High-barrier-property pesticide packing bottle and preparation method thereof

Abstract

The invention discloses a high-barrier-property pesticide packing bottle and preparation thereof. The high-barrier-property pesticide packing bottle comprises a barrier layer, an adhesion layer and abase layer which adhere to one another successively from inside to outside, the barrier layer and the base layer are separately attached to the two sides of the adhesion layer, and the thickness ratioof the barrier layer, the adhesion layer and the base layer is 1: 0.5-0.8: 2-2.5. The preparation method comprises the following steps: S1, raw material fusing; S2, double-screw extrusion forming; S3, blow molding; and S4, blow molding of the barrier layer. The high-barrier-property pesticide packing bottle has excellent mechanical property and pesticide permeation resistance, and has the advantage of good barrier property. In addition, a pesticide packing bottle prepared by the preparation method is formed integrally, the mechanical property and the pesticide permeation resistance are excellent, and the barrier property is good.

Description

technical field [0001] The invention relates to the technical field of packaging containers, in particular to a high-barrier pesticide packaging bottle and a preparation method thereof. Background technique [0002] Liquid pesticides have always been packaged in aluminum bottles and glass bottles. Aluminum bottles are expensive. The main disadvantages of glass bottles are: 1. High breakage rate. Glass bottles are generally as high as 10-20% from leaving the factory to being used by farmers, which not only pollutes the environment , and increased costs; 2. The inner plug of the glass bottle is not tightly sealed, which is easy to cause leakage; 3. The glass bottle itself is heavy, which increases the transportation cost; 4. The bottle is difficult to recycle, and it is easy to cause accidental poisoning and environmental pollution; 5. Export transportation requires effective fumigation or heat-treated wooden outer packaging. [0003] In 1992, after the former Ministry of Che...

[0002] Liquid pesticides have always been packaged in aluminum bottles and glass bottles. Aluminum bottles are expensive. The main disadvantages of glass bottles are: 1. High breakage rate. Glass bottles are generally as high as 10-20% from leaving the factory to being used by farmers, which not only pollutes the environment , and increased costs; 2. The inner plug of the glass bottle is not tightly sealed, which is easy to cause leakage; 3. The glass bottle itself is heavy, which increases the transportation cost; 4. The bottle is difficult to recycle, and it is easy to cause accidental poisoning and environmental pollution; 5. Export transportation requires effective fumigation or heat-treated wooden outer packaging

Although the existing pesticide bottle with HDPE layer has simple structure, good chemical resistance, waterproof performance and mechanical performance, it can fully adapt to the purpose of long-distance transportation and high-intensity use, but some commonly used pesticides such as toluene and xylene The diluent components easily seep out through the bottle walls
