Embodiment 1

[0039] Embodiment 1: a plastic corrugated pipe, refer to figure 1 , its components and their parts by weight are shown in Table 1. Wherein, the particle size (ie outer diameter) of the flame retardant capsule is 4±1mm, the flame retardant capsule comprises an inner core 2 and a silica gel layer 1 covering the inner core 2, and the inner core 2 is composed of powdery chalazine 201 and powdery effervescent tablets 202 according to The weight ratio is 4:1, and the silica gel layer 1 is formed by enclosing silica gel hemispheres 101 with a softening point above 300°C.

[0040] The preparation steps of the flame retardant capsule are as follows: filling the hollow silica gel hemisphere 101 with powdery cholestyramine 201 and powdery effervescent tablets 202 of corresponding weight, and then filling two pieces of silica gel hemispheres 101 with cholerite 201 and effervescent tablet 202 Cover each other to form a sphere, and use inorganic high temperature adhesive (JL-767B 1460 degr...

Embodiment 2～3

[0050] Examples 2 to 3: a plastic corrugated pipe, which is different from Example 1 in that its components and parts by weight are shown in Table 1.

[0051] Each component and its parts by weight in the embodiment 1-3 of table 1

[0052]

Embodiment 4

[0053] Embodiment 4: a plastic corrugated tube, the difference from Embodiment 1 is that the inner core 2 is formed by mixing the powdery bile alum 201 and the powdery effervescent tablet 202 with a weight ratio of 5:1.

Abstract

The invention relates to the field of plastic products, and particularly discloses a plastic corrugated pipe and a preparation method thereof. The raw materials of the plastic corrugated pipe comprise the following components in parts by weight: 80-100 parts of HDPE; 50 to 60 parts of polypropylene; 3-6 parts of talcum powder; 3-5 parts of a coupling agent; 5-10 parts of color masterbatch; 20-35 parts of a flame retardant capsule; the flame-retardant capsule comprises an inner core and a silica gel layer wrapping the inner core, and the inner core is composed of chalcanthite and effervescent tablets; the preparation method comprises the following steps: feeding, extruding, forming, spraying, cutting and conveying. The plastic corrugated pipe provided by the invention has the advantages of high flame retardance and fire protection.

Description

technical field [0001] The present application relates to the field of plastic products, and more particularly, to a plastic corrugated pipe and a preparation method thereof. Background technique [0002] Corrugated pipe refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and expansion. According to different materials, it can be divided into metal corrugated pipes and plastic corrugated pipes. Among them, plastic corrugated pipes are the main products on the market. Corrugated pipes are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries, and plastic corrugated pipes have an irreplaceable role in media transmission, power threading, machine tools, home appliances and other fields. [0003] In the Chinese invention patent publication number CN110193953B, a processing technology of a plastic corrugated pipe is disclosed, which includes the f...
