Problems solved by technology

The disadvantage is that the equipment is not as good as steel pipes. During construction, special attention should be paid to the safe distance of thermal heating, and it cannot be exposed to sunlight in the air, and it is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.

Embodiment 1

[0016] A corrugated pipe for prestressed concrete, which is composed of the following raw materials in parts by weight (kg):

[0017] High-density polyethylene 85, white mineral oil 0.8, masterbatch 0.3, 3-glycidyl etheroxypropyl trimethoxysilane 1, dioctyl sebacate 2, acryl alcohol 1, trichloroisocyanuric acid 0.7, Ammonium octamolybdate 0.2, antimony trioxide 2, potassium silicate 3, marble powder 4, composite filler 10;

[0018] Described composite filler is made up of the raw material of following weight part:

[0019] Pyrophyllite 24, attapulgite 16, jade 3, polydimethylsiloxane 0.6, bis-imidazolidinyl urea 2, eucalyptus oil 1, oxidized polyethylene wax 2;

[0020] Mix the above-mentioned pyrophyllite, attapulgite and jade, ball mill evenly, add oxidized polyethylene wax, keep stirring at 120°C for 3 minutes, lower the temperature to 50°C, add polydimethylsiloxane, stir and disperse at 1000 rpm After 13 minutes, add bis-imidazolidinyl urea and eucalyptus oil in sequence...

Abstract

The invention discloses a corrugated pipe for prestressed concrete. The corrugated pipe is characterized by comprising the following raw materials in parts by weight: 80-85 parts of high-density polyethylene, 0.8-1 part of white mineral oil, 0.2-0.3 part of color master batch, 1-2 parts of 3-glycidoxy propyl trimethoxy silane, 2-3 parts of sebacic acid di-n-octyl ester, 1-2 parts of allyl alcohol, 0.7-1 part of trichloroisocyanuric acid, 0.1-0.2 part of ammonium octamolybdate, 1-2 parts of antimony trioxide, 2-3 parts of potassium silicate, 3-4 parts of marble powder and 5-10 parts of composite filler. The corrugated pipe is environment-friendly and heavy in mass, the defects that the current polyethylene corrugated pipe is light in mass and easy to float in concrete construction can be relieved, and the corrugated pipe has good tensile strength and ring stiffness.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a corrugated pipe for prestressed concrete. Background technique [0002] PVC pipe (UPVC pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and is extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. UPVC pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of UPVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic piping is used in applications for conveying potable water, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. [0003] PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. The former is suitable for transporting gaseous artificial gas, natur...
