Abstract

The invention discloses an ultra-large typeplasticwater towercomposite powder material, which is prepared from the following components in percentage by weight: 81 percent to 87 percent of linear low-density polyethylene resin, 6.3 percent to 7.5 percent ofstyrenic thermoplastic elastomer, 2.5 percent to 3.7 percent of polypropylene, 3 percent to 3.9 percent ofantioxidant, 0.8 percent to 1.1 percent ofviscosity modifier and 1.2 percent to 4 percent of enhancer. After various components are added in the composite formula, the ultra-large typeplasticwater towercomposite powder material provided by the invention is suitable for manufacturing a plastic water tower with the diameter being 3.5m and the height being above 5m, can realize the excellent physical and mechanical properties with the ring stiffness being larger than 10Kn / m<2>, the axial test pressure being larger than 70kN, and the lateral test pressure being larger than 30kN, has no breakage or deformation, and meets the national standard requirements of the plastic water tower.

Description

technical field [0001] The invention relates to a plastic water tower, in particular to a super-large, high-strength plastic water tower composite powder. Background technique [0002] The prior art plastic water tower is generally less than 3 meters in height, and its maximum diameter is less than 1000mm. The composite powder used is composed of high-density polyethylene resin, color masterbatch and calcium carbonate. Its main disadvantages are poor physical and mechanical properties, light weight of plastic parts, and small molding volume, which cannot meet the requirements of the manufacturing process of super-large plastic water towers. Contents of the invention [0003] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a kind of super-large plastic water tower composite powder, which is made of linear low-density polyethylene resin, styrene thermoplastic elastomer, polypropylene, antioxidant, viscosity ...
