Problems solved by technology

As a modified material, natural anhydrite can greatly improve the compression resistance, heat insulation and flame retardancy of polyvinyl chloride resin. However, due to the poor compatibility between natural anhydrite and the matrix, the mechanical properties of the material are not ideal. Used as a filler for organic resins

Embodiment 1

[0039] Add two kilograms of 1250-mesh natural anhydrite into a high-speed mixer, add 31 grams of stearic acid at the same time, heat up to 100°C with high-speed stirring, take it out after constant temperature for 5 minutes, and obtain modified natural anhydrite; PVC resin: modified natural anhydrite Gypsum: Titanium Dioxide: MBS Resin: PE Wax: CPE: Tri-Salt Di-Salt Composite Stabilizer: Sodium Stearate Mix in a high-speed mixer at a ratio of 100:35:10:0.5:1:14:5.7:5 5 Take it out after 10 minutes, take it off after kneading on the double rollers for 5 minutes, and then shape it on a flat vulcanizer with a pressure of 10MPa to obtain composite pipe 1#. PVC resin adopts general-purpose polyvinyl chloride resin of S-1000F and S-1050P grades. See attached table 1 for the test results of mechanical properties of composite pipe 1#.

Embodiment 2

[0041] Add two kilograms of 1250-mesh natural anhydrite to a high-speed mixer, add 30 grams of aluminate coupling agent at the same time, stir at a high speed and heat up to 100°C, take it out after constant temperature for 5 minutes, and obtain modified natural anhydrite; PVC resin : Modified natural anhydrite: Titanium dioxide: MBS resin: PE wax: CPE: Tri-salt and di-salt compound stabilizer: Polyethylene wax, according to the ratio of 100:45:3:1:1.5:15:6:4 Take it out after mixing in a high-speed mixer for 5 minutes, take it out after kneading on double rollers for 5 minutes, and then shape it on a flat vulcanizer with a pressure of 10 MPa to obtain composite pipe 2#. The test results of its mechanical properties are shown in Table 1.

Embodiment 3

[0043] Add two kilograms of 1250-mesh natural anhydrite into a high-speed mixer, add 33 grams of titanate coupling agent at the same time, stir at a high speed and heat up to 100°C, take it out after constant temperature for 5 minutes, and obtain modified natural anhydrite; PVC resin : Modified natural anhydrite: Titanium dioxide: MBS resin: PE wax: CPE: Tri-salt and di-salt compound stabilizer: Calcium stearate in the ratio of 100:15:0.5:1:8:4:0.8 at high speed Take it out after mixing in the mixer for 5 minutes, take it out after kneading on the double rollers for 5 minutes, and then shape it on a flat vulcanizer with a pressure of 10 MPa to obtain composite pipe 3#. The test results of its mechanical properties are shown in Table 1.

[0044] Schedule 1:

[0045]

[0046] It can be concluded from Attached Table 1 that 3# composite pipe has the best comprehensive performance and is the preferred solution.

Abstract

The invention relates to a polyvinyl chloride (PVC) composite electrical sleeve which comprises the following raw materials in parts by weight: 100 parts of PVC resin, 2-60 parts of natural anhydrite, 3-10 parts of titanium white, 0.01-15 parts of surface modifier, 1-20 parts of toughener, 0.5-2 parts of MBS (methyl methacrylate-butadiene-styrene) resin, 1-3 parts of PE (polyethylene) wax, 1-15 parts of stabilizer and 0.1-15 parts of lubricant, wherein the mesh number of the natural anhydrite is more than 400 meshes. The PVC composite electrical sleeve is a composite pipe made of PVC / natural anhydrite and other materials, has the advantages of high temperature resistance, high voltage resistance, high strength, shock resistance and the like, and can be used as various guide pipes for wire protection, guide pipes for wiring protection, pipes for postal service, telecommunication and network cabling and threading carriers for auxiliary electric / data transfer cables.

Description

technical field [0001] The invention relates to a polyvinyl chloride composite electrical bushing. Background technique [0002] Electrical casing is a wire pipe and pipe fitting made of PVC resin as the main raw material, added with special additives, and processed by extrusion and injection molding. It is widely used in concrete, between floors or walls in construction projects as wire protection conduits ( Concealed application), can also be used as a conduit for general wiring protection (open application) and a conduit for post and telecommunications, network wiring, electrical, data transmission auxiliary cable sheathing carrier, etc. The electrical casing has high requirements on compressive performance: it is required to be able to resist impact and withstand a pressure of more than 750N. During the concrete pouring process, it will not be broken by normal tamping impact. [0003] Electrical bushings also have high requirements for heat resistance and flame retardan...
