High-strength plastic material composition and preparation method of high-strength plastic bottle

Abstract

The invention discloses a high-strength plastic material composition and a preparation method of a high-strength plastic bottle. The composition comprises high-density polyethylene, polyvinyl chloride, methyl tin mercaptide, acrylic acid, MBS (Methyl methacrylate-Butadiene-Styrene) resin, calcium carbonate and barium stearate, wherein relative to 100 parts by weight of high-density polyethylene, the content of polyvinyl chloride is 30-70 parts by weight, the content of methyl tin mercaptide is 0.1-1 part by weight, the content of acrylic acid is 1-5 parts by weight, the content of the MBS resin is 5-15 parts by weight, the content of calcium carbonate is 10-40 parts by weight, and the content of barium stearate is 0.5-3 parts by weight. By virtue of the design, the composition is high in strength and cannot rupture easily, and the loss during transportation is greatly avoided.

Description

technical field [0001] The invention relates to the field of production and preparation of plastic bottles, in particular to a high-strength plastic material composition and a preparation method of a high-strength plastic bottle. Background technique [0002] Plastic bottles are widely used in daily life because of their relatively low cost and the availability of different plastic types according to different fields, so they can be widely used in containers of various materials, for example, they can be used to hold food, It can also be used to hold detergent, etc. In the actual use process, the family packaging of many products is often more cost-effective and relatively lower in cost, so it is easier to be loved by consumers, and the weight of family packaging is often heavy. Larger tests, plastics with lower strength are often prone to breakage due to their heavy weight, especially when they are dropped to the ground. [0003] Therefore, it is an urgent problem to be s...

Problems solved by technology

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem that the plastic material in the prior art tends to be overweight due to the heavy items contained therein, which in turn leads to the problem that it is very easy to break, especially when it falls to the ground. Thereby providing a high-strength plastic material composition and a preparation method for high-strength plastic bottles that are not easy to break and greatly avoid loss during transportation
