Problems solved by technology

[0002] Floor glue is an adhesive specially used for bonding wooden floors. It is mainly used to fit the panels and bottom plates of wooden floor substrates. Most wooden floors on the market use urea-formaldehyde and phenolic glues, which are prone to deformation of wooden floors. Cracks appear on the floor, reducing the life of the wooden floor
The high formaldehyde content in urea-formaldehyde and phenolic glues is harmful to human health, and there are some inherent defects in urea-formaldehyde and phenolic glues, such as poor storage stability and long curing time.

Embodiment 1

[0037] 1) Put 60kg of water-based polyester polyurethane and 0.8kg of water-based wetting and dispersing agent (model ECODIS P50) in the stainless steel container of the high-speed disperser, turn on the disperser, control the speed at 300r / min, and after dispersing for 6 minutes, add 10kg Filler (calcite powder), increase the speed to 700r / min for high-speed dispersion, then add 0.3kg of defoamer (model YMT-322), after dispersing for 25min, add 15kg of water-based hydroxyacrylic resin (model YPWA-22W02), 7kg of styrene-butadiene latex (model TG201) and 0.8kg of powder thickener (model BENTONE DE) were uniformly dispersed to obtain a preliminary slurry, and the viscosity of the preliminary slurry was controlled to 40,000 mPa.s.

[0038] 2) Add 3.5kg of curing agent (amino resin crosslinking agent) to the prepared slurry before use, and disperse evenly to obtain water-based composite solid wood multi-layer floor glue.

Embodiment 2

[0040] 1) Put 65kg of water-based polyester polyurethane and 1.0kg of water-based wetting and dispersing agent (model BFK-1600W) in the stainless steel container of the high-speed disperser, turn on the disperser, control the speed at 300r / min, and after dispersing for 6 minutes, add For 12kg of filler (wood powder), increase the speed to 800r / min for high-speed dispersion, then add 0.3kg of defoamer (model Defom W-052), and after dispersing for 25min, add 12kg of water-based hydroxyacrylic resin (model YPWA-22W02 ), 8kg of styrene-butadiene latex (model SD417) and 1.0kg of powder thickener (model BENTONE DE), uniformly dispersed to obtain a preliminary slurry, the viscosity of the preliminary slurry is controlled to 42,000 mPa.s.

[0041] 2) Add 4.0kg of curing agent (amino resin crosslinking agent) to the prepared slurry before use, and disperse evenly to obtain water-based composite solid wood multi-layer floor glue.

Embodiment 3

[0043] 1) Put 68kg of water-based polyester polyurethane and 0.7kg of water-based wetting and dispersing agent (model ECODIS P50) in the stainless steel container of the high-speed disperser, turn on the disperser, control the speed at 300r / min, and after dispersing for 6 minutes, add 14kg Filler (calcite powder), increase the speed to 700r / min for high-speed dispersion, then add 0.5kg of defoamer (model YMT-322), after dispersing for 25min, add 10kg of water-based hydroxyacrylic resin (model 8300), 9kg of Styrene-butadiene latex (model SD417) and 1.0kg of powder thickener (model BENTONE DE) are uniformly dispersed to obtain a preparatory slurry, and the viscosity of the preparatory slurry is controlled to 40,000 mPa.s.

[0044] 2) Add 4.5kg of curing agent (polycarbodiimide) to the prepared slurry before use, and disperse evenly to obtain water-based composite solid wood multi-layer floor veneer glue.

Abstract

The invention provides waterborne composite solid wood multi-layer floor bottom plate and face plate adhesion glue and a production technology thereof. The waterborne composite solid wood multi-layer floor bottom plate and face plate adhesion glue is prepared from the following raw materials in parts by weight: 60 to 75 parts of waterborne polyester type polyurethane, 6 to 15 parts of waterborne hydroxyl acrylic resin, 5 to 10 parts of styrene-butadiene latex, 8 to 16 parts of filler, 0.5 to 1.0 part of a wetting dispersant, 0.1 to 2.0 parts of a defoamer, 0.5 to 2.0 parts of thickener powder and 0.3 to 6.0 parts of a curing agent. According to the waterborne composite solid wood multi-layer floor bottom plate and face plate adhesion glue provided by the invention, the adhesion strength of plates can be increased through the waterborne polyester type polyurethane, meanwhile, the hardness and the water resistance of the plates are increased through the addition of the waterborne hydroxyl acrylic resin, the elongation rate and the rebound elasticity of the waterborne composite solid wood multi-layer floor bottom plate and face plate adhesion glue are increased through the added styrene-butadiene latex, and the three kinds of resin have groups to react with the curing agent, so that the water resistance can meet a first-stage index of JAS (Japanese Agricultural Standard); the waterborne composite solid wood multi-layer floor bottom plate and face plate adhesion glue is used for adhering a face plate and a bottom plate of a solid wood composite floor base plate, the plates are not easy to warp upwards and bend downwards, and the problem that the plates are easy to deform and crack can be avoided.
