Embodiment Construction

[0022]Mix titanium dioxide and potassium carbonate in a grinder at a molar ratio of 4.0:1.5, mix and grind for 20-30 hours to obtain a mixed powder, and then calcinate the mixed powder at a constant temperature of 700-800°C for 18-20 hours to obtain a pre-mixed powder. Modified powder blank, after the pre-modified powder blank is washed 5-10 times with hydrochloric acid with a mass fraction of 20-25%, and dried at a temperature of 80-90°C for 1-2 hours, the pre-modified powder is obtained ; Mix ethyl orthosilicate and ethanol solution with a mass fraction of 50-60% in a beaker at a mass ratio of 1:10 to 1:15, and add oxalic acid 2 to 3 times the mass of orthosilicate to the beaker , at a temperature of 40-50°C and a rotational speed of 280-350r / min, after stirring and reacting for 1-2 hours, a mixture of ethyl orthosilicate is obtained, and the mixture of ethyl orthosilicate is adjusted with ammonia water with a mass fraction of 10-18%. After the pH of the ester mixture reache...

Abstract

The invention discloses an anti-cracking thermal insulation polyethylene water delivery pipe, and belongs to the technical field of building high polymer materials. The anti-cracking thermal insulation polyethylene water delivery pipe is manufactured according to the following steps: weighing the following components in sequence in parts by weight: 50-60 parts of polyethylene resin, 2-3 parts of colorant, 7-15 parts of flame retardant, 2-3 parts of lubricant and 20-40 parts of additive; mixing polyethylene resin and a colorant in a mixer; adding a flame retardant, a lubricant and an additive into the mixer, conducting stirring and mixing under the conditions that the temperature is 70-110 DEG C and the rotating speed is 800-1000 r/min to obtain a mixture, extruding and granulating the mixture to obtain a master batch, and extruding and molding the master batch to obtain the anti-cracking thermal insulation polyethylene water delivery pipe. The obtained anti-cracking thermal insulationpolyethylene water delivery pipe has excellent anti-freezing performance and anti-cracking performance.

Description

technical field [0001] The invention discloses an anti-cracking and heat-retaining polyethylene water delivery pipe, which belongs to the technical field of building polymer materials. Background technique [0002] At present, in the pipe market, plastic pipes are developing steadily, and PE pipes, PP-R pipes, and UPVC pipes all occupy a place, among which the strong development momentum of PE pipes is the most eye-catching. PE pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. [0003] PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. Vinyl. When processing different types of PE pipes, according to the different application condition...
