Embodiment 1

[0030] Wear-resistant PVC plastic raw materials (parts by weight): 100 parts of polyvinyl chloride resin, 1.5 parts of dioctyl adipate, 1.5 parts of polyethylene wax, 3 parts of silicon powder, 0.3 parts of vinyltrimethoxysilane, and 0.03 parts of antibacterial agent , 0.06 part of heat stabilizer.

[0031] The antibacterial agent is composed of cocamidopropyl betaine, 2-butyl-1,2-benzisothiazoline-3-one, 5-chloro-2-methyl-4-isothiazoline-3- The ketone is obtained by stirring and mixing uniformly according to the mass ratio of 1:1:1.

[0032] The heat stabilizer is obtained by uniformly stirring and mixing zinc 2-ethylhexanoate, zinc laurate and zinc stearate in a mass ratio of 1:1:1.

[0033] Preparation of abrasion resistant PVC plastic:

[0034] (1) take each component according to weight ratio;

[0035] (2) Add each component into a high-speed mixer for mixing, the mixing speed is 86 rpm, and the stirring time is 13 minutes;

[0036] (3) Place the mixed material in a t...

Embodiment 2

[0038] Basically the same as Example 1, the only difference is that the antibacterial agent consists of 2-butyl-1,2-benzisothiazolin-3-ketone, 5-chloro-2-methyl-4-isothiazoline -3-ketone is obtained by stirring and mixing at a mass ratio of 1:1. Obtain the wear-resistant PVC plastic of embodiment 2.

Embodiment 3

[0040] Substantially the same as Example 1, the only difference is that the antibacterial agent consists of cocamidopropyl betaine, 5-chloro-2-methyl-4-isothiazolin-3-one in a mass ratio of 1:1 Stir to mix well. Obtain the wear-resistant PVC plastic of embodiment 3.

Abstract

The invention discloses wear-resistant PVC (polyvinyl chloride) plastic and a preparation method. The wear-resistant PVC plastic is prepared from raw materials in parts by weight as follows: 90-110 parts of PVC resin, 1-2 parts of dioctyl adipate, 1-2 parts of polyethylene wax, 1-5 parts of polyethylene wax, 0.1-0.5 parts of trimethoxysilane, 0.01-0.1 parts of an antibacterial agent and 0.01-0.1 parts of a heat stabilizer. The provided wear-resistant PVC plastic adopts a simple and stable construction process, is low in cost, has excellent mechanical property, flame resistance and antibacterial property and is resistant to aging and high temperatures and long in service life.

Description

technical field [0001] The invention relates to a PVC plastic, in particular to a wear-resistant PVC plastic and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC for short) resin is a thermoplastic polymer compound polymerized from vinyl chloride (VC for short) monomer. PVC is a white amorphous powder, non-toxic, odorless, with a small degree of molecular chain branching. Excellent physical properties, high chemical stability, good processability and plasticity. The preparation method of polyvinyl chloride is to combine acetylene (CH≡CH) with hydrogen chloride (HCl) or chlorine (Cl 2 ) reaction to produce vinyl chloride (CH 2 =CHCl) monomer, and then polymerization reaction to generate polyvinyl chloride. Free radicals bring vinyl chloride monomers together to form polyvinyl chloride resin. [0003] Polyvinyl chloride resin is a multi-component plastic. Different additives can be added according to different uses. Therefore, with diffe...
