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.

Example Embodiment

[0023] The present invention also provides a method for preparing a high-strength plastic bottle, wherein the preparation method includes:

[0024] 1) Mix MBS resin and calcium carbonate to obtain modified calcium carbonate;

[0025] 2) Mix high-density polyethylene, polyvinyl chloride, tin methyl mercaptan, acrylic acid, barium stearate, and the modified calcium carbonate prepared in step 1), and then blow-mold to obtain a high-strength plastic bottle; among them,

[0026] Relative to 100 parts by weight of the high-density polyethylene, the amount of polyvinyl chloride is 30-70 parts by weight, the amount of tin methyl mercaptan is 0.1-1 part by weight, and the amount of acrylic acid is 1 -5 parts by weight, the amount of MBS resin is 5-15 parts by weight, the amount of calcium carbonate is 10-40 parts by weight, and the amount of barium stearate is 0.5-3 parts by weight.

[0027] In a preferred embodiment, in order to further improve the strength of the prepared plastic bottle, relative to 100 parts by weight of the high-density polyethylene, the amount of the polyvinyl chloride is 40-60 parts by weight, and the methyl The amount of tin mercaptide is 0.3-0.7 parts by weight, the amount of acrylic acid is 2-4 parts by weight, the amount of MBS resin is 8-12 parts by weight, and the amount of calcium carbonate is 20-30 parts by weight. The amount of barium stearate is 1-2 parts by weight.

[0028] The mixing temperature in step 1) can be adjusted according to actual needs. For example, in a preferred embodiment of the present invention, in order to make the mixing effect better, to save production costs, and to further improve the final plastic bottle Strength, the mixing temperature in step 1) is 150-280°C.

[0029] Similarly, in another preferred embodiment, the temperature of mixing and smelting in step 2) is 180-300°C.

[0030] In a preferred embodiment, step 2) may also include adding color masterbatch for mixing and smelting, and relative to 100 parts by weight of the high-density polyethylene, the amount of the color masterbatch is 1-3 weight Copies.

[0031] In a more preferred embodiment, relative to 100 parts by weight of the high-density polyethylene, the amount of the masterbatch is 1-2 parts by weight.

[0032] The high-density polyethylene, the polyvinyl chloride and the calcium carbonate are as described above, and will not be repeated here.

Example Embodiment

[0034] Example 1

[0035] 1) Mix 8g MBS resin and 20g calcium carbonate at a temperature of 150°C to obtain modified calcium carbonate;

[0036] 2) Put 100g high-density polyethylene, 60g polyvinyl chloride, 0.7g tin methyl mercaptan, 4g acrylic acid, 2g barium stearate, 2g masterbatch and the modified calcium carbonate prepared in step 1) at temperature The high-strength plastic bottle A1 is obtained by mixing and smelting at 300°C and then blow molding.

Example Embodiment

[0037] Example 2

[0038] 1) Mix 12g MBS resin and 30g calcium carbonate at a temperature of 280°C to obtain modified calcium carbonate;

[0039] 2) Put 100g high-density polyethylene, 60g polyvinyl chloride, 0.7g tin methyl mercaptan, 4g acrylic acid, 2g barium stearate, 2g masterbatch and the modified calcium carbonate prepared in step 1) at temperature The high-strength plastic bottle A2 is obtained by mixing and smelting at 300°C and then blow molding.
