Abstract

An environment-friendly multi-functional stabilizer and its preparation method. Glucose, dextrin and starch are added to water and stirred evenly to obtain a polymer colloid; after the polymer colloid is heated, a coupling agent is added dropwise under stirring, and a stable agent. In the present invention, the H+ in the unsaturated hydrocarbon is replaced by SiO through a coupling agent 2 Instead, through continuous reaction, a Si-O tetrahedral stable structure is formed, which increases the wear resistance and erosion resistance of the product. The generated polymer gel uses water as the dispersion medium and does not contain organic solvents. The reaction speed is fast, energy saving and environmental protection. The colloid formed after the reaction is non-toxic and harmless, which overcomes the problems of toxicity and harm of the existing phenolic resin, long production cycle, high cost, energy consumption and pollution, and inconvenient use.

Description

A kind of environment-friendly multifunctional stabilizer and preparation method thereof technical field The present invention relates to a kind of stabilizer, be specifically related to a kind of environment-friendly multifunctional stabilizer and preparation method. Background technique [0002] Existing stabilizer has shortcomings: high reaction temperature, energy consumption. The structure is complex, and a large amount of The phenolic structure can only be obtained with a large amount of formaldehyde, and the production and use process have the discharge of toxic and harmful substances, which are harmful to the environment and the human body. With great damage (provide phenolic resin literature), it was invented by German Bakelite, the developer. Environmentally friendly multifunctional stabilizer is based on plant The extract is used as the raw material, which is non-toxic and harmless, with low reaction temperature and energy saving. No toxic and harmful subst...
