Embodiment 1
[0063] A polyvinyl chloride pipe for pressure-resistant drainage, in terms of mass fraction, is composed of the following components:
[0064] 80 parts of polyvinyl chloride resin;
[0065] 1 part of organotin stabilizer;
[0066] 1 part of stearic acid;
[0067] 1 copy of modified ACR;
[0068] 2 parts of titanium dioxide;
[0069] 2 parts of modified nano calcium carbonate;
[0070] Wherein the organotin stabilizer can be one of maleate, mercaptan, and thiol fatty acid salt; the polyvinyl chloride resin model is ethylene hair SG-5 resin;
[0071] The preparation method of the modified ACR in the raw material is:
[0072] (1) Preparation of seed emulsion: In terms of mass fraction, 10 parts of butyl acrylate and 5 parts of styrene were added to the reactor as monomers, and 0.5 parts of sodium dodecyl sulfate emulsifier and 0.1 part of potassium persulfate were added to initiate the reaction. agent, stir and heat up to 40 ℃~50 ℃ to prepare seed emulsion;
