Abstract
The invention discloses a highlight projection screen coating. The coating comprises, by weight, 100 parts of polyvinyl chloride paste resin, 0.5-3 parts of transparent methacrylic resin microspheres, 1-3 parts of glass powder, 10-15 parts of anatase titanium dioxide, 70-85 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. The transparent methacrylic resin microspheres and the glass powder are simultaneously used as the filler of the projection screen coating, and the methacrylic resin microspheres have good adhesion to PVC, so the screen coating has light weight and difficultly sheds; the glass powder can further improve the gain effect of the projection screen; and particle size matching of the glass powder and the transparent methacrylic resin microspheres makes the projection screen integrally have high light and the cost of the projection curtain be lower than that of metal screens and traditional glass screens, so the coating is a projection screen manufacturing material suitable for being used in households.
Description
Technical field
The present invention relates to a kind of highlighted projection screen coating.
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, 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,
Anatase thpe white powder 8 ~ 15 parts,
Plasticizer 70 ~ 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 2 ~ 5 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 and the glass dust filler collectively as projection screen coating, and methacrylic resin microsphere is good with PVC cohesive, and light weight, therefore difficult drop-off; Glass dust can improve the gain effect of projection screen further; And glass dust and transparent methacrylic resin microsphere arranged in pairs or groups by particle diameter so that projection screen entirety presents high brightness, and cost is also much lower than metal curtain and traditional glass 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.
