Problems solved by technology

[0004] Although the existing high-barrier layered hollow products have excellent barrier properties and mechanical properties, the heat resistance of the high-barrier layered hollow products is not ideal. When used as pesticide bottles, especially double-layer blow molding machines are used. Due to the existence of a parting line at the bottom of the double-layer pesticide bottle that is blown at one time, when the temperature around the pesticide bottle is high, the pesticide bottle is prone to thermal expansion and the bottom bulges, causing the bottom of the bottle to fall off and the pesticide to leak. environmental impact

Abstract

The invention discloses a pesticide packaging bottle and a preparation method thereof. The pesticide packaging bottle contains the following components (by weight): 40-50 parts of PE resin, 8-15 partsof LLDPE, 5.5-8.5 parts of nanometer tin antimony oxide, 0.7-1.4 parts of nano titanium dioxide, 5-10 parts of modified hollow glass beads, 1-3 parts of a cross-linking agent, 0.3-0.6 part of an antioxidant, 1-3 parts of butyl stearate, 1-3 parts of a compatilizer, 1-5 parts of a plasticizer, 1-3 parts of a reinforcing agent, and 5-10 parts of zinc borate. The preparation method comprises the following steps: S1: calcination; S2: melt blending extrusion; S3: vacuum reaction; and S4: blow molding. The pesticide packaging bottle of the invention has the advantages of good heat resistance and heat insulation, and high toughness and strength; in addition, the preparation method of the invention has the following advantages: the bottom of the prepared packaging bottle has no joint line, and the bottle body and the bottom are integrated as a whole.

Description

technical field [0001] The invention relates to the technical field of pesticide packaging containers, more specifically, it relates to a pesticide packaging bottle and a preparation method thereof. Background technique [0002] At present, the traditional way of packaging pesticides is glass bottles, aluminum bottles, ordinary plastic bottles, etc. Glass bottles are heavy and easy to break, which brings many difficulties and inconveniences in packaging and transportation, and is more serious and dangerous to the environment. Larger; while the price of aluminum bottles is higher, which increases the production cost; and the mechanical properties of plastic bottles are poor, and the solution is easy to corrode the contact surface, causing it to penetrate and deform the appearance. [0003] In the prior art, you can refer to the Chinese invention patent document with the application number CN01114923.X, which discloses a high-barrier layered hollow container composition and it...
