Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that in the above-mentioned PVC shoe sole formula, the content of PVC is relatively high, and the main component of curing agent E51 is epoxy resin, and both PVC and epoxy resin are brittle materials, so PVC shoe soles are subject to Cracks are prone to occur when bending, resulting in increased defects in the PVC sole, which limits the bending strength and fracture toughness of the PVC sole

preparation example Construction

[0040] Preparation example of emulsified asphalt

[0041] As shown in Table 1, the main difference of Preparation Examples 1-3 is that the ratio of raw materials is different, wherein the emulsifier is selected from coconut oil-based imidazoline produced by Shanghai Chuxing Chemical Co., Ltd.; the base asphalt is selected from Shandong Kunda Road Material Co., Ltd. The 90# asphalt; the deionized water is selected from the industrial deionized water produced by Suzhou Aiying Environmental Protection Technology Co., Ltd.

preparation example 2

[0044] Emulsified asphalt is prepared according to the following steps:

[0045] (1) Pulverize the base asphalt and heat it to 120°C for later use;

[0046] (2) Mix emulsifier with deionized water, and heat to 70°C to obtain emulsifier solution, set aside;

[0047] (3) Mix and stir base asphalt and emulsifier solution, and obtain emulsified asphalt after cooling.

[0048] Table 1

[0049]

preparation example 4

[0051] The difference between this preparation example and preparation example 2 is that the emulsifier is selected from the alkylphenol polyoxyethylene ether produced by Taixing Hengyuan Chemical Factory.

Abstract

The application relates to the field of plastic products, and specifically discloses a PVC shoe sole and a preparation process thereof. The PVC sole is made of the following components by weight: 35-60 parts of PVC, 20-45 parts of reinforcing filler, 15-25 parts of emulsified asphalt, 5-10 parts of water-based epoxy resin, and 4-8 parts of curing agent; its preparation The process is: first emulsify the base asphalt to obtain emulsified asphalt, then mix the emulsified asphalt with water-based epoxy resin to obtain epoxy emulsified asphalt, then mix the epoxy emulsified asphalt with curing agent to obtain epoxy asphalt, and finally mix the epoxy asphalt , reinforcing filler and PVC are kneaded together to obtain PVC soles. In this application, by adding emulsified asphalt to PVC, the brittleness of the PVC sole is reduced, and the PVC sole is not easy to crack when bent, thereby improving the bending strength and fracture toughness of the PVC sole.

Description

technical field [0001] The application relates to the field of plastic products, more specifically, it relates to a PVC shoe sole and a preparation process thereof. Background technique [0002] PVC refers to a polymer polymerized from vinyl chloride monomer and is one of the most used plastics in the world. PVC has many uses, one of which is as a shoe sole material. [0003] Notification number is that the Chinese patent of CN103275425B discloses a kind of PVC sole, is made up of following components: PVC (50%-70%), CaCO 3 (5%-10%), organotin stabilizer (2%-3%), calcium-zinc composite stabilizer (0.5%-1%), DBP (20%-30%), curing agent E51 (3%-6 %), which improves the bonding strength, tensile strength and bending strength of the sole material. [0004] For the above-mentioned related technologies, the inventor believes that in the above-mentioned PVC shoe sole formula, the content of PVC is relatively high, and the main component of curing agent E51 is epoxy resin, and bo...
