Problems solved by technology

However, compared with other polymer resin materials, since PVA resin cannot be melt-spun, its application range is greatly limited.
[0004] Chinese patent CN102776597 relates to a high-strength and high-modulus polyvinyl alcohol fiber and its melt-spinning method, which can be melt-extruded, but the PVA powder uses water as a plasticizer to add polyols, which still belongs to the solution spinning method in essence, but uses water as a solvent , and because of the low boiling point of water, the production and instability
[0005] At present, the prior art mentions the modification of polyols and oligomers, but a large amount of water is still used as a solvent, and the origin of polyols and oligomers is not explained, and its practicability cannot be judged

Abstract

The invention discloses starch-based melt-spinning resin and application thereof. The starch-based melt-spinning resin is prepared from, by weight, 15-65 parts of starch, 35-85 parts of PVA, 20-45 parts of a plasticizer, 1.0-2.5 parts of a decomposition inhibitor, 0.5-5 parts of a fluorocarbon active agent and 1.0-10 parts of a processing aid. By modifying a starch PVA system, the melting point and decomposition point distance of the starch PVA system is increased, the initial thermal decomposition temperature is increased, the melt index is increased, the migration of a small molecule plasticizer is inhibited, and the obtained starch-based melt-spinning resin has complete biodegradation characteristics. The resin is used for preparing a non-woven fabric through a melt-spinning method, theprocess is simple, the equipment investment is low, no organic solvent nor coagulation bath is used, energy is saved, and environmental pollution caused by three wastes does not occur.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a starch-based melt-spinning resin and its application. Background technique [0002] In recent years, with the improvement of people's awareness of environmental protection, it is imminent to develop biodegradable packaging materials to solve the white pollution caused by the discarded ordinary plastic packaging. Starch-based plastics have attracted extensive attention due to their biodegradability and recycling of raw materials. If the melt spinning process can be realized, its application range will be greatly expanded. At present, there is no report about the melt spinning of starch-based resin and the compound system of starch and PVA. [0003] Due to its good biodegradability, PVA (polyvinyl alcohol) has broad application prospects in solving the white pollution caused by the waste of plastic products. However, compared with other polymer resin materials, PVA ...
