preparation example Construction

[0019] A kind of highly elastic polyvinyl chloride material, its preparation method comprises the following steps:

[0020] Step 1: Add polyvinyl chloride powder, stabilizer powder small material, slip agent and dyeing agent into the high-speed mixer, start the mixer, slowly add dioctyl phthalate, epoxy soybean oil, reduce the speed, Stop mixing, discharge to cooling mixer;

[0021] Step 2: Enter the twin-screw extruder after cooling, start the twin-screw extruder, turn on the vacuum pump, after the material is extruded, it is pelletized by a pelletizer;

[0022] Step 3: air blowing, cooling, to obtain transparent particles, and finally packing;

[0023] Step 4: After passing the test, use an extruder to extrude the sample, and finally get a translucent frosted product.

[0024] Among them, the degree of polymerization of polyvinyl chloride is 2500;

[0025] Wherein, the stabilizer adopts calcium zinc stabilizer, and the form of the stabilizer is powder.

[0026] Among the...

Abstract

The invention discloses a polyvinyl chloride material with high elasticity. The polyvinyl chloride material with high elasticity is prepared by the following raw materials, by mass: 40-60 parts of polyvinyl chloride, 35-40 parts of dioctyl phthalate, 1-5 parts of epoxy soybean oil, 0.5-2 parts of a stabilizer, 0.1-0.3 part of a lubricating agent, and 0.2-0.8 part of a coloring agent. The prepared finished product of the invention has the advantages of smooth hand feeling, semi-transparent sanding, light blue, greatly improved elastic performance, difficult damage and good durability.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride material preparation, in particular to a highly elastic polyvinyl chloride material. Background technique [0002] PVC material is polyvinyl chloride, which is one of the largest plastic products in the world. It is cheap and widely used. Polyvinyl chloride resin is white or light yellow powder, which cannot be used alone and must be modified. PVC is an amorphous white powder with a small degree of branching and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastics can exhibit different physical and mechanical properties. [0003] Products made of traditional polyvinyl chloride materials have low elasticity and are prone to damage during use. Therefore, an improved technology is urgently needed to solve this problem in the prior art. Contents of the invention [0004] The object of the present invention is to provide a highl...
