Abstract
The invention discloses high-definition high-brightness projection screen coating. The coating is composed of, by weight, 100 parts of PVC paste resin, 0.5-3 parts of transparent methacrylic resin microspheres, 0.5-3 parts of glass powder, 1-3 parts of metal powder, 10-15 parts of anatase titanium dioxide, 65-85 parts of a plasticizer, 2-10 parts of a heat stabilizer, 0-1 part of a wetting agent and 0-1 part of a dispersant. By adding the transparent methacrylic resin microspheres, glass powder and metal powder which are used as a filler of the projection screen coating, the methacrylic resin microspheres have good adhesiveness with PVC and are lightweight. Thus, the methacrylic resin microspheres are not easy to fall off. The metal powder can further improve beneficial effects of a projection screen. The glass powder increases brightness of the projection screen. Through particle size matching of the above three ingredients, the projection screen can have high definition and high brightness in a wider perspective. In addition, cost of the projection screen is much lower than cost of a traditional metal screen. The high-definition high-brightness projection screen coating is a projection screen making material suitable for family use.
Description
Technical field
The present invention relates to a kind of highlighted projection screen coating of high definition。
Background technology
Mostly the projection screen being presently used for film or video image projection is by polrvinyl chloride (PVC) thin layers of a black floor and a white。Traditional projection screen reflectance (gain) parameter is low, causes the color of image that projection presents dark, it is necessary to just can see the image of projection in dark space clearly；And traditional projection screen scattering power is poor, the image that projection presents just can only be seen clearly in small angle。
In order to improve the drop shadow effect of projection screen, there has been proposed a kind of gluing in PVC film and sticked the glass micro-bead curtain of glass microballoon and on curtain base, added the metal curtain of metal bisque。Glass micro-bead curtain is common has the drawback that fearness tide, easily falls pearl。And by contrast, metal curtain is after-applied on curtain base due to metal powder and mixed with resin, so there is no dry linting or be afraid of the defect of tide, and luminance gain is high, but metal curtain is relatively costly。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of not easily dry linting and there is the projection screen coating of favorable luminance gain。
For achieving the above object, the technical scheme is that a kind of highlighted projection screen coating of high definition, the composition of described coating and weight proportion thereof:
PVC paste resin 100 parts,
Transparent methacrylic resin microsphere 0.5 ~ 3 part,
1～3 part of glass dust,
Metal powder 0.5～3 part,
Anatase thpe white powder 8 ~ 15 parts,
Plasticizer 65 ~ 85 parts,
Heat stabilizer 2 ~ 10 parts,
Wetting agent 0～1 part,
Dispersant 0～1 part。
It is preferred that technical scheme be that the particle diameter of described transparent methacrylic resin microsphere is 0.5 ~ 1 micron, and the particle diameter of described glass dust is 1～3 micron, and the particle diameter of described metal powder is 3 ~ 6 microns。
Preferred technical scheme is, described plasticizer is one or both in dioctyl phthalate, dioctyl adipate。
Preferred technical scheme is, described heat stabilizer is epoxy soybean oil。
Preferred technical scheme is, described dispersant is BKY-9076, and described wetting agent is polyvinylpyrrolidone。
Advantages of the present invention and having the beneficial effects that: the present invention is by adding transparent methacrylic resin microsphere, glass dust and the metal powder filler collectively as projection screen coating, and methacrylic resin microsphere is good with PVC cohesive, and light weight, therefore difficult drop-off；Metal powder can improve the gain effect of projection screen further；Glass dust increases the brightness of projection screen；And three is arranged in pairs or groups by particle diameter so that projection screen can present fine definition and high brightness at broader visual angle, and cost is also much lower than conventional metals curtain, it is that the projection screen that a kind of applicable family uses manufactures material。
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described。Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this。
