Technical field

The invention belongs to UV technical field of coatings, and in particular to a kind of compound polyurethane material door and window UV frosted coating And preparation method.

Background technique

Building energy conservation environmental protection is always what country was advocated, and wherein door and window energy consumption accounts for 50% or so of building total energy consumption, together When high residential building it is increasing, fire prevention, fire resisting door and window demand also at increased trend year by year.Compound polyurethane material production Door and window is compared with conventional urethane door and window, and speed of production is fast, forming process is environmentally friendly, has higher intensity, modulus, thermal insulation Can, possess numerous excellent properties such as excellent air-tightness, watertightness, Wind-Pressure Resistance, sound insulation property, heat insulating ability.

Compound polyurethane material door-window section bar is made by glass fibre and polyurethane resin by pultrude process, profile production It needs to spray the coating of different colours and type after complete according to customer demand, is used in traditional mode of production based on heat curing process, it is excellent Point is heterotypic material for door-window kind, and the coating of heat cure can be in the fine of profiled piece internal curing, but the disadvantage is that thermosetting During change, production energy consumption is high, the production time is long, occupation area of equipment is big, while solvent volatilization will cause great VOC row It puts, pollutes environment, and spray loss greatly, recycling is difficult.

Low energy consumption for UV curing process, non-volatility solvent in production process, does not generate VOC emission, is a kind of environmentally friendly, section Energy, efficient production technology.But existing UV is coating material solidified, is difficult to apply on compound polyurethane material door and window, reason is Door-window section bar is mostly abnormally-structured, is different from heat curing process, the weaker part of abnormally-structured middle illumination is difficult to solidify, even if more The secondary still difficult ideal effect of acquisition after repeating illumination, is not achieved the requirement of coatings of door and window.

Summary of the invention

The purpose of the present invention is to provide a kind of compound polyurethane material door and window UV frosted coating and preparation methods, with solution Certainly the problems mentioned above in the background art.

To achieve the above object, the invention provides the following technical scheme: a kind of compound polyurethane material door and window UV frosted Coating and preparation method, the raw material including following parts by weight:

Preferably, the preparation method comprises the following steps:

1) pigment and sand flour are added according to the ratio in matrix resin, dispersion, revolving speed is stirred in high speed disperser 1000-1500 revs/min, disperse 1-2 hours；

2) reactive diluent monomer, photoinitiator, adhesion promoter, levelling agent, defoaming agent are added according to the ratio, continues to stir Dispersion is mixed, 3500-5000 revs/min of revolving speed, disperses 1 hour, UV frosted coating is made.

Preferably, the adhesion promoter is phosphate CD-9051 type promotor.

Preferably, the levelling agent is byk-333 type levelling agent.

Preferably, the defoaming agent is B-461 type defoaming agent.

Preferably, the sand flour be polyacrylic polymer, 50 microns of granular size.

Preferably, the pigment is brown color organic pigment.

Technical effect and advantage of the invention: compound polyurethane material door and window UV frosted coating and the preparation method, UV Low energy consumption for curing process, non-volatility solvent in production process, does not generate VOC emission, is a kind of environmentally friendly, energy saving, efficient life Production. art is able to satisfy the solidification of abnormally-structured door and window.

Specific embodiment

Below in conjunction in the embodiment of the present invention, technical solution in the embodiment of the present invention is clearly and completely retouched It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.
