preparation example Construction

[0028] The preparation method of the above-mentioned polyethylene and polyvinyl chloride modified environmental protection plastic inspection well comprises the following steps:

[0029] a. Weigh polyethylene resin, 50% coupling agent in total, compatibilizer and reinforcing agent in parts by weight, stir at 60-100°C for 5-20 minutes, and then cool to 30~38°C, after granulation, get spare material I;

[0030] b. After weighing polyvinyl chloride resin, stabilizer, pigment, processing modifier, remaining coupling agent, antioxidant, light stabilizer, remaining compatibilizer and impact modifier according to parts by weight, Stirring at 110-135°C for 7-30 minutes, then cooling to 30-43°C to obtain spare material II;

[0031] c. Mix spare material Ⅰ and spare material Ⅱ for 5-15 minutes. After the temperature reaches 60-80°C, cool to 32-38°C. After cooling and molding, polyethylene and PVC modified environmentally friendly plastic inspection well.

[0032]In the preparation me...

Abstract

The invention belongs to the field of a plastic check well and a preparation method thereof, and particularly relates to a polyethylene and polyvinyl chloride modified environment-friendly plastic check well and a preparation method thereof, aiming at solving the technical problem that the existing plastic check well is poor in impact strength, sensitive to temperature and bad for ring stiffness. According to the scheme for solving the technical problems, the invention provides the polyethylene and polyvinyl chloride modified environment-friendly plastic check well, which comprises the following compositions in parts by weight: 50-150 parts of polyethylene resin, 50-150 parts of polyvinyl chloride resin, 10-30 parts of nano materials, 0.5-5 parts of pigments, 2-20 parts of a lead-free stabilizer, 1-20 parts of processing aids, 1-5 parts of a lubricant, 0.5-5 parts of an antioxidant, 0.5-2 parts of a light stabilizer, 1-25 parts of a compatilizer, 1-15 parts of an impact modifier, 1-15 parts of an enhancer, and 0.5-10 parts of a coupling agent. The environment-friendly plastic check well is good in ring stiffness, high in impact strength, low in cost and long in service life.

Description

technical field [0001] The invention belongs to the field of plastic inspection wells and preparation methods thereof, and in particular relates to polyethylene and polyvinyl chloride modified environment-friendly plastic inspection wells and a preparation method thereof. Background technique [0002] With the continuous advancement of urbanization in our country, the demand for buried sewage and drainage pipes has expanded, which has also expanded the demand for plastic inspection wells, and the performance requirements for plastic inspection wells have also increased, especially anti-corrosion. Impact strength. Ordinary extruded polyvinyl chloride (PVE) double-walled plastic inspection wells have good ring stiffness and low material cost, but poor impact strength and are sensitive to temperature. Ordinary polyethylene (PE) plastic inspection wells have good toughness, However, the ring rigidity is poor, and more materials are used to ensure the ring rigidity, which wastes...
