The application provides an edible enzyme cross-linking color drawing coating, a preparation method and application, and belongs to the technical field of food packaging materials, and comprises the following components in percentage by weight: 4-10% of edible connecting material, 0.1-3% of biological cross-linking enzyme, 1-6% of microcapsule natural pigment, 1-5% of enzyme activity aid, 0.1-1% of rheological modifier, 1-5% of plasticizer, and the rest is solvent; the biological cross-linking enzyme comprises one or more combinations of glutamine transaminase, laccase, tyrosinase, polyphenol oxidase, peroxidase and lysine oxidase. The biological cross-linking enzyme is used to catalyze the connecting material and the casing substrate to form a covalent bond, so that the defects of weak adhesion and easy peeling of the traditional physical adsorption type coating are fundamentally overcome, the coating is non-toxic and non-residual, conforms to the clean label trend, realizes the perfect combination of food safety and excellent processing performance, and has high industrialization value.

The present application relates to a kind of high-temperature-resistant halogen-free flame-retardant PC / PBT alloy material and preparation method thereof, belong to PC / PBT alloy material manufacturing technical field.PC / PBT alloy material includes: polycarbonate, polybutylene terephthalate, composite functional agent, ester exchange inhibitor and compatibilizer;The composite functional agent is generated by the reaction of amino-containing hybrid POSS and diisocyanate-terminated polydimethylsiloxane under the catalysis of organic tin;The amino-containing hybrid POSS is generated by substitution reaction of octaamino POSS and diphenyl chlorophosphate under the action of alkali.The composite functional agent of the present application is a multifunctional agent that integrates elastomer, composite flame retardant, dispersion carrier and support carrier.The introduction of the composite functional agent into PC / PBT alloy material improves the flame retardancy and water resistance of the alloy material, and improves the dispersibility and processing resistance of inorganic ester exchange inhibitor.
