Embodiment 1

[0024] A projector screen provided in this embodiment is made by curing the base layer 1, the adhesive layer 2, and the reflective layer 3 by hot pressing and then coating a silicone protective layer 4, such as figure 1 shown.

[0025] The above-mentioned basic bottom layer is a multi-axial woven fabric layer soaked with the first immersion liquid; the first immersion liquid is a resin composition, and the above-mentioned resin composition includes 100 parts of polyurethane resin, 0.5 parts of catalyst, 25 parts of soaking agent, 0.6 parts of coupling agent, 0.6 parts of UV absorber, 5 parts of flame retardant, 18 parts of defoaming agent and 25 parts of silicone fabric finishing agent, and 32 parts of curing agent. The second immersion solution is a chitosan solution with a concentration of 1%.

Embodiment 2

[0027] The resin composition of the first immersion solution provided in this embodiment comprises, by weight, 100 parts of polyurethane resin, 0.6 part of catalyst, 15 parts of sizing agent, 0.5 part of coupling agent, 1 part of ultraviolet absorber, 8 parts of flame retardant agent, 25 parts of defoamer and 20 parts of silicone fabric finishing agent, and 35 parts of curing agent. The second immersion solution is a chitosan solution with a concentration of 0.8%.

Embodiment 3

[0029] The resin composition of the first immersion solution provided in this embodiment includes, by weight, 100 parts of polyurethane resin, 0.4 part of catalyst, 23 parts of sizing agent, 0.4 part of coupling agent, 0.8 part of ultraviolet absorber, 6 parts of flame retardant agent, 20 parts of defoamer and 22 parts of silicone fabric finishing agent, and 30 parts of curing agent. The second immersion liquid is a chitosan solution with a concentration of 1.5%.

Abstract

The invention provides a projector curtain and a preparation method thereof. The projector curtain is prepared through thermocompression of a basic bottom layer, an adhesion layer and a light reflecting layer and coating of an organosilicon protecting layer, wherein the basic bottom layer is multiaxial woven fabric layer soaked in a first soaking solution; the first soaking solution is resin composition, and the resin composition is prepared from, in parts by weight, 100 parts of polyurethane resin, 0.2-0.8 parts of a catalyst, 15-25 parts of an impregnating compound, 0.2-0.8 parts of a coupling agent, 0.5-1.5 parts of an ultraviolet light absorber, 1-10 parts of a flame retardant, 10-30 parts of a defoaming agent, 10-30 parts of an organosilicon fabric finishing agent and 30-40 parts of a curing agent. The projector curtain is resistant to dirt, anti-bacterial, crease-resistant and good in winkle recovery performance, and the technical problems that existing curtains easily crease and are difficult to recover and not resistant to dirt, the viewing effect is affected and the service life is short are solved.

Description

technical field [0001] The invention relates to the technical field of projector equipment for teaching, in particular to a projector screen and a manufacturing method thereof. Background technique [0002] At present, school teaching uses projection technology. Projection technology is to project the light emitted by the projector onto the projection screen, form an image on the projection screen, and then reflect the light to the human eye. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. [0003] Existing projection screens can be generally divided into reflective and transmissive types in terms of function; the reflective type is used for front projection, and the transmissive type is used for rear projection; front projection screens are divided into flat screens and arc screens; Can be divided into glass curtain, metal curtain, embossed plastic curtain and so on. Generally speaking, the picture effect o...
