Problems solved by technology

[0002] As we all know, most of the cable engineering pipes used in the market currently use CPVC, VPVC and glass steel pipes. The defects of CPVC pipes such as low rigidity, insufficient strength, easy bending deformation, and low thermal deformation temperature have seriously affected the expansion of its application range. Glass steel pipe pipes The size is large, the material is heavy, it is not easy to install and use, and because the pipe is brittle and hard, it is easy to break and the service life is short; moreover, the above-mentioned pipe has a large contact surface with the cable when passing through the cable, the frictional resistance is large, the cable skin is easily damaged, and its insulation performance is poor. The heat dissipation effect is poor, which no longer meets the needs of the development of the cable laying industry

Embodiment Construction

[0009] A glass fiber rigid communication pipe, which is composed of the following raw materials in parts by weight: Anxiety resin 38, water-soluble urea-formaldehyde resin glue 36, lead acid calcium 5, titanate coupling agent 5.5, glass Fiber 13.5, antioxidant 1.3, solvent oil 2.7, plasticizer 3.5, cobalt naphthenate 1, color masterbatch 5;

[0010] Its specific preparation method is as follows: First, mix the raw materials in the above weight parts evenly, and then carry out vacuum, boost, constant temperature and constant pressure stages. The parameters and processes of each stage are: vacuum: 0.01-0.02MPa, vacuum time: 0.6h; boost: 0.02-1.2MPa, boost time: 0.9-1.2h; constant temperature and pressure: 1.0MPa, constant pressure time: 1-2h, constant temperature: 85-90°C, and finally add the single-screw extruder , Plasticized and formed at 190-200°C, the extruded tube blank is stretched longitudinally into the rotating forming mold, then vacuum-absorbed, and stretched transver...

Abstract

The invention discloses a glass fiber rigid communication tubing, which comprises the following raw materials by weight part: 36-40 parts of benzoin resin, 35-38 parts of water-soluble urea-formaldehyde resin glue, 4-6 parts of calcium plumbite, 4.5-6.5 parts of titanate coupling agent, 12.5-14.5 parts of glass fibre, 1.2-1.4 parts of antioxidant, 2.5-3 parts of solvent naphtha, 2.5-4.5 parts of plasticizer, 0.6-1.4 parts of cobaltous naphthenate and 4-6 parts of color masterbatch. The PVC tubing formula can greatly increase the antioxidation performance of the PVC tubing, cost is low, compared with prior art, the PVC tubing is suitable for popularization and application. The PVC tubing has the advantages of high intensity and high-toughness, strong impact resistance capability, low cost of product components and large market competition.
