Composition of emulational plastic and preparation method

Abstract

This invention provides a process for preparing an emulated plastic composite, which belongs to the field of emulated plastics. In this invention, components including polyvinyl chloride paste resin and powdered rubber with diameters in the range of 30-200nm and a gel content higher than 60% are uniformly mixed and molded to obtain the emulated plastic composite. The starting components may also include a light-storing luminescent material, which can be one or several of the following light-storing luminescent materials: silicate system, aluminate system or sulfide system. The emulated plastic composite in this invention, which comprises 1-40 portions of the luminescent material and 2-8 portions of the powdered rubber, has a high strength, a high elasticity and a good sense of quality, and can be used to prepare a wide variety of bio-emulators.

Description

technical field [0001] The invention relates to a simulated plastic composition, and furthermore, relates to a translucent, soft and elastic polyvinyl chloride paste resin composition. Background technique [0002] At present, the preparation methods of imitation products imitating the texture of living organisms at home and abroad have the following categories: the first category is made of degradable materials or water-soluble materials. Such as U.S. patents US6,174,525, US5,554,659, US5,554,658, Chinese patents 97116425.8, 94102951.4, etc., which involve products made by mixing materials such as gelatin, starch, polyvinyl alcohol, corn, etc., with flavoring agents and pigments; The second type is made of metal, wood, leather or other materials, such as U.S. Patent US5,193,299, US4,654,995, Chinese Patent 91232037.0, etc.; the third type is made of polymer synthetic materials, including polyvinyl chloride (PVC) ), SBS, SEBS, polyurethane (PU), EPDM (EPDM), EVA, polyethyle...

AI Technical Summary

Problems solved by technology

[0004] 1. The strength is not high enough

For example, in US4,214,397, due to the addition of a large amount of plasticizer in the formula, the tensile strength and other indicators of the material are greatly reduced; but if a large amount of plasticizer is not added, the texture and elasticity of the material will be far worse;

[0005] 2. The hardness is too high or too low, the permanent deformation is large, and the elongation at break is low, so the simulation effect is average, especially in terms of meat texture and elasticity, such as WO03003825;

[0006] 3. High cost, such as US20040018272, US20040018223, US5709047, US2003130407, etc., which are based on a large amount of oil-filled SEBS or SBS or silicone rubber, and the material cost is relatively high;

[0007] 4. It cannot be self-illuminated in the dark, and it is not suitable for some occasions that require materials to emit light. For example, when making fish bait, many fish have phototaxis. In order to better attract fish, some products are designed with electroluminescent devices, such as US4, 625,447 and Chinese patent 02204353.5, etc.
