Anti-blushing transparent woodwork coating and production process thereof

Abstract

The invention relates to an anti-blushing transparent woodwork coating and a production process thereof. The anti-blushing transparent woodwork coating consists of main paint, a curing agent and a thinner, wherein 2.0-4.0 weight percent of zinc stearate powder is used. Due to the use of the zinc stearate, the method not only can maintain the transparency of the paint membrane, but also can significantly improve the rubbing property of the dry membrane. However, if the zinc stearate is not used properly, serious blushing can occur in the late period. The invention solves the problem that blushing can easily occur to the double-component polyurethane transparent woodwork primer coated thickly at the low temperature and synchronously realizes the purposes of good closure, easy rubbing and long-term clear and transparent effect of the paint membrane through controlling the ratio of the zinc stearate and hydroxyl alkyd resin, the dispersion of the zinc stearate powder and the production indexes. Therefore, the invention can be widely applied in the surface protection and decoration of indoor and outdoor bamboo, wood and rattan products.

Description

technical field [0001] The invention relates to a wood coating and a production process thereof, belonging to the field of chemical coating manufacturing. Background technique [0002] At present, my country's polyurethane wood coatings account for about 80% of the total existing wood coatings. Polyurethane wood coatings have excellent mechanical and chemical properties and can be applied throughout the year. They are especially suitable for home decoration and small and medium-sized furniture factories in my country. , Wood products processing factory-based painting mode. However, due to the great difference in climate between the north and the south of my country and the four seasons, and most oil workers have not received professional training, the construction is extremely random. In order to reduce working hours and increase the amount of paint used, the interval time is continuously shortened and the amount of paint used for each course is increased. As a result, in r...

Problems solved by technology

As a result, in recent years (especially for flat construction in winter), polyurethane wood coatings frequently appear whitening in the late stage, which has caused great economic losses and negative impacts on coating companies, users and decoration families.
