Abstract
The invention discloses a projection screen coating with a porcelain light effect. The coating comprises, by weight, 100 parts of polyvinyl chloride paste resin, 1-10 parts of ceramic powder, 10-15 parts of anatase titanium dioxide, 70-85 parts of a plasticizer and 6-14 parts of a heat stabilizer. The ceramic powder is added as a filler of the projection screen coating, and makes a projection screen have a good surface effect, porcelain light generated by the ceramic powder makes the screen have good bright gain, the cost of the screen in the invention is substantially lower than that of metal screens, and the gain effect of the projection screen is substantially better than that of glass screens.
Description
Technical field
The present invention relates to the projection screen coating of a kind of porcelain light effect.
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 projection screen coating with porcelain light effect, the composition of described coating and weight proportion thereof:
PVC paste resin 100 parts,
Ceramics 1 ~ 10 part,
Anatase thpe white powder 10 ~ 15 parts,
Plasticizer 70 ~ 85 parts,
Heat stabilizer 6 ~ 14 parts.
Preferred technical scheme is, described ceramics is the ceramic after oversintering.
It is preferred that technical scheme be that the particle diameter of described ceramics is all less than 3 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.
Advantages of the present invention and having the beneficial effects that: the present invention is by adding the porcelain powder filler as projection screen coating, it makes projection screen have good surface effect, the porcelain light of its generation makes curtain have good luminance gain, and cost is more much lower than metal curtain, and gain effect is more much better than glass curtain.
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 1
The present invention is a kind of projection screen coating with porcelain light effect, the composition of described coating and weight proportion thereof: PVC paste resin 100 parts, ceramics 1 part, anatase thpe white powder 10 parts, dioctyl adipate 85 parts, epoxy soybean oil 14 parts. Wherein, ceramics selects excellent ceramic after oversintering, and the particle diameter of ceramics is all less than 3 microns.
Embodiment 2
The present invention is a kind of projection screen coating with porcelain light effect, the composition of described coating and weight proportion thereof: PVC paste resin 100 parts, ceramics 10 parts, anatase thpe white powder 15 parts, dioctyl phthalate 70 parts, epoxy soybean oil 9 parts. Wherein, ceramics selects excellent ceramic after oversintering, and the particle diameter of ceramics is all less than 3 microns.
Embodiment 3
The present invention is a kind of projection screen coating with porcelain light effect, the composition of described coating and weight proportion thereof: PVC paste resin 100 parts, ceramics 8 parts, anatase thpe white powder 14 parts, dioctyl adipate 25 parts, dioctyl phthalate 50, epoxy soybean oil 6 parts. Wherein, ceramics selects excellent ceramic after oversintering, and the particle diameter of ceramics is all less than 3 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.
