Abstract

The invention relates to the field of degradable materials, and discloses preparation of high-temperature water-soluble PVA particles; the dissolution temperature and decomposition temperature of PVA are close, and temperature fluctuation is not beneficial to preparation of the PVA particles. For solving the problem, PVA particles which are smooth in surface, uniform in dispersion and good in color and luster are successfully prepared, so that PVA is modified and the high-temperature water-soluble PVA particles comprises the following components and raw materials in parts by weight: 100 parts of PVA, 5-50 parts of a plasticizer, 0.3-1 part of a cross-linking agent, 1-10 parts of a thermal decomposition inhibitor, 0.5-5 parts of a thermo-oxidative aging resistant agent, and 0.1-5 parts of a lubricant.

Description

technical field [0001] The invention relates to the field of biodegradable materials, in particular to a high-temperature water-soluble PVA particle. Background technique [0002] With the waste gas produced by the development of industrialization and people's environmental pollution becoming more and more serious, energy saving and emission reduction and environmental protection are topics that people generally pay attention to. Polyvinyl alcohol (PVA) is an environmentally friendly material with excellent properties such as water solubility, good film-forming properties, high crystallinity, and high tensile strength. It is widely used in chemical separation, medical and health, optoelectronics, food packaging and One of the most versatile and important plastics in nutritional applications. However, the polyhydric structure of PVA is characterized by its hydrophilic surface, which leads to the disadvantages of insufficient water resistance and heat resistance stability, wh...
