A kind of woodenware high-performance crack resistence unsaturated polyester based white primer
Technical field
The invention belongs to paint field, be specifically related to a kind of woodenware high-performance crack resistence unsaturated polyester based white primer.
Background technology
All the time, on furniture market, unsaturated polyester based white primer with its large arch dam and excellence fillibility in occupation of many market shares, due to construction wrong, disposable thick painting in woodwork coating process, or employ non-supporting solvent or diluent, amass the place that oil is thicker at some groove place or carving place, easily there is the risk of the cracking of certain probability, even if the product that resin content is relatively high is also difficult to escape by luck, causes and do over again, affect production efficiency.And very easily produce relevant dispute in Furniture Factory to Paint Factory.Trace it to its cause, being mainly unsaturated polyester varnish is cross-linking reaction type coating, and cross-linking density is large, and fragility is strong, and the stress that thick painting itself produces accumulation is comparatively large, and in addition, due to market competition, solvent or diluent does not often use auxiliary products, increases the risk of cracking.Research and develop a construction tolerance good, high-performance resists the unsaturated polyester based white primer of thick painting cracking imperative.
Summary of the invention
The object of the invention is to provide a kind of woodenware high-performance crack resistence unsaturated polyester based white primer, solves unsaturated polyester based white primer common on the market and constructs in carving or groove place due to construction wrong once thick painting or use non-supporting solvent or diluent easily to produce the problem of the risk of cracking.

The present invention compared with prior art tool has the following advantages:
The present invention considers the reason of market orientation and cost performance, adopt new type of toughening agent and the toughness reinforcing composite coordination plasticizing of response type, sag prevention additive compound reduces long-pending core intersection, and passes through the color stuffing of collocation different sorts, different-grain diameter, different hardness, increases compactness and the force of cohesion of film.By a large amount of experiments, determine optimum proportion.Obtained unsaturated polyester based white primer construction tolerance is high, and thick painting cracking resistance effect is fine.
Unsaturated polyester based white primer of the present invention, compared with unsaturated polyester based white primer common on market plane, solves the thick risk being applied to groove or carving cracking, good to the non-supporting solvent or diluent tolerance on market.
