Example Embodiment
[0041] Preparation examples of toughening agent 1-3
[0042] In Preparation Examples 1-3, the acrylic emulsion was selected from the td-br type acrylic emulsion sold by Shanxi Zhongyi Tuoda Construction Engineering Materials Co., Ltd., and the bisphenol A type epoxy resin emulsion was selected from the TC sold by Jiangyin Wanqian Chemical Co., Ltd. -K44 type bisphenol A general liquid epoxy resin.
Example Embodiment
[0043] Preparation Example 1: (1) According to the ratio in Table 1, weigh 5kg of deionized water, put it into the reactor, add 1kg of zinc stearate to the reactor, heat to 50°C, add 10kg of pineapple leaf fiber, 1kg of glass fiber and 1kg of coconut fiber are stirred at 400r / min until the three fibers are fully dissolved and cooled to room temperature; the pineapple leaf fiber length is 3mm, diameter is 10μm, glass fiber length is 1.5mm, diameter is 10μm , The length of coconut fiber is 10mm and the diameter is 1.5μm;
[0044] (2) Mix 1 kg of acrylic emulsion and 5 kg of bisphenol A epoxy resin and heat to 40° C., add the resultant of step (1), and stir at a rotation speed of 200 r / min to mix uniformly.

Abstract
The invention discloses a pesticide storing container and a preparation method thereof. The pesticide storing container comprises an inner layer, a bonding layer I, a blocking layer, a bonding layer II and an outer layer which are sequentially bonded from inside to outside; and the inner layer is prepared from the following components in parts by weight: 10-20 parts of HDPE, 1-5 parts of a flexibilizer, 1-5 parts of a reinforcing agent, 2-6 parts of activated nano calcium carbonate, 3-6 parts of polypropylene, and 1-5 parts of butyronitrile rubber powder. The preparation method of the pesticide storing container comprises the steps: S1, melt extrusion is conducted; S2, blow molding is conducted; and S3, trimming treatment is conducted, specifically, a semi-finished blank product is trimmed, and a finished product is prepared. The pesticide storing container has the advantages of being high in strength, good in toughness and high in falling resistance; and additionally, the preparationmethod has the advantages that the prepared pesticide storing container is good in strength, good in toughness and high in falling resistance.
Description
technical field [0001] The invention relates to the technical field of pesticide packaging containers, more specifically, it relates to a pesticide storage container and a preparation method thereof. Background technique [0002] Liquid pesticides have been packaged in aluminum bottles and glass bottles. Aluminum bottles are expensive. The main disadvantages of glass bottles are: 1. High damage rate, which not only pollutes the environment, but also increases costs; 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 Chemical Industry put forward the development strategy of "replacing glass with plastic", the plastic packaging industry has developed rapidly, among which PET bottles and HDPE bottles ...
