Embodiment 1

[0026] The composition (Kg) of the dipping process formula is:

[0027] Paste PVC 100

[0028] Dioctyl phthalate 80

[0029] Cadmium stearate 3

[0030] Barium Stearate 1

[0031] Bisphenol A 0.9

[0032] When the above formula is used in the plastic dipping process, the plasticizing time is short, the plasticized surface of the product is uniform, and the product has good transparency.

Embodiment 2

[0034] The composition (Kg) of the dipping process formula is:

[0035] Paste PVC 100

[0036] Dioctyl phthalate 90

[0037] Cadmium stearate 2

[0038] Barium Stearate 2

[0039] Bisphenol A 1.8

[0040] When the above formula is used in the plastic dipping process, the plasticizing time is short, the plasticized surface of the product is uniform, and the product has good transparency.

Embodiment 3

[0042] The composition (Kg) of the dipping process formula is:

[0043] Paste PVC 100

[0044] Dioctyl phthalate 100

[0045] Cadmium stearate 5

[0046] Barium Stearate 1

[0047] Bisphenol A 2

[0048] The above formula is used in the dipping process, the plasticizing time is short, the plasticized surface of the product is uniform, the transparency is excellent, and the resistance to heat and oxygen degradation is good.

Abstract

A process formula die carving includes compositions as the follows, 100 kg polyvinyl chloride in paste state, 80-100 kg dicapryl phthalate, 1-5 kg cadmium stearate, 1-5 g barium stearate, 0.5-2 kg bisphenol A and 0.01-1 kg dyestuff. The advantage of the present invention is using paste state polyvinyl chloride as main body, suspending each composition in dicapryl phthalate uniformly, plasticizing in not high temp and having excellent antidegradability.

Description

technical field [0001] The invention relates to a composition used in a molding process. Background technique [0002] With the continuous improvement of the appearance and performance requirements of plastic products used in the hardware industry, the appearance and performance of the original plastic products prepared by injection molding technology cannot meet the requirements of users. In the process of use, the plastic products prepared by the injection molding process are not beautiful and convenient, which affects the further expansion of the application range of plastic products. Contents of the invention [0003] The purpose of the present invention is to provide a composition for dipping process. [0004] In order to achieve the above object, the present invention takes the following measures: [0005] Its composition (Kg) is: [0006] Paste PVC 100 [0007] Dioctyl phthalate 80~100 [0008] Cadmium stear...
