Abstract
The invention discloses an acrylic acid copolymerized polyvinyl chloride pipe for water supply and a preparation method thereof. The preparation method comprises the following steps that acrylic resinand polyvinyl chloride are placed in a polymerization kettle, the acrylic resin and the polyvinyl chloride are mixed and placed in a pre-polymerization kettle, the pre-polymerization kettle is a vertical stainless steel polymerization kettle, a turbo-type flat paddle stirrer is arranged in the pre-polymerization kettle, and the; wherein the stirring speed is controlled to be 50-250 rpm, then themixed material is placed from the pre-polymerization kettle into a post-polymerization kettle, the post-polymerization kettle is a horizontal kettle and is internally provided with a stirrer which isformed by combining three helical ribbons and is used for stirring at a low speed, and the rotating speed of the horizontal kettle is 6-7 rpm; the AGR pipe manufactured through the method is simple and convenient in process, complex process steps are reduced, meanwhile, the product quality is improved, the occurrence frequency of defective products is reduced, installation and construction are convenient, the AGR pipe does not need to consider the influence of thermal expansion and cold contraction on the pipe, and construction can be conducted all the year round, in a high-temperature area and in a cold area.
Description
technical field [0001] The invention belongs to the technical field of AGR pipes, and in particular relates to acrylic acid copolymerized polyvinyl chloride pipes for water supply and a preparation method thereof. Background technique [0002] The AGR tube is a new type of material made of ultra-fine particles of acrylic (acrylic resin) elastomers that are fully combined with polyvinyl chloride molecules in a chemical copolymerization manner. Advantages, with excellent impact resistance and low temperature resistance, it is called "plastic steel pipe". [0003] Existing AGR pipes are time-consuming and labor-intensive in the manufacturing process, often require a long time and energy, and at the same time require more process steps and more labor to complete the production, which not only increases the economic cost, but also produces The performance of the AGR pipe is lacking, and there may be many defective products, which increases the difficulty of the work. Therefore, ...
