Abstract

The invention provides water-based wood lacquer and a preparation method thereof. The water-based wood lacquer is prepared from the following components in parts by weight: 40 to 50 parts of sucrose polyester and acrylic acid combined modified alkyd resin, 20 to 30 parts of aliphatic modified polyurethane dispersoid, 12 to 18 parts of chlorine vinegar resin, 2 to 3 parts of an emulsifier, 2 to 3 parts of a dispersant, 1 to 2 parts of a defoaming agent, 1 to 2 parts of a flatting agent, 2 to 3 parts of an accelerant, 1 to 2 parts of an initiator and 20 to 30 parts of deionized water. The wood lacquer provided by the invention is short in surface drying and hard drying time and can be dried quickly; a coating film formed by the wood lacquer has high hardness, high wear resistance and excellent water resistance; furthermore, the wood lacquer has low VOC level and higher environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of wood lacquer, in particular to a water-based wood varnish and a preparation method thereof. Background technique [0002] Wood paint can be seen everywhere in daily life. It not only has decorative and beautifying effects, but also plays a good role in protecting wood. It can be divided into two categories: water-based and oil-based. Among them, water-based wood paint uses water as a solvent without any harmful gas volatilization. It is currently the safest and most environmentally friendly furniture paint. my country's research on water-based wood lacquers has been developed for quite a long time. With the development of water-based resins, additives, fillers and other technologies, in recent years, water-based wood lacquers have gained scale in the fields of children's furniture with strict environmental protection requirements. application. [0003] However, the disadvantages of water-based wood lacqu...
