Problems solved by technology

[0002] Most of the current nitro paints use high-second nitrocellulose, and there is no strict control over the volatile components. If they are made into low-solid and high-viscosity paints, more thinners are added during use, so the volatile organic The amount of compound (VOC) is relatively large

Abstract

The invention relates to a nitrocellulose lacquer and a preparation method thereof, in particular to an environment-friendly nitrocellulose lacquer for wood-ware, which is used for protecting the surface finish of a wood-ware product, and a preparation method of the environment-friendly nitrocellulose lacquer for wood-ware. The environment-friendly nitrocellulose lacquer for wood-ware comprises the ingredients by part by weight: 10 to 15 parts of ethyl acetate, 3 to 8 parts of butanol, 10 to 20 parts of nitrification cotton, 1 to 3 parts of environment-friendly plasticizer, 20 to 25 parts of non-benzene alkyd resin, and 2 to 5 parts of polishing powder. The raw materials are screened and controlled, low second nitrification cotton and lipid resolvent which has low compact on the environment and human bodies are selected as raw materials, the solid content of the lacquer is improved, and the heavy metal contents of all the raw materials meet the control requirements of international standards, so that the impact on the environment of the product is reduced. As the lacquer has a high solid content and a low viscosity, the construction times can be reduced, and the adding quantity of diluent is also reduced. Therefore, the emission of VOC and the environmental pollution are reduced.

Description

technical field [0001] The invention relates to a nitro-based paint and a manufacturing method thereof, in particular to an environment-friendly nitro-based wood varnish used for surface decoration and protection of wooden products and a manufacturing method thereof. Background technique [0002] Most of the current nitro paints use high-second nitrocellulose, and there is no strict control over the volatile components. If they are made into low-solid and high-viscosity paints, more thinners are added during use, so the volatile organic The amount of compound (VOC) is relatively large. Contents of the invention [0003] In view of this, the technical problem to be solved in the present invention is to provide a kind of environment-friendly nitro wood lacquer, this environment-friendly nitro wood lacquer is by re-selecting and controlling the raw materials, selecting low-second nitrocellulose and environmental protection, Lipid solvents that have less impact on the human ...
