Embodiment 1

[0049] Weigh 18.9kg of deionized water and 65kg of resin, and put in 0.2kg of wetting agent, 0.4kg of defoamer, and 0.3kg of dispersant in sequence at a speed of 300-600 rpm; at a speed of 600-1000 rpm, Sequentially put in nano-SiO 2 0.5kg, glass powder slurry 10kg, matting powder 1.5kg, and then disperse at a high speed for 10-60 minutes at a speed of 1200-1500 rpm; the fineness of the quality inspection is ≤20μm; Membrane aid 3kg, rheological agent 0.2kg, disperse at high speed for 10-30 minutes until there is no shrinkage cavity, and get the main paint component 1 after filtration. Weigh 20.0kg of PMP and 80.0kg of curing agent, mix and stir evenly to obtain component 2. During construction, only need to press component 1: component 2 is 1:0.375 weight ratio, and then manually stir for 5-10 minutes. It can be applied after uniformity.

Embodiment 2

[0051] Weigh 8.5kg of deionized water and 70kg of resin, and put in 0.25kg of wetting agent, 0.35kg of defoamer, and 0.35kg of dispersant in sequence at a speed of 300-600 rpm; at a speed of 600-1000 rpm, Sequentially put in nano-SiO 20.6kg, glass powder 15kg, matting powder 1.2kg, and then disperse at high speed for 10-60 minutes at 1200-1500 rpm; quality inspection fineness ≤ 20μm; at 100-400 rpm, put into film formation in turn Auxiliary agent 3.5kg Rheological agent 0.25kg High-speed dispersion for 10-30 minutes until there is no shrinkage cavity After filtration, the main paint component 1 is obtained. Weigh 25.0kg of PMP and 75.0kg of curing agent, mix and stir evenly to obtain component 2. During construction, it is only necessary to press the weight ratio of component 1: component 2 to be 1:0.43, and then manually stir for 5-10 minutes, and the construction can be carried out after uniformity.

Embodiment 3

[0053] Weigh 1.1kg of deionized water and 75kg of resin, and put in 0.3kg of wetting agent, 0.4kg of defoamer, 17kg of glass powder, and 0.3kg of dispersant at 600-1000 rpm at a speed of 300-600 rpm At the rotating speed, input nano-SiO 2 0.6kg, 1.0kg of matting powder, and then disperse at high speed for 10-60 minutes at 1200-1500 rpm; quality inspection fineness ≤ 20μm; Rheological agent 0.3kg, disperse at high speed for 10-30 minutes until there is no shrinkage cavity, and get the main paint component 1 after filtering. Weigh 30.0kg of PMP and 70.0kg of curing agent, mix and stir evenly to obtain component 2. During construction, you only need to use the weight ratio of component 1:component 2 to be 1:0.5, and then manually stir for 5-10 minutes , can be constructed after uniformity.

[0054] In the above-mentioned embodiment, the effect after construction and use is shown in the following table 1, and the technical requirements are conventional main technical index requ...

Abstract

The invention discloses a high hardness abrasive resistance bi-component waterborne wood lacquer and a preparation method thereof. The bi-component waterborne wood lacqure comprises two components; wherein, component one is a hydroxyl component and comprises according to the parts by weight: 1-20 parts of deionized water, 60-80 parts of resin, 0.1-0.3 part of wetting agent, 0.3-1.0 part of dispersant, 0.03-0.3 part of foam killer, 0.5-1.0 part of nanometer SiO2, 10-20 parts of glass powder pulp, 0-3.0 parts of flatting agent, 1.0-3.0 parts of film forming addition agent, 0.3-1 part of wax addition agent, and 0.01-1.0 part of rheological agent; component two is an isocyanate component and comprises according to the parts by weight: 10-30 parts of PMP and 60-90 parts of firming agent. The invention has the following advantages that a pain film has higher pain film hardness and abrasive resistance, more prominent thermal stability, better contamination resistance and chemical resistance, long usage period, and is easy to be constructed.

Description

technical field [0001] The invention relates to a wood coating, more specifically, to a high-hardness wear-resistant two-component water-based wood coating and a preparation method thereof. Background technique [0002] Most of the wood coatings used in my country's existing home decoration and furniture production are solvent-based polyurethane and nitro-based coatings. Their VOC content is high, and a large amount of harmful gases are produced after coating, which seriously pollutes the environment and causes human lung disease. The culprits of edema, central nervous system depression, respiratory and circulatory failure, liver poisoning and other diseases, completely eliminating the hidden dangers of home decoration to human health, and creating a harmonious, clean, healthy, environmentally friendly and safe ecological environment has become an urgent problem to be solved all over the world . It has become an inevitable development trend for water-based wood coatings to re...
