Embodiment Construction

[0015] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] The invention relates to a slurry for manufacturing a high-brightness metal curtain. The high-brightness metal curtain is obtained through steps of S1 batching, S2 mixing, S3 film forming and S4 baking.

[0017] First of all, the S1 batching process refers to the proportioning of each raw material according to the following parts by weight:

[0018] 100 parts of polyvinyl chloride paste resin;

[0019] 3~10 parts of metal powder with glassy thin layer on the surface;

[0020] Anatase titanium dioxide 10~15 parts;

[0021] Dioctyl phthalate or / and dioctyl adipate plasticizer 70~85 parts;

[0022] 3~8 parts of chlorinated fatty acid ester surface treatment agent;

[...

Abstract

The invention discloses slurry for making a high-brightness metal screen. The invention is characterized in that the slurry is composed of, by weight, 100 parts of PVC paste resin, 3-10 parts of metal powder with a glassy thin layer on the surface, 10-15 parts of anatase titanium dioxide, 70-85 parts of dicapryl phthalate or / and dioctyl adipate plasticizer, 3-8 parts of a chlorinated fatty acid ester surface conditioning agent and 6-10 parts of an epoxidized soybean oil heat stabilizer, wherein the weight ratio of the glassy material to the metal powder without the glassy thin layer is 0.1-10%. From the perspective of formula, high-brightness gain of the metal screen is realized. As the glassy thin layer is arranged on the surface of the metal powder, the metal powder can be prevented from being oxidized during the roasting process, and the glassy thin layer on the surface can increase brightness gain of the screen. The metal screen with high-brightness gain which is obtained by the above method can be used as a 3D projection screen.

Description

technical field [0001] The invention relates to a glass bead curtain, in particular to a slurry for manufacturing a high-brightness metal curtain. Background technique [0002] At present, most projection screens used for film or video image projection are formed by superimposing a black base plate and a white polyvinyl chloride (PVC) thin layer. Traditional projection screens have low reflectivity (gain) parameters, resulting in dark projection images that need to be seen clearly in a dark space; and traditional projection screens have poor scattering capabilities, and projection images can only be seen in a dark space. Can only be seen from a small viewing angle. [0003] In order to improve the projection effect of the projection screen, people have proposed a glass bead screen with glass beads glued on the PVC film and a metal screen with a metal powder layer added on the curtain blank. The common defect of glass bead curtain is that it is afraid of moisture and easy t...
