Enough attractions.Publication No. CN 101481583A (Application No. 200810055733.X) Chinese invention patent application
A kind of aqueous contamination resistant heat reflection phase change insulating paint and preparation method thereof is disclosed, the composition and ratio of the coating is as follows：25~
The filming emulsion of 50 parts by weight, the heat reflection pigment of 10~25 parts by weight, the infrared external reflection filler of 2~15 parts by weight, 0~3 weight
Measure the hollow glass micropearl of part, other color stuffings of 0~5 parts by weight, appropriate auxiliary agent and appropriate deionized water.Therefore, open
Texture coating of the hair with reflective insulation function turns into important developing direction.With the continuous progress of technology, there is reflection
The texture coating of heat insulating function emerged already.Publication No. CN102229772A Chinese invention patent application discloses one kind
Heat insulating function flexible texture coating and preparation method thereof, it uses 4~8% hollow glass micropearl and 5~12% heat-insulated increasing
Strong agent enhancing heat insulating function and raising infra-red radiation effect；Publication No. CN 103031028A Chinese invention patent application is public
Open a kind of reflective insulation texture paint and preparation method thereof, using high reflection covering power polymer, polymeric hollow microsphere and
Glass bead realizes reflective insulation.To sum up, insulating moulding coating mainly uses glass microballoon or ceramic fine bead at present, and it has following lack
Point：1st, existing heat-reflecting insulating coating, temperature is reduced only by reflected sunlight, heat transfer, effect of heat insulation can not be obstructed
Unobvious, internal environment cooling unobvious.2. existing reflective heat-insulation paint does filler with ceramic fine bead, the ratio of product is great, applies
Brush finish product is low, is unfavorable for lightweight, and its effect of heat insulation is poor；3. coating thermal isolation film film thickness is thicker, effect of heat insulation is general etc. asks
