Abstract
The invention relates to a construction method for preventing a polyurethane clear lacquer film from blushing. The method comprises the following steps: step (1), conducting sanding on materials; step (2), conducting coloring on the materials; step (3), brushing or spraying anti-blushing sealing priming lacquer; step (4), brushing or spraying polyurethane clear priming lacquer, and then repeating step (4) for two times; and step (5), brushing or spraying polyurethane clear finishing lacquer, and obtaining the polyurethane clear lacquer film after drying for 24 to 36 hours. Compared with the prior art, the invention has the benefits that the method can effectively prevent the polyurethane clear lacquer film from blushing; after the polyurethane clear lacquer film is placed in the atmospheric environment or in the constant temperature and humidity test chamber for one month after construction, no blushing phenomenon occurs; and the polyurethane clear lacquer film obtained after construction is fresh and natural, has the effect of imitation of natural marble, is tangible in winter and bulky in hand, feels gentle and can meet the demands of decoration.
Description
Technical field
The present invention relates to a kind of construction method of polyurethane transparent lacquer, be specifically related to a kind of construction method that prevents that polyurethane transparent lacquer paint film from turning white.
Background technology
Polyurethane coating has good adhesive force, fabulous decorate properties, more comprehensively chemical resistance and workability easily because of it, and is widely used in furniture decoration and the interior decoration.Yet, owing in the bigger environment of air humidity, construct, perhaps because improper to the preliminary treatment of base material, cause polyurethane coating in when construction or construction back several days, tens days, some months and even longer time, behind the drying varniss, the moisture that airborne moisture penetrates between paint film or in the base material easily penetrates between paint film, the phenomenon that paint film turns white appears, cause material outward appearance after the application not attractive in appearance, do not reach required decorative effect, serious bring great economic loss and prestige injury.Therefore need a kind of suitable construction method, blushing occurs with the polyurethane transparent lacquer paint film after preventing to construct.
Summary of the invention
The purpose of this invention is to provide a kind of construction method that prevents that polyurethane transparent lacquer paint film from turning white, occur the defective of turning white easily to overcome polyurethane transparent lacquer paint film that existing construction method obtains.
A kind of construction method that prevents that polyurethane transparent lacquer paint film from turning white comprises the steps:
(1) material sanding:, make it smooth smooth with sand paper sand milling material;
(2) material is painted: fill out agent Jia Gelisi with painted high adhesion force, evenly wiping is one time, dry 1～2 hour;
(3) the anti-seal coat that turns white is brushed or spraying: transferred to 8～10 seconds with the anti-seal coat diluent that turns white will prevent the turning white viscosity of seal coat, evenly spray " a ten " word or brush dry 4～6 hours one time;
(4) polyurethane transparent priming paint is brushed or spraying: with polyurethane transparent priming paint diluent polyurethane transparent priming paint viscosity was transferred to 16～18 seconds, evenly spray two " ten " words or brush " a ten " word, dry 6～8 hours, and then this step of repetitive operation (4) twice;
(5) the polyurethane transparent finish paint is brushed or spraying: with polyurethane transparent finish paint diluent polyurethane transparent finish paint viscosity was transferred to 14～16 seconds, evenly spray two " ten " words or brush two " ten " words, after dry 24～36 hours, obtain product.
Further, after each step of operation (2) to (4), and between each operation of (4), all material is carried out sanding and handle, smooth, smooth with the sand paper sand milling.
Further, described material is that medium-density plate pastes wooden skin or the made ornament materials of all kinds of solid wood.
Described " ten " word is meant coated article is vertically from first to last sprayed one time comprehensively, laterally from first to last sprays one time then comprehensively, presents " ten " word cross-like twice.
Described viscosity is meant the viscosity of being surveyed with rock field 2# cup.
Anti-turn white seal coat, polyurethane transparent priming paint, polyurethane transparent finish paint, fill out agent and Ge Lisi, and the diluent that is adopted, all can adopt the commercially available prod, as adopting the conventional products of Shanghai Fu Chen company.
Compared with prior art, the invention has the beneficial effects as follows: can prevent effectively that polyurethane transparent lacquer paint film from turning white, after construction, be placed on respectively in atmospheric environment and the constant temperature humidity chamber 1 month does not all have the phenomenon of turning white appearance; And the product that the construction back obtains has fresh and clean, imitating effect of natural marbles, and touch winter, good hand feeling, and sensation is gentle, and can satisfy the demand of decoration.
