Problems solved by technology

However, the strength of vinyl chloride plastics such as tensile strength and bending strength is low, and its tensile strength is usually not more than 35MPa, and its bending strength is usually not more than 60MPa, so it is easy to break, and a separate vinyl chloride plastic is also easily corroded. Corrosion and fatigue resistance are also lower

Embodiment Construction

[0029] A method for making a glass fiber reinforced hard polyvinyl chloride plastic cable duct, comprising the steps of:

[0030] Step 1, mixing 5-30 parts by weight of glass fibers with 0.1-1.0 parts by weight of coupling agent KH-550 for surface treatment to obtain treated glass fibers;

[0031] Step 2, combine the treated glass fiber with 100 parts by weight of SG-5 type PVC resin, 5-10 parts by weight of nanometer calcium carbonate powder, 2-5 parts by weight of tribasic lead sulfate, 1-3 parts by weight of dibasic Basic lead phosphite, 0.1-1.0 parts by weight of barium stearate, 0.1-0.5 parts by weight of lead stearate, 0.1-0.3 parts by weight of stearic acid and 0.1-0.5 parts by weight of paraffin wax are mixed to obtain a mixture;

[0032] Step 3: Stir and mix the mixture in a high-speed mixer for 10-20 minutes, and then extrude it in a twin-screw extruder. The barrel temperature of the extruder is controlled at 180°C, and the mold temperature is controlled at 170°C.

Abstract

The invention discloses a glass fiber reinforced rigid polyvinyl chloride plastic cable conduit and a manufacturing method thereof. The glass fiber reinforced rigid polyvinyl chloride plastic cable conduit comprises 100 parts by weight of SG-5 type PVC resin, 5-30 parts by weight of glass fiber, 5-10 parts by weight of nano calcium carbonate powder, 0.1-1.0 part by weight of a coupling agent KH-550, 2-5 parts by weight of tribasic lead sulfate, 1-3 parts by weight of dibasic lead phosphite, 0.1-1.0 part by weight of barium stearate, 0.1-0.5 part by weight of lead stearate, 0.1-0.3 part by weight of stearic acid and 0.1-0.5 part by weight of paraffin. Compared with a rigid polyvinyl chloride plastic cable conduit, the glass fiber reinforced rigid polyvinyl chloride plastic cable conduit hashigher strength, rigidity, modulus, fatigue resistance, chemical corrosion resistance and heat resistance.

Description

Technical field: [0001] The invention belongs to the field of macromolecules, in particular to a glass fiber reinforced hard polyvinyl chloride plastic cable guide and a manufacturing method thereof. Background technique: [0002] Existing cable ducts are usually made of vinyl chloride plastic. However, the strength of vinyl chloride plastics such as tensile strength and bending strength is low, and its tensile strength is usually not more than 35MPa, and its bending strength is usually not more than 60MPa, so it is easy to break, and a separate vinyl chloride plastic is also easily corroded. Corrosion resistance and fatigue resistance are also lower. Invention content: [0003] The object of the present invention is to provide a kind of glass fiber reinforced hard polyvinyl chloride plastic cable guide and its manufacture method, the glass fiber reinforced hard polyvinyl chloride plastic cable guide of the present invention has higher intensity than hard polyvinyl chlori...
