the compound-mesh calcium carbonate is added, and the total specific surface area is reduced, so that the long-activity-period performance of the two-component water-based plate splicing adhesive is achieved.

Description

technical field [0001] The invention belongs to the technical field of water-based glue for woodworking panels, and in particular relates to a two-component water-based glue with long active period and low temperature resistance. Background technique [0002] Water-based puzzle glue is a water-based adhesive, a special water-based emulsion, two-component, high solid content, high-strength adhesive, non-toxic, quick-drying, simple production process, high economic benefits, customers When in use, the equipment investment is small and the use is convenient. [0003] With the continuous improvement of people's material and cultural living standards, the requirements for furniture are getting higher and higher, and people's awareness of green environmental protection is constantly strengthening, so the jigsaw market is growing day by day, and the production range is wide. For this reason, there is an urgent need for water-based panel glue with low temperature resistance and lon...
