Problems solved by technology

Various wood repairing agents have been sold in the market, but these repairing agents all have disadvantages, such as commonly used NC nitro oily putty, which has a strong pungent smell during use and causes physical hazards to operators; and After the putty is dry, it is not easy to polish and color; after it dries, the organic volatiles seriously exceed the standard; for example, the furniture factory adopts the repair plan of 502 glue and sawdust, and it is difficult to sand after the 502 glue and sawdust dry, the product cannot be colored, and the repair position of the product will be in the Yellowing occurs within 3 months, affecting the appearance

preparation example Construction

[0015] The preparation method of the water-based repairing material for wood surface comprises the following steps: (1) adding quartz sand filler, film-forming aid and deionized water into the polymer emulsion, and stirring for 15-20 minutes; (2) stepping up Add antifoaming agent, defoaming agent, dispersant, thickener, preservative to the obtained product, heat, mix and stir for 60-70 minutes; (3) Detect the pH value of the obtained product in the previous step, and then add a pH regulator to adjust the pH of the product The value is slightly alkaline. Preferably, in step (1), add quartz sand filler, film-forming aid and deionized water to the polymer emulsion, and initially stir for 18 minutes. Step (2) Add foam suppressor, defoamer, dispersant, thickener, preservative to the result of the previous step, and mix and stir for 65 minutes. Step (2) The mixing temperature is not lower than 50°C, and the mixing temperature is not higher than 70°C.

Abstract

The invention discloses a waterborne repair material for a wood surface. The waterborne repair material is prepared from, by weight, 50% or more of polymer emulsion, 35-45% of quartz sand filler, 2-8%of film forming additive, less than 10% of deionized water, 0.1-0.5% of foam inhibitor and defoaming agent, 0.1-1% of dispersing agent, 0.1-1% of thickening agent, 0-0.1% of preservative and 0-0.1% of pH adjusting agent. The waterborne repair material for the wood surface has the advantages of being free of collapse, free of falling off, free of cracking, high in drying speed, easy to polish, easy to color and not prone to yellowing; odor is small, and body health of operators is protected; and according to detection of the SGS laboratory and other third-party authorities, the product contains no phthalate or harmful heavy metal or organic volatile matter, and passes the European Union REACH regulation 144 high concern material screening test.

Description

technical field [0001] The invention relates to a repairing material, in particular to a water-based repairing material for wood surfaces and a preparation method thereof. Background technique [0002] When repairing wood defects, because of various wood defects, such as cracks, insect holes, pith spots, dead knots, defects, etc., if you want to make the repair effect and repair efficiency high, you need an excellent wood repair agent. Various wood repairing agents have been sold in the market, but these repairing agents all have disadvantages, such as commonly used NC nitro oily putty, which has a strong pungent smell during use and causes physical hazards to operators; and After the putty is dry, it is not easy to polish and color; after it dries, the organic volatiles seriously exceed the standard; for example, the furniture factory adopts the repair plan of 502 glue and sawdust, and it is difficult to sand after the 502 glue and sawdust dry, the product cannot be colored...
