Embodiment Construction

[0020] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] A kind of environment-friendly PVC film of the present invention, according to mass ratio, comprises: PVC 85 parts, DOP 42 parts, calcium carbonate 3 parts, stabilizer 2.5 parts, soybean oil 6 parts, TiO 2 1 part and 0.3 parts of pigments, also including PVC mass fraction 0.6% graphene, 0.7% protein powder, 2.5% urea, 0.3% hydroxypropyl methylcellulose, 1.5% low-second nitrocellulose, 3.5% of catechins.

[0022] Graphene has super high surface hardness, when evenly distributed in PVC film, it can provide super high wear resistance on product surface.

[0023] Protein powder has air-moisture conductivity, which can give it the function of breathability and moisture absorption.

[0024] Urea has the functio...

Abstract

The invention provides an environment-friendly PVC film and a preparation method thereof. The environment-friendly PVC film comprises, by mass, 80 to 90 of PVC, 40 to 45 of DOP, 2 to 5 of calcium carbonate, 2 to 3 of a stabilizing agent, 5 to 10 of soybean oil, 0.5 to 2 of TiO2 and 0.2 to 0.4 of pigment. The preparation method comprises the following steps: preparing the above substances according to the above ratio and then carrying out uniform mixing under stirring at a rotating speed of 1300 to 1400 rpm; carrying out internal mixing at 140 to 150 DEG C for 4 to 5 min and refining at 160 to 170 DEG C for 6 to 7 min; and then carrying out cooling to 150 to 160 DEG C and successively carrying out extrusion, filtering, calendaring, warm processing, cooling and setting, and trimming. The preparation method is environment friendly and free of pollution; and the PVC film prepared in the invention is durable and has long service life.

Description

technical field [0001] The invention belongs to the technical field of PVC films, and in particular relates to an environment-friendly PVC film and a preparation method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC in English (Polyvinyl chloride polymer = PVC molecular structure), is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator, and is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure and a small degree of branching. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it starts to soften at 80-85°C, and becomes viscoelastic at 130°C , 160 ~ 180 ℃ began to change into...
