Problems solved by technology

[0003] Domestic polyvinyl chloride (PVC) calendered sheet is limited by production and technology, in order to ensure processing performance and product physical properties, organotin stabilizers have been used, and organotin stabilizers have a great impact on the environment during processing, and the price High, especially in Europe and the United States recently, the heavy metal tin control requirements for imported PVC materials for children's toys are very strict. From the previous limit, it has been clearly banned now

Embodiment 1

[0027] In this embodiment, an environment-friendly polyvinyl chloride material composition comprises the following raw material components in parts by weight:

[0028] Table 1

[0029]

[0030] The preparation method of above-mentioned environment-friendly polyvinyl chloride material composition, comprises the steps:

[0031] 1) Weigh various raw material components according to the formula in the above table, and put them in order according to PVC powder → titanium dioxide, colorant → magnesium-aluminum-zinc composite stabilizer, DOTP, epoxy soybean oil → processing aid, MBS, talc powder → The hot mixer runs at low speed, and then the mixer runs at high speed. When the temperature of the material rises to 100-105°C, the material is automatically discharged into the cold mixer.

[0032] 2) In the cold mixer, the material is rapidly cooled and further mixed evenly. When the temperature of the material is cooled to 75-80°C, the material is manually discharged into the storag...

Abstract

The invention relates to an environment-friendly polyvinyl chloride material composition as well as a preparation method and application thereof. The environment-friendly polyvinyl chloride material composition is prepared from the following raw material components in parts by weight: 100 parts of polyvinyl chloride resin, 2.5 to 3.5 parts of magnesium aluminum zinc composite stabilizer, 1 to 2 parts of dioctyl terephthalate, 2 to 4 parts of epoxy soybean oil, 3 to 5 parts of processing aid, 7 to 10 parts of modifier, 2 to 15 parts of filler, and 0.01 to 0.02 part of coloring agent. The environment-friendly polyvinyl chloride material composition is environment-friendly; the physical performance of the environment-friendly polyvinyl chloride material composition is ensured, the impact resistance is excellent, and the heat shrinkable property can be improved; and the polyvinyl chloride material composition is high in smoothness, excellent in gloss, high in product quality and low in cost.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an environment-friendly polyvinyl chloride material composition and a preparation method and application thereof. Background technique [0002] With the vigorous development of electronic plastics fields such as electronics, packaging and printing, toys, etc., the application of plastic polymer materials has been popularized in various fields. With the continuous improvement of people's quality of life, higher requirements are placed on the environmental performance and safety performance of plastic polymer materials used in children's toys. Especially in European and American countries, the environmental performance requirements of children's toy materials have been significantly improved. The environmental performance requirements of polyvinyl chloride (PVC) materials are getting higher and higher. [0003] Domestic polyvinyl chloride (PVC) calendered sheet is limited by...
