Abstract

The invention discloses green tung oil-based paint and a preparation method thereof. The green tung oil-based paint is mainly prepared from the following raw materials in parts by weight: 40-60 partsof refined tung oil, 10-15 parts of stand linseed oil, 10-15 parts of stillingia oil, 20-35 parts of reactive tung oil diluent, 1-2 parts of compound drier, 0.2-0.4 part of antioxidant, 0.2-0.4 part of light stabilizer, 0.2-0.3 part of mildew preventive, 0.1-0.2 part of flatting agent and 0.1-0.2 part of defoaming agent. The invention further discloses the preparation method of the green tung oil-based paint. The paint has the following advantages that the tung oil is used as a main body, compounding is conducted on the tung oil, the other vegetable oil, a biological solvent, auxiliaries and the like, a safe environment-friendly nontoxic tung oil-based paint product is developed, and under a situation of guaranteeing the paint performance, the current purposes of environmental friendlinessof the paint industry can be achieved.

Description

technical field [0001] The invention belongs to the field of paint manufacturing, in particular to a green tung oil-based paint and a preparation method thereof. Background technique [0002] "Returning to nature, pursuing environmental protection" is everyone's yearning for the home living environment. At the same time, with the continuous improvement of living standards, people's desire for a healthy life is becoming more and more urgent. In recent years, various coatings have emerged in an endless stream, and manufacturers have attracted consumers' attention from various directions such as color, material and safety. At present, the existing water-based coatings on the market use water as a solvent, that is, the synthetic resin is dispersed in an aqueous solution, but its film performance and construction are easily affected by the environment, and water-based coatings are environmentally friendly, safe, and human health. There are still great hidden dangers, so it is u...
