Abstract
The invention discloses a durable 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, 10-15 parts of anatase titanium dioxide, 70-85 parts of a plasticizer, 2-10 parts of a heat stabilizer and 0-2 parts of other auxiliaries. By adding the transparent methacrylic resin microspheres 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. In addition, the transparent methacrylic resin microspheres also have a good light reflecting effect so as to improve beneficial effects of a projection screen. Cost of the projection screen is much lower than cost of a metal screen or a glass screen. The durable projection screen coating is a projection screen making material suitable for family use.
Description
Technical field
The present invention relates to a kind of durable 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 durable 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,
Anatase thpe white powder 10 ~ 15 parts,
Plasticizer 70 ~ 85 parts,
Heat stabilizer 2 ~ 10 parts,
Other auxiliary agents 0～2 part。
It is preferred that technical scheme be that the particle diameter of described transparent methacrylic resin microsphere is all less than 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, other auxiliary agents described include at least one in dispersant, wetting agent。
Advantages of the present invention and having the beneficial effects that: the present invention is by adding the transparent methacrylic resin microsphere filler as projection screen coating, and methacrylic resin microsphere is good with PVC cohesive, and light weight, therefore difficult drop-off；Otherwise see-through methacrylic resin microsphere also has good luminous reflectance effect, it is possible to improve the gain effect of projection screen, and cost is also much lower than metal curtain and glass curtain, 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。

Embodiment 2
The present invention is a kind of durable projection screen coating, the composition of described coating and weight proportion thereof: PVC paste resin 100 parts, transparent methacrylic resin microsphere 3 parts, anatase thpe white powder 10 parts, dioctyl phthalate 70 parts, epoxy soybean oil 10 parts。Wherein, the particle diameter of transparent methacrylic resin microsphere is all less than 5 microns。
Embodiment 3
The present invention is a kind of durable projection screen coating, the composition of described coating and weight proportion thereof: PVC paste resin 100 parts, transparent methacrylic resin microsphere 2 parts, anatase thpe white powder 15 parts, dioctyl adipate 34 parts, dioctyl phthalate 38, epoxy soybean oil 6 parts, polyvinylpyrrolidone 0.5 part, BYK-90760.5 part。Wherein, the particle diameter of transparent methacrylic resin microsphere is all less than 5 microns。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention。
