Embodiment 1

[0026] Prepare Part A:

[0027] Select a clean and standard dispersing cylinder, and the production process: Add 45 kg of short oil alkyd resin, 1.2 kg of dispersant (EFKA-4010), 3 kg of methyl isobutyl ketone (MIBK) in sequence, at a low speed of 600~800 r / After adding 5 kg of quartz powder (VX-SP) at a speed of 1 min, disperse at a medium speed of 800~1200 r / min for 15~20 min until the fineness is ≤ 25 μm, and then add 20 kg of castor oil alkyd resin in sequence , 5 kg of 15wt% polyamide wax, 6 kg of propylene glycol methyl ether acetate, put into the dispersion tank, disperse at a medium speed of 800~1200r / min for 10 minutes until fully uniform, then add 1 kg of 1778 wax powder, matting powder (Grace ED-2) 7 kg, clean the side of the tank with 2 kg of butyl acetate, disperse at high speed for 10~15 minutes, until the fineness is ≤25 μm, add 1 kg of leveling agent EFKA-3777, 0.3 kg of leveling agent BYK-333, 0.5 kg of Foaming agent BYK-141, using 3 kg of propylene glycol m...

Embodiment 2

[0033] Prepare raw materials according to Table 1; adopt the same method as in Example 1 to prepare component A, component B and component C in sequence;

[0034] Adopt the same using method as embodiment 1;

[0035] Table 1:

[0036]

Embodiment 3

Abstract

The invention relates to wear-resistant anti-cracking PU matt floor paint, belonging to the wooden floor paint manufacturing industry. In the wear-resistant anti-cracking PU matt floor paint provided by the invention, the short-oil alkyd resin, castor oil alkyd resin, TDI addition product curing agent, TDI trimer curing agent and HDI trimer curing agent are used as the main paint film forming matters, and the crosslinking degree is remarkably improved; under the effect of a dispersant EFKA-4010, the film forming matters interact with quartz powder; after film formation, the floor paint can be uniformly and neatly arranged on the surface of the pain film so that the paint film has relatively high hardness. The HDI hexamethylene diisocyanate in the trimer curing agent (HX-90B) interacts with the components such as short-oil alkyd resin and castor oil alkyd resin, and the flexibility of the paint film is remarkably improved. Therefore, by adopting the wear-resistant anti-cracking PU matt floor paint provided by the invention, the hardness of the paint film is improved while the flexibility of the paint film can be remarkably improved so as to overcome the contradictory relation between hardness and flexibility.

Description

technical field [0001] The invention relates to a wear-resistant and anti-crack PU matte floor paint, which belongs to the wooden floor paint manufacturing industry. Background technique [0002] Ordinary PU matte varnish is a coating with excellent comprehensive properties widely used in the field of wood, which can satisfy the coating of ordinary wood, but the wooden floor needs a coating with higher hardness, better wear resistance and flexibility , Ordinary PU matte clear topcoat is far from meeting the above requirements. Floor paint, used for floor coatings for building interior floor coating finishes; its performance indicators include wear resistance, impact resistance, hardness, adhesion, dust resistance Performance, cleaning performance, anti-static performance, etc. Among them, hardness performance (wear resistance, scratch resistance) and flexibility (crack resistance, smoothness) are the two most important aspects; and there is a contradictory relationship bet...
