Embodiment 1

[0016] The processing modifier of the present invention is prepared by the following process procedures:

[0017] One, prepare the preparation of each component and parts by weight of the processing modifier

[0018] 1. Preparation of rubber and plastic modifier:

[0019] According to the ratio of rubber and plastic modifiers, take 1.5% of ethylene-vinyl acetate copolymer and 0.05% of aluminate coupling agent, put them into the mixer together, stir at room temperature, and discharge the material after stirring evenly. .

[0020] 2. The preparation of each component and parts by weight:

[0021] Take rubber and plastic modifier 2; ethylene glycol 79 ester 20; M-50 petroleum ester 20; chlorinated paraffin 10; foaming agent 3; organotin stabilizer 0.6, set aside.

[0022] Two. the preparation of described processing modifier:

[0023] 1. Mixing: Mix the above-mentioned components by weight, put them into a kneader and mix them evenly, heat to 135°C-140°C to stop heating, and ...

Embodiment 2

[0026] This embodiment is basically the same as Embodiment 1, the difference is that:

[0027] 1. Preparation of additives and parts by weight of each component of the processing modifier:

[0028] 1. Preparation of auxiliary rubber and plastic modifier:

[0029] Take ethylene vinyl acetate copolymer 2 and aluminate coupling agent 0.07 according to the rubber-plastic modifier ratio mentioned above, put them into the mixer together, stir at normal temperature, and discharge the material after stirring evenly. .

[0030] 2. The preparation of each component and parts by weight:

[0031] Take rubber and plastic modifier 2.2; ethylene glycol 79 ester 22; M-50 petroleum ester 22; chlorinated paraffin 11; foaming agent 3.2; organotin stabilizer 0.7, and set aside.

Embodiment 3

[0033] This embodiment is basically the same as Embodiment 1, the difference is that:

[0034] 1. Preparation of additives and parts by weight of each component of the processing modifier:

[0035] 1. Preparation of auxiliary rubber and plastic modifier:

[0036] According to the ratio of rubber-plastic modifiers, take 2.5 ethylene-vinyl acetate copolymer and 0.1 aluminate coupling agent, put them into the mixer together, stir at normal temperature, and discharge the material after stirring evenly. .

[0037] 2. The preparation of each component and parts by weight:

[0038] Take 2.5% of rubber and plastic modifier; 23% of ethylene glycol 79 ester; 23% of M-50 petroleum ester; 12.5% ​​of chlorinated paraffin; 3.5% of foaming agent;

Abstract

The invention discloses a processing modifier for polyvinyl chloride artificial leather. The processing modifier is characterized by comprising the following components in parts by weight: 2-3 parts of rubber-plastic modifier, 20-25 parts of glycol 79 acid ester, 20-25 parts of M-50 petroleum ester, 10-15 parts of chlorinated paraffin, 3-4 parts of foaming agent and 0.6-1.0 part of organic tin stabilizer. A preparation process of the processing modifier comprises: preparation of the components, mixing, stirring, heating, cooling, unloading and packaging. The processing modifier has the characteristics of novel concept, standardized process, easiness for operating, low price and environmental friendliness and the advantages of enhancing the toughness and intensity, reducing the product cost and the like when used for processing polyvinyl chloride artificial leather. The processing modifier can be produced in batch, and can be widely applied to the field of processing of polyvinyl chloride artificial leather.

Description

technical field [0001] The invention relates to a processing modifier for plastics, in particular to a processing modifier for polyvinyl chloride artificial leather. Background technique [0002] As we all know, the traditional processing modifiers used for PVC artificial leather add more auxiliary materials such as acrylates, so the produced PVC artificial leather is relatively brittle, poor in strength and toughness, and relatively high in cost, which is difficult to meet consumer needs. How to reduce the cost of producing PVC artificial leather accessories and improve the quality has become an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of above-mentioned background technology, research and develop a kind of new auxiliary agent as auxiliary material, in order to improve the strength and toughness of polyvinyl chloride artificial leather, reduce production cost, and provide a kind of ...
