Problems solved by technology

[0004] Chinese invention patent CN201210283927.1 provides a hand-swept PU transparent primer for furniture factories. It is made of three components such as main paint, curing agent and thinner. It has the characteristics of high cost performance and meets the requirements of environmental protection and health. At the same time, the hand-sweeping property is good, the thick coating is not easy to foam, the adhesion is strong, and the sanding property is good. However, the PU transparent primer contains a lot of heavy solvents and thinners, which affects the quick-drying effect of the primer.
Chinese invention patent CN201310442820.1 provides a quick-drying PU transparent primer formula, the main raw materials include castor oil alkyd resin, xylene, zinc stearate, etc., with good transparency, strong filling, easy to polish and not easy Bubbling and other effects, however, the PU transparent primer contains xylene, the environmental protection performance does not meet the requirements, and the quick-drying effect is not ideal
In addition, due to the uneven skills of construction personnel in the market and the different construction environments, ordinary primers are prone to problems such as prickly heat and pinholes in the paint film after construction, which seriously affects the coating effect and cannot meet the coating requirements of high-end furniture.

Abstract

The invention provides transparent primer easy to apply. The transparent primer is prepared from main paint, a curing agent and a diluting agent, wherein a ratio of the three components is 1 to (0.3 to 0.5) to (0.5 to 0.7), the main paint is prepared from alkyd resin, acrylic modified alkyd resin, an anti-settling agent, a defoaming agent, a composite drying agent, zinc stearate, talcum powder and a composite solvent, the curing agent is prepared from a TDI addition product curing agent, a TDI trimer and butyl acetate, and the diluting agent is prepared from dimethylbenzene, butyl acetate and propylene glycol methyl ether acetate. The primer easy to apply has the characteristics of convenience in construction, high surface compactness and smoothness, good toughness, excellent grinding performance and prinkly heat prevention and also meets the environment-friendly and energy-saving requirements at the same time.

Description

technical field [0001] The invention belongs to the technical field of primers for furniture, and in particular relates to an easy-to-paint transparent primer and a preparation method thereof. Background technique [0002] Wood paints are mainly divided into two categories: water-based paints and oil-based paints. Oil-based paints are divided into four categories: PU, PE, NC and UV. PU paint refers to a paint that contains a considerable amount of urethane bonds in its paint film, also known as polyurethane paint. PU paint forms a film through the chemical reaction between the main paint, curing agent and thinner. It is characterized by a complete range of primers to top coats. It is currently the most widely used and mature product in the field of furniture paint. In terms of performance, under the same hardness, due to the effect of hydrogen bonds, the PU paint film has the highest elongation at break, so it is widely used in floor paint and deck paint. The coating of pi...
