Embodiment Construction

[0032] 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.

[0033] The invention relates to a method for preparing a high-brightness gain metal curtain, which is obtained through steps of S1 batching, S2 mixing, S3 film making and S4 baking.

[0034] First of all, the S1 batching process refers to the proportioning of each raw material according to the following parts by weight:

[0035] 100 parts of polyvinyl chloride paste resin,

[0036] Metal powder 3~10 parts,

[0037] Anatase titanium dioxide 10~15 parts,

[0038] Dioctyl phthalate or / and dioctyl adipate plasticizer 70~85 parts,

[0039] 3~8 parts of chlorinated fatty acid ester surface treatment agent,

[0040] Epoxy soybean oil heat stabilizer 6~10 parts.

[0041] Secondly...

Abstract

The invention discloses a high luminance gain metal curtain preparation method. The high luminance gain metal curtain preparation method comprises dosing, mixing, film manufacturing and baking processes sequentially. According to the dosing process, raw materials comprise, by weight, 100 parts of polyvinyl chloride (PVC) pastes, 3-10 parts of metal powder, 10-15 parts of anatase titanium dioxide, 70-85 parts of dioctyl phthalate or / and dioctyl adipate plasticizers, 3-8 parts of chlorination aliphatic ester surface treating agents, and 6-10 parts of epoxidized soybean oil heat stabilizers. The mixing process comprises the following steps: premixing all the raw materials in the dosing process S1, grinding sizing agents through a three-roll grinder, standing and dissolving, and dispersing through a dispersion machine. According to the film manufacturing process, a scraper coating machine coats the sizing agents obtained through the mixing process on a curtain blank in a scraping mode. According to the baking process, a subsection baking process with temperature increased successively is adopted for baking the curtain blank coated with the sizing agents in the scraping mode. Compared with the prior art, luminance gain of a metal curtain obtained through the method is high and can reach 3.0-3.5.

Description

technical field [0001] The invention relates to a glass bead curtain, in particular to a method for preparing a high-brightness gain 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 ...
