preparation example Construction

[0037] The preparation method of above-mentioned material, comprises the steps:

[0038] A. Treat the calcium carbonate with a coupling agent, and then dry it. The drying temperature can be, for example, 100-110° C.; the weight ratio of the coupling agent to calcium carbonate is 1-3:55-65. The coupling agent can be a silane coupling agent, such as KH550, KH570, etc.;

[0039] B, adding polystyrene, polyethylene wax, and optional antioxidant, lubricant, plasticizer and colorant in the mixture that step A obtains; Preferably, add 16~19% polystyrene, 10 ~15% polyethylene wax;

[0040] C, the mixture obtained in step B is extruded, cooled, dried and then cut into pellets;

[0041] D. Dry the pellets at a temperature of 60-80°C to obtain a composite material.

[0042]The preparation process of the material of the invention is simple and easy to operate, the raw materials are easy to obtain, and the cost is low, which is beneficial to the production and popularization of the mate...

Embodiment 1

[0045] A. 58% CaCO will be treated with a coupling agent accounting for 1.9% by weight 3 And drying, drying temperature is 100 ℃;

[0046] B, add 16% polystyrene, 14% polyethylene wax and 0.3% antioxidant 1010, 0.3% antioxidant 168, 8% paraffin, 4% ACR201;

[0047] C. Pre-mix the compound with a high-speed mixer, extrude, cool, dry and then cut into pellets;

[0048] D. Dry the mixture at a temperature of 70°C to obtain a composite material.

[0049] Take the production of 1000g material as an example, that is, dry 580g CaCO3 treated with 19gKH550 at 100°C, then add 160g polystyrene, 140g polyethylene wax, 3g antioxidant 1010, 3g antioxidant 168, 80g paraffin wax, 40g ACR201 Pre-mix with a high-speed mixer, extrude, cool, blow dry, cut into pellets, and then dry the mixture at 70°C to obtain a composite material.

Embodiment 2

[0051] A, with the 62% CaCO that accounts for the weight ratio 3% coupling agent process Drying, drying temperature is 102 ℃;

[0052] B. Add 17.5% polystyrene, 12.9% polyethylene wax and 0.3% antioxidant 1010, 0.3% antioxidant 168, 4% paraffin, 3% ACR201;

[0053] C. Pre-mix the compound with a high-speed mixer, extrude, cool, dry and then cut into pellets;

[0054] D. Dry the mixture at a temperature of 76°C to obtain a composite material.

[0055] Take the production of 1000g material as an example, that is, dry 620g CaCO3 treated with 30g KH550 at 102°C, then add 175g polystyrene, 129g polyethylene wax, 3g antioxidant 1010, 3g antioxidant 168, 40g paraffin, 30g of ACR201 is pre-mixed with a high-speed mixer, extruded, cooled, dried, and then cut into pellets, and then the mixture is dried at 76°C to obtain a composite material.

Abstract

The invention provides a material capable of automatically dispersing when encountering impact, which comprises polystyrene, polyethylene wax, calcium carbonate and a processing aid, wherein the processing aid comprises a coupling agent, an optional antioxidant, an optional lubricant, an optional plasticizer, an optional colorant and the like. Preferably, the material comprises the following components by weight percent: 16 to 19 percent of polystyrene, 10 to 15 percent of polyethylene wax and 55 to 65 percent of calcium carbonate. The material has good formability and machinability, can be manufactured into a container capable of automatically dispersing by a plastic hot melt injection moulding method and is especially processed into the cartridge case of an anesthetization bullet.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a material that can automatically disperse upon impact and its manufacturing method and application. Background technique [0002] With the continuous development of human society and the continuous improvement of civilization, the methods used by law enforcement officers to subdue criminal suspects tend to be more and more humane. For example, the use of narcotic bullets in the law enforcement process can not only relieve the criminal suspect's resistance to arrest and counterattack in the shortest time, but also avoid irreparable personal injury to the criminal suspect. [0003] The shell case of the anesthetic bullet used in the prior art is made of paper, rubber or metal copper. Among them, the density of paper is too small and the rigidity is not enough, and the bullet is easy to deviate during the flight; the rubber bullet is also unstable in flight due to too much elasticity,...
