Abstract

The invention discloses degradable high-heat-resistance jelly glue and a preparation method thereof, and the jelly glue comprises the following components in parts by weight: deionized water, industrial gelatin, glucose syrup, magnesium sulfate heptahydrate, a polylactic acid dissolving solution, sodium hydrosulfite, a defoaming agent, sodium hydrogen sulfite, a preservative and carrageenan. A main body of the jelly glue is made of biodegradable materials such as gelatin, sugar and polylactic acid, and the jelly glue is mainly used for packaging paper products, has better degradability, can be fully degraded by microorganisms in the environment after being used, and belongs to an environment-friendly adhesive. The jelly glue disclosed by the invention has excellent bonding strength and heat resistance, has relatively good bonding strength for a PP/PE plastic film with a low dyne value, and meanwhile, is relatively high in heat resistance.

Description

technical field [0001] The invention belongs to the technical field of glue, and in particular relates to a degradable high heat-resistant jelly glue and a preparation method thereof. Background technique [0002] In life and industry, all kinds of packaging are inseparable. Most of the packaging materials are made of paper products. The use of paper product packaging is very wide. The use of various paper product packaging pervades all aspects of human life and production. Paper packaging has a wide range of raw materials, low cost of ownership, light weight, and recyclable waste. It is widely used in daily chemicals, food, medicine, tobacco, health care products, gift boxes, and transportation. When paper products are discarded after use, their recycling has become the focus of research in recent years. [0003] With the improvement of requirements for packaging and printing products, there are more and more products with bright colors, strong three-dimensional effect, mo...
