Problems solved by technology

Banana fiber can be divided into banana stem fiber and banana leaf fiber. Banana stem fiber has the advantages of general hemp fiber, such as high strength, small elongation, thick and hard fiber, easy moisture absorption and release, and easy dyeing. Banana leaf fiber has Excellent resistance to alkali, phenol, formic acid, chloroform, acetone, adding it to polyvinyl ch

Example Embodiment

[0013] A polyvinyl chloride foam tube with super temperature difference resistance and not brittle, prepared from the following parts by weight (kg) of raw materials: banana leaf 25, polyamide fiber 3.2, 0.4% borate coupling agent 1, azodimethyl Amide 1.5, sodium bicarbonate 5, cadmium stearate 0.5, tailings 2.8, zinc oxide 0.2, carbon black 1.2, clay 7, sodium lignosulfonate 0.3, sodium stearate 0.3, zinc borate 0.6, organic bentonite 1.2, Triphenyl phosphate 2, polyvinyl chloride 100, appropriate amount of deionized water.

[0014] The polyvinyl chloride foamed tube with super temperature difference resistance and not brittle is prepared by the following specific steps:

[0015] (1) After the banana leaves are cleaned and dried, the banana fiber is extracted by pressing, bleaching, washing, and drying, and then the banana fiber and polyamide fiber are blended and slivered to obtain a mixed fiber strip for use; add the mixed fiber strip to To 16 times the amount of absolute ethan...

Abstract

The invention discloses a super temperature difference resistant non-brittle polyvinyl chloride foam tube, which is prepared from the following raw materials (by weight): 25-28 parts of banana leaf, 3.2-3.5 parts of polyarmide fiber, 1-1.5 parts of 0.4% boric ester coupling agent, 1.5-2 parts of azodicarbonamide, 5-6 parts of sodium bicarbonate, 0.5-0.7 part of cadmium stearate, 2.8-3.2 parts of mill tailings, 0.2-0.3 part of zinc oxide, 1.2-1.4 parts of carbon black, 7-9 parts of pottery clay, 0.3-0.4 part of sodium lignin sulfonate, 0.3-0.4 part of sodium stearate, 0.6-0.8 part of zinc borate, 1.2-1.5 parts of organobentonite, 2-3 parts of triphenyl phosphate, 100-110 parts of polyvinyl chloride and a proper amount of deionized water. The prepared tube has stable quality, smooth surface, good strength, high and low temperature difference resistance, non-brittle property and cracking resistance. The preparation technology is energy-saving, economic and environmental friendly.

Description

technical field [0001] The invention relates to the technical field of foamed polyvinyl chloride, in particular to a polyvinyl chloride foamed pipe with super temperature difference resistance and not brittle. Background technique [0002] The pipeline that conveys gas in the exhaust equipment is called the air duct, which connects various equipment or components in the system into a whole. Ducts are usually made of a smooth surface material such as polyvinyl chloride pipe. Polyvinyl chloride is one of the five general-purpose plastics and is widely used in many industries such as building materials and packaging. Polyvinyl chloride foam materials are more popular due to their light weight, heat insulation, sound insulation, high specific strength, and insulation. However, while the cost of foam materials is reduced, the mechanical properties are reduced, which greatly limits the use of PVC. Application of foam materials. In "Research on Polyvinyl Chloride-Montmorillonite...
