Problems solved by technology

[0003] In practical applications, the plasticity of PVC materials is the main characteristic of PVC materials and the key to the application of PVC materials. However, the density of PVC materials used in traditional technologies is relatively high, and the torque is small, which seriously affects the application of PVC materials. The production of PVC materials in technology can not only reduce environmental pollution, but also cause harm to the environment

Embodiment 1

[0016] Embodiment 1. A PVC material with low density and high plasticity of the present invention is prepared from the following raw materials in proportions by weight: 65-85 parts of PVC resin, 10-18 parts of red mud, and 5-9 parts of microbeads , 2-4 parts of stabilizer, 0.5-1.5 parts of yellow foaming agent, 2-4 parts of foam regulator, 0.2-0.5 parts of phthalic acid diester, 0.1-0.2 parts of di-n-butyl phthalate, 0.05-0.1 part of diisodecyl phthalate, 0.02-0.1 part of diisononyl phthalate.

Embodiment 2

[0017] Embodiment 2, as a more accurate proportion by weight: 70-80 parts of PVC resin, 12-16 parts of red mud, 6-8 parts of microbeads, 2.5-3.5 parts of stabilizer, 0.75-1.25 parts of yellow foaming agent , 2.5-3.5 parts of foam regulator, 0.3-0.4 parts of phthalic acid diester, 0.13-0.17 parts of di-n-butyl phthalate, 0.075-0.0.09 parts of diisodecyl phthalate, ortho 0.05-0.07 parts of diisononyl phthalate.

Embodiment 3

[0018] Example 3, the specific weight ratio is: 75 parts of PVC resin, 14 parts of red mud, 7 parts of microbeads, 3 parts of stabilizer, 1.0 parts of yellow foaming agent, 3 parts of foam regulator, phthalic acid 0.35 part of diester, 0.15 part of di-n-butyl phthalate, 0.08 part of diisodecyl phthalate, and 0.06 part of diisononyl phthalate.

[0019] Through the correlation performance of traditional PVC material, embodiment 1, embodiment 2 and embodiment 3, the experimental comparison is made, and the relevant data are as shown in table 1:

[0020]

[0021] It can be seen from the relevant data in Table 1 that when taking 75 parts of PVC resin, 14 parts of red mud, 7 parts of microbeads, 3 parts of stabilizer, 1.0 parts of yellow foaming agent, 3 parts of foaming regulator, phthalic acid When 0.35 parts of diester, 0.15 parts of di-n-butyl phthalate, 0.08 parts of diisodecyl phthalate, and 0.06 parts of diisononyl phthalate, the PVC material obtained has the highest stren...

Abstract

The invention relates to the field of application of industrial slag, in particular to a PVC material with low density and high plasticity. The PVC material is prepared from the following raw materials in parts by weight: PVC resin, red mud, micro-beads, a stabilizer, a yellow foaming agent, a foaming regulator, diester phthalate, di-n-butyl phthalate, di-iso-decyl phthalate, di-isononyl phthalateand 2, 2, 4-trimethyl-1, 3-pentanediol diisobutyrate. According to the method, a large amount of red mud is utilized, recycling of industrial waste residues is achieved, and pollution of industrial slag to the land is reduced. In addition, the micro-beads are aluminosilicate fine micro-beads (sinking beads) of superfine coal ash which are globally distributed, continuous in particle size distribution, superfine and solid, have a loose and porous structure, and can be added into the PVC material as a raw material to achieve the purpose of reducing the dead weight through the physical characteristics of the micro-beads.

Description

technical field [0001] The invention relates to the application field of industrial slag, in particular to a PVC material with low density and high plasticity. 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. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products. [0003] In practical applications, the plasticity of PVC materials is the main characteristic of PVC materials and the key to the application of PVC materials. However, the density of PVC mater...
