preparation example 1a

[0051] Preparation example 1a, a silicone resin particle, its raw material ratio is shown in Table 1, and it is prepared according to the following steps:

[0052] S1-1: Stir vinyl silicone oil, hydrogen-containing silicone oil, anti-ultraviolet particles, silane coupling agent and hydroxyl silicone oil in a disperser for 30 minutes according to the proportion, and disperse evenly to obtain component A; mix vinyl silicone oil and platinum catalyst according to the proportion Stir with the inhibitor in a disperser for 20 minutes, disperse evenly, and obtain component B;

[0053] S1-2: Mix component A and component B according to the mass ratio of 1:1, stir and react for 20 minutes to obtain silicone resin;

[0054] S1-3: Pulverize the silicone resin with a pulverizer to obtain particles with a particle size in the range of 1-5 cm, which are transferred to a ball mill for ball milling to obtain silicone resin particles with an average particle size of 3-8 μm.

preparation example 2a～5a

[0055] Preparation examples 2a-5a, a kind of silicone resin particles, differ from preparation example 1a in that the ratio of raw materials is different, as shown in Table 1.

Abstract

The invention discloses an oil agent permeation resistant pesticide bottle and a preparation method thereof. The oil agent permeation resistant pesticide bottle is prepared from the following raw materials in parts by weight: 50-80 parts of polyethylene; 15 to 25 parts of an ethylene-vinyl alcohol copolymer; 2-5 parts of a compatilizer; 5 to 15 parts of silicon resin particles; 3-6 parts of a reinforcing agent; 1 to 3 parts of an antioxidant; the silicon resin particles are obtained by mixing and reacting a component A and a component B in a mass ratio of 1: 1 and then carrying out ball milling; the component A comprises the following raw materials in parts by weight: 30-60 parts of vinyl silicone oil; 5 to 20 parts of hydrogen-containing silicone oil; the component B comprises the following raw materials in parts by weight: 20-30 parts of vinyl silicone oil; 5-10 parts of a platinum catalyst; 0.001 to 0.01 part of an inhibitor; in a mixed system of the component A and the component B, the molar ratio of silicon-hydrogen bonds to vinyl is (2-3): 1. The pesticide bottle prepared by the invention has relatively good strength performance and oil penetration resistance.

Description

technical field [0001] The invention relates to the field of plastic packaging containers, in particular to a pesticide bottle resistant to oil agent penetration and a preparation method thereof. Background technique [0002] Due to the advantages of light weight, strong sealing, stable performance and low price, plastic pesticide bottles have gradually replaced glass and other material containers and become the mainstream pesticide packaging containers. [0003] The base materials of pesticide bottles are generally polyethylene, polypropylene and polyethylene terephthalate, etc., which have good processing performance, and can be prepared by blow molding, injection molding and other processes to meet various use requirements. bottle. However, the above-mentioned substrates have poor barrier ability to oily solvents in pesticides, which is not conducive to ensuring the stability of pesticides during storage. Contents of the invention [0004] The application provides a p...
