Problems solved by technology
[0002] my country is a large agricultural country, and the annual demand for pesticides is very large; for a long time, liquid pesticides are mainly packaged in glass bottles; but glass bottles also have the following problems: 1. Glass pesticide bottles are damaged from factory to farmer use. The rate generally reaches 10-20%, and it is easy to be damaged; 2. The tare weight of glass bottles is heavy, which increases the transportation cost; in order to improve the problems of pesticide bottles, after the 1990s, plastic materials were gradually used to replace glass packaging bottles
[0004] In view of the above-mentioned related technologies, the multi-layer co-extrusion bottle is composed of a variety of resins with barrier properties, which has a good barrier effect, but during transportation, the pesticide bottle is under too much pressure or falls, which may easily cause damage to the pesticide bottle , the strength needs to be improved

preparation example 1
[0064] Preparation example 1: a kind of anti-cracking agent, included concrete component and weight are as shown in table 2, are made by following steps:
[0065] (1) Add deionized water and rubber powder into the stirring tank and stir at a stirring speed of 800r / min; obtain the first mixture after stirring evenly;
[0066] (2) Mix the first mixture with the acrylic emulsion, control the temperature to 55° C., and stir at a stirring speed of 1000 r / min, and obtain an anti-cracking agent after stirring evenly.
preparation example 2
[0067] Preparation example 2: a kind of anti-cracking agent, included concrete component and weight are as shown in table 2, are made by following steps:
[0068] (1) adding deionized water, bamboo fiber, and rubber powder into the mixing tank and stirring, the stirring speed is 900r / min, and the first mixture is obtained after stirring;
[0069] (2) Mixing and stirring the acrylate emulsion and the maleic anhydride grafted polyolefin in another stirring tank, the stirring speed is 900r / min, and the second mixture is obtained after being uniformly stirred;
[0070] (3) Mix and stir the first mixture and the second mixture, raise the temperature to 55° C., control the stirring speed to 1200 r / min, and obtain the anti-cracking agent after stirring evenly.
preparation example 3
[0071] Preparation example 3: a kind of anti-cracking agent, and the difference of preparation example 2 is that the weight of each component is different, and the concrete component that comprises and weight are as shown in table 2.

Abstract
The invention relates to the technical field of pesticide packaging, and particularly discloses a pesticide bottle and a preparation method thereof. The pesticide bottle comprises, by weight, an inner layer, a first bonding layer, a middle layer, a second bonding layer and an outer layer from inside to outside; the inner layer comprises the following raw materials by weight: 20-25 parts of HDPE, 3-5 parts of PE, 2-3 parts of a reinforcing agent, 3-5 parts of an anti-cracking agent, 0.5-1 part of wollastonite, 0.1-0.2 part of a dispersing agent, 1-2 parts of calcium carbonate and 0.3-0.5 part of a titanate coupling agent; the reinforcing agent is prepared from titanium dioxide, alginate fiber and coconut fiber; the preparation method comprises the following steps of: respectively mixing the raw materials of the inner layer, the raw materials of the middle layer, the raw materials of the first bonding layer, the raw materials of the second bonding layer and the raw materials of the outer layer, and uniformly mixing the materials to obtain an inner layer material, a middle layer material, a first bonding layer material, a second bonding layer material and an outer layer material; subjecting the raw materials of all the layers to melt extrusion and then conducting blow molding, cooling shaping and external renovation to obtain the pesticide bottle. The pesticide bottle has the advantage of being high in strength.
Description
technical field [0001] The application relates to the technical field of pesticide packaging, in particular to a pesticide bottle and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and the annual demand for pesticides is very large; for a long time, liquid pesticides are mainly packaged in glass bottles; but glass bottles also have the following problems: 1. Glass pesticide bottles are damaged from factory to farmer use. The rate generally reaches 10-20%, and it is easy to be damaged; 2. The tare weight of the glass bottle is heavier, which increases the transportation cost; in order to improve the problems of pesticide bottles, after the 1990s, plastic materials were gradually used to replace glass packaging bottles. [0003] At present, most plastic bottles for pesticides are mainly produced by multi-layer co-extrusion blow molding method, and the obtained pesticide bottles are multi-layer co-extrusion bottles; common...
