Embodiment 1

[0028] A composite fabric for curtain roller blinds comprises a plasma-treated base cloth and a modified polyurethane TPU film pasted on the base cloth.

[0029] Among them, the polyurethane TPU film is prepared by the following method: use a high-speed mixer to mix 75 parts by mass of non-porous polyurethane TPU, 5 parts of low-density polyethylene LDPE, and 5 parts of carbon black (particle size is 20-30nm, fluidity 26-28mm), 5 parts of titanium dioxide (particle size 10-50nm), 5 parts of nano-glass beads, 5 parts of phenyl salicylate, mixed evenly, the speed of high-speed stirring is 1500r / min, and the time is 6min Then use the casting machine to squeeze and cast to form a film. The temperatures in each zone of the casting machine are: cylinder temperature 180°C, filter screen temperature 190°C, elbow temperature 190°C, connection temperature 190°C, die head temperature 190°C.

Abstract

The invention discloses a composite cloth for a curtain roller shutter and a preparation method of the composite cloth. The composite cloth comprises a plasma-treated base cloth and a polyurethane TPUfilm attached to the base cloth, wherein the polyurethane TPU film is prepared by the following method that 70-80 parts of polyurethane TPU, 4-6 parts of low-density polyethylene (LDPE), 4-6 parts ofcarbon black, 4-6 parts of titanium oxide, 4-6 parts of nano glass micro-beads and 4-6 parts of phenyl salicylate are mixed evenly, then extruded and subjected to tape casting to form the film. By modifying the polyurethane TPU, the obtained composite cloth is soft and comfortable in hand feeling, environmental protection, shading, strong light irradiation resisting, ultraviolet protection, washing and dry-cleaning resisting and aging resistance are achieved, excellent light resistance and aging resistance are achieved, the adhesion fastness of a product is high, and the quality-guarantee service life is ten years or above. After the surface of the base cloth is activated, the modified polyurethane TPU film is composited in a hot-pressed mode, glue is not used, and thus real energy savingand environmental protection are achieved.

Description

technical field [0001] The invention relates to a cloth and a preparation method thereof, in particular to a composite cloth for curtain roller blinds and a preparation method thereof. Background technique [0002] At present, the commonly used composite fabrics for curtain roller blinds on the market are divided into coated fabrics and woven fabrics. Coated fabrics are coated on the selected fabrics by coating equipment. It takes more than two or three coats to achieve the required functional fabrics. The coating slurry on the fabrics needs to have some benzene series solvents to make the coatings The surface of the layer is smooth and smooth, and the coating slurry is composed of a variety of chemical raw materials, which cannot pass the test in terms of environmental protection, and the coated curtain roller blind is easy to age, easy to fall off after a long time, peeling off, and not durable enough for washing and dry cleaning. In the case of sunlight and high temperat...
