[0056] Described zinc stearate adopts Lihe 1819 zinc stearate;

[0057] The hydroquinone solution is prepared by dissolving analytically pure hydroquinone in 1% ethyl acetate.

[0058] The preparation method of t...

Embodiment 2

[0068] The difference between this example and Example 1 is that the main ingredient A includes the following components in mass percentage:

[0069] Unsaturated polyester resin 86%;

[0070] Defoamer 0.2%;

[0071] Leveling agent 0.2%;

[0072] Dispersant 0.3%;

Abstract

The invention discloses a solvent-free odor-free unsaturated polyester wood coating material and a preparation method thereof, and belongs to the field of coating materials. The solvent-free odor-free unsaturated polyester wood coating material is prepared from a main agent A, a main agent B, a curing agent and a drier, wherein the main agent A is prepared from 75 to 95 percent of unsaturated polyester resin, 0.2 to 0.3 percent of a defoaming agent, 0.2 percent of a flatting agent, 0.3 to 0.5 percent of a dispersing agent, 0 to 20 percent of talcum powder,2.2 to 3 percent of zinc stearate, 0.7 percent of silicon dioxide and 0.2 to 0.5 percent of a hydroquinone solution. The preparation method of the main agent A comprises the following steps: firstly putting the unsaturated polyester resin into a stirring machine, and sequentially an assistant and hydroquinone under a stirring state of which the rotating speed is 500 r / min; putting the talcum powder, the zinc stearate and the silicon dioxide under the stirring state five minutes later, and stirring at a high speed; filtering after stirring, thus obtaining the main agent A. The solvent-free odor-free unsaturated polyester wood coating material provided by the invention is solvent-free and has no an irritant smell; the solid content is high, and the drying time during application of the solvent-free odor-free unsaturated polyester wood coating material can be favorably shortened.

Description

technical field [0001] The invention relates to the field of paint and its preparation technology, in particular to a solvent-free, odor-free unsaturated polyester wood paint and a preparation method thereof. Background technique [0002] Coating is a widely used polymer product. It is used in various departments of daily life, national economy and national defense construction. In recent years, the coating industry has developed rapidly, from general-purpose coatings with decorative and protective functions to those that can change the coated objects. Special coatings with various properties on the surface. As we all know, traditional solvent-based coatings emit a large amount of volatile organic compounds into the air during the process of manufacturing, construction, drying, curing, and film formation. The odor is unpleasant and poses a serious pollution and threat to the human ecological environment. For this reason, as people's awareness of protecting the environment a...
