Abstract

The invention belongs to the technical field of paint and in particular relates to white nitrocellulose finish and a preparation method thereof. The white nitrocellulose finish is prepared from the following components: 10 percent to 35 percent of nitrocotton, 10 percent to 35 percent of alkyd resin, 8 percent to 10 percent of rosin resin, 5 percent to 15 percent of a plasticizer, 20 percent to 40 percent of titanium white, 0.1 percent to 1 percent of a dispersant, 0.5 percent to 1 percent of a de-foaming agent, 0.5 percent to 1 percent of a flatting agent, 2 percent to 4 percent of an anti-sedimentation agent, 5 percent to 10 percent of an alcohol solvent and 10 percent to 20 percent of an ester solvent. The white nitrocellulose finish provided by the invention has very good fineness and dispersion uniformity and also has very good rigidity; comprehensive properties are remarkably better than those in the prior art. The preparation method has the advantages that a process is simplified, production equipment and production procedures are reduced, the production time is shortened, the production efficiency is improved and the cost is remarkably reduced, so that the preparation method is worthy of being popularized.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a nitro white finish paint and a preparation method thereof. Background technique [0002] Nitro lacquer is a relatively common wood and decoration coating. The main film-forming material of nitro lacquer is mainly composed of nitrocellulose, combined with some soft and hard resins. Nitro topcoat is a kind of nitro paint. The advantages of nitro topcoat are environmental protection and fast drying speed, but the disadvantages are poor yellowing resistance, low plumpness and low hardness. [0003] The existing production method of nitro white topcoat requires grinding to achieve the required fineness and performance of the coating due to the use of titanium dioxide pigment in the formula. Ordinary grinding is completed by a sand machine or a three-roller machine, and the process is complicated , the production time is long, the production cost is high, the efficienc...
