Embodiment 1

[0015] A preparation method of an anti-ultraviolet aging PVC film material, comprising the following steps:

[0016] (1) Polyvinyl chloride, epoxidized soybean oil, titanium dioxide, pigments and antioxidants are batched according to the mass percentage of 100:1:0.2:0.08:0.3, and then stirred at a speed of 1200 rpm for 6 minutes, and stirred Uniform;

[0017] (2) Then go through the steps of banburying, rough refining and refining successively, wherein the banburying is kept at a temperature of 160°C for 4 minutes, the rough refining is kept at a temperature of 180°C for 7 minutes, and the refining is kept at a temperature of 170°C for 6 minutes;

[0018] (3) Cool down to 160°C, extrude and filter, then go through four-roll calendering, embossing and tempering, then cooling and shaping, trimming and coiling to obtain the finished product.

Embodiment 2

[0020] A preparation method of an anti-ultraviolet aging PVC film material, comprising the following steps:

[0021] (1) Mix polyvinyl chloride, epoxidized soybean oil, titanium dioxide, pigment, antioxidant, plasticizer, epoxidized soybean oil, heat stabilizer, whitening agent, calcium powder and anti-ultraviolet agent at 100:1:0.2 :0.08:0.3:25:1:5.3:0.02:40:0.4 mass percentage is carried out batching, then it is stirred 4min with the rotating speed of 1100 revs / min, stirs evenly;

[0022] (2) Then go through banburying, rough refining and refining steps in sequence, wherein banburying is kept at a temperature of 150°C for 4 minutes, rough refining is kept at a temperature of 180°C for 7 minutes, and refining is kept at a temperature of 180°C for 5 minutes;

[0023] (3) Cool down to 160°C, extrude and filter, then go through four-roll calendering, embossing and tempering, then cooling and shaping, trimming and coiling to obtain the finished product.

Embodiment 3

[0025] A preparation method of an anti-ultraviolet aging PVC film material, comprising the following steps:

[0026] (1) Polyvinyl chloride, epoxidized soybean oil, titanium dioxide, pigments and antioxidants are batched according to the mass percentage of 100:1:0.2:0.08:0.3, then stirred for 5 minutes at a speed of 1100 rpm, and stirred Uniform;

[0027] (2) Then go through banburying, rough refining and refining steps in sequence, wherein the banburying is kept at a temperature of 150°C for 4 minutes, the rough refining is kept at a temperature of 180°C for 8 minutes, and the refining is kept at a temperature of 180°C for 6 minutes;

[0028] (3) Cool down to 160°C, extrude and filter, then go through four-roll calendering, embossing and tempering, then cooling and shaping, trimming and coiling to obtain the finished product.

Abstract

The invention discloses an anti-ultraviolet aging PVC film material and a preparation method thereof. The method comprises the following steps: (1) burdening polyvinyl chloride, epoxidized soybean oil, titanium dioxide, a pigment and an antioxidant according to the mass percent of 100:1:0.2:0.08:0.3, and evenly agitating the raw materials; (2) then sequentially carrying out banburying, crude refining and refining procedures, wherein banburying is kept at 150-160 DE C for 3-4 minutes, crude refining is kept at 170-180 DEG C for 7-8 minutes, and refining is kept at 170-180 DEG C for 5-6 minutes; (3) cooling to 160-170 DEG C, extruding and filtering, and then cooling and sizing, trimming and coiling to prepare a product after four-roll calendering, embossing and blending. By adopting the anti-ultraviolet aging PVC film material prepared by the preparation method disclosed by the invention, a series of problems caused by ultraviolet light irradiation can be effectively solved.

Description

technical field [0001] The invention relates to the field of film materials, in particular to an anti-ultraviolet aging PVC film material and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the application fields of industrial textiles are becoming more and more extensive. Textile membrane structure materials, as one of the important branches of industrial textiles, are new materials that have developed rapidly abroad in recent years and are being widely used in various fields in the world. In large-scale construction projects, it is called the fifth building material after steel, cement, wood and glass. It can not only be applied to the application fields of original building materials, but also has incomparable advantages over traditional building materials in original buildings. Nowadays, as one of the most commonly used materials in membrane structure construction, PVC coated membrane has been widely used in the roo...
