Description
Technical Field
The application relates to a high-strength boiling water-resistant bi-component plate splicing adhesive, and a preparation method and application thereof, and belongs to the technical field of building materials.
Background
Formaldehyde is a relatively high toxic substance, and is on the 2 nd place of the preferential control list of toxic chemicals in China. The adhesive and its products can release formaldehyde and other harmful substances during production and use, causing air pollution in workshops and rooms and harming human health. Along with the deeper and deeper understanding of people on the indoor formaldehyde hazard, the requirements of various countries in the world on the formaldehyde release of the artificial board are stricter, and in order to provide a healthy and nontoxic indoor environment for consumers, the market actively tries to use a formaldehyde-free adhesive.
In the middle of the last 60 s, people began to pay attention to the harm of formaldehyde, and the applications of prepared rehmannia root in wood industry production are mainly classified into three major types, namely polyvinyl acetate emulsion (white latex) adhesive, water-based vinyl polyurethane adhesive (EPI adhesive) and soybean protein-based adhesive, wherein the polyvinyl acetate emulsion adhesive is widely known. The white latex has poor water resistance and low temperature resistance, and is mainly applied to occasions with low requirements, such as woodworking press plates and the like. The soybean protein-based adhesive has poor water resistance, low strength and easy mildew formation, and is mainly applied to the field of plywood. Meanwhile, part of the white latex and the soybean gum still contain formaldehyde, so that the environment-friendly soybean gum is not really environment-friendly and non-toxic. The EPI glue is really zero in formaldehyde addition and is widely applied to jointed boards of laminated wood, furniture and the like. The wood splicing glue is an adhesive for splicing wooden products such as laminated wood and the like. With the rapid development of urban building and decoration industry in China, the requirements of people on the application of glue for laminated wood in recent years are continuously refined, whether the price or the operation is cheaper and simpler, the glue in the domestic market at present can pass the LY/T1601-2011 standard for soft and hard woods such as pine, fir, white birch and the like, but the glue in the domestic market for materials such as northeast China ash, beech, bamboo chips and the like passes the standard or has the price higher than 15 yuan-20 yuan/kg, and meanwhile, the problems of short glue active period, high viscosity, difficulty in coating and the like can occur in the operation process, so that the development of EPI plate glue which has low price and long active period and meets the requirement of LY/T1601-2011 repeated boiling water has important significance.
Application number 201110007246.8 discloses a high-strength plate alignment adhesive, which mainly comprises the following components: 30-40% of EVA (industrial grade) emulsion, 15-20% of carboxylic styrene-butadiene emulsion, 15-30% of triple superphosphate, 0.04-0.07% of defoamer, 15-20% of PVA (polyvinyl alcohol), 20-30% of water, 0.06-0.12% of dispersant, 0.1-0.2% of plasticizer, 0.08-0.12% of wetting agent and 0.04-0.07% of bactericide. The invention has the advantages of high bonding strength, excellent heat resistance and water resistance, low viscosity, easy coating, long adaptation period, high curing speed and low cost. The plate alignment adhesive prepared by the method adopts the butylbenzene emulsion as an auxiliary base material, and is compounded with the curing agent MDI for use, so that the price is high, the environment is not protected, and the product is easy to layer.
Application number 201210452661.9 discloses a high-strength two-component plate alignment adhesive and a preparation method thereof, and the high-strength two-component plate alignment adhesive mainly comprises 40-60% of vinyl acetate emulsion, 2-4% of polyvinyl alcohol, 1-5% of functional monomer, 0-1.5% of plasticizer, 15-25% of inorganic filler, 0.05-0.2% of dispersant, 0.05-0.2% of defoamer, 0.05-0.2% of bactericide, 5-30% of deionized water, and a curing agent PAPI. The invention does not contain organic solvent, and has high strength and good water resistance. The invention adopts the vinyl acetate emulsion as the matrix and the PAPI as the curing agent, has high cost and is not suitable for commercial use.
Application number 201710127663.3 discloses a high-strength laminated wood splice glue, which mainly comprises 25-35% of vinyl chloride emulsion, 10-20% of carboxylic butylbenzene emulsion, 3-8% of EVA emulsion, 15-25% of triple superphosphate, 0.1-0.3% of defoaming agent and 20-30% of PVOH aqueous solution. 0.1 to 0.3 percent of dispersant, 3 to 5 percent of film-forming additive, 0.3 to 0.5 percent of wetting agent and 0.1 to 0.3 percent of bactericide. Aiming at splicing high-grade hard redwood furniture plates, the invention has the advantages of easy coating, long adaptation period, high curing speed, convenient and efficient construction, low cost and environmental protection. The invention mainly meets the I-type and II-type standards of the plate alignment adhesive, namely the compressive shear strength under hot water immersion, does not meet the index of boiling water resistance, and has narrow application range.
At present, polyvinyl acetate emulsion, styrene-butadiene emulsion, styrene-acrylic emulsion and the like are generally used as matrixes in the market, polyvinyl alcohol is used as protective colloid, and the prepared plate alignment adhesive has the problems of high price, short opening time, boiling water resistance and the like.
