Thixotropic soybean oil paint and preparation method thereof

Abstract

The invention provides a thixotropic soybean oil paint, which is prepared by mixing the following raw materials in percentage by weight: 55%-65% of modified soybean oil resin, 0.2%-0.8% of defoaming agent, 0.1%-0.3% of anti-skinning agent, 2.0%-3.5% of fumed silica, 1.0%-1.5% of bentonite, 0.4%-0.9% of drier, 0%-1.8% of flatting agent, 20%-35% of nonbenzenoid organic solvent and 0%-15% of raw pigment materials. The thixotropic plant oil paint has the advantages of good permeability, favorable adhesive force, quick drying, high solid content, high sag resistance of a vertical surface, low smell and no toxicity. The thixotropic soybean oil paint can be used for both fully-enclosed coating and open coating, and the product conforms to national standards and laws and regulations for exportingto USA and European Union.

Description

technical field [0001] The invention relates to a coating, in particular to a thixotropic soybean oil coating and a preparation method thereof. Background technique [0002] With the development of the economy, people are exposed to more and more chemical substances, and many people want to return to nature. There is such a trend in the current high-grade wooden windows or furniture coatings. More and more people hope to get Coating products are made using natural vegetable oils. At present, many manufacturers use tung oil or wood wax oil to prepare coating products, but the drying speed is slow, the weather resistance is not strong, the appearance viscosity is high, and it can only be rubbed, not suitable for spraying; even if the tung oil and wood wax oil are diluted with a solvent To adapt to spraying, but there will be sagging in the process of spraying non-planar plates, which cannot adapt to industrial production. At the same time, there is not much room for product g...
