Production method of camellia oleifera meal protein adhesive

Abstract

The invention discloses a manufacturing method of an oil-tea camellia meal protein adhesive. The manufacturing method comprises the following steps of 1, oil-tea camellia meal protein powder preparation comprising processes of degreasing oil-tea camellia meal through petroleum ether, wherein the oil-tea camellia meal is subjected to oil expression, adding water and cellulase into the degreased products to carry out enzymolysis, carrying out enzyme destruction, carrying out extraction, centrifugal separation and pH value adjustment, collecting precipitates and drying in a vacuum to obtain a desired product, 2, oil-tea camellia meal protein pretreatment and grafted protein preparation comprising processes of pretreating the prepared oil-tea camellia meal protein powder by a urea solution and ethanol and adding maleic anhydride into the pretreated products to obtain a grafted protein by reaction, 3, preparation of an initiator solution having concentration of 0.7%, and 4, final product preparation comprising processes of filling nitrogen into a reactor where the grafted protein is produced, adding vinyl acetate (VAc) and the initiator solution obtained by the step 3 into the reactor under a nitrogen atmosphere for a reaction, wherein the addition of VAc and the initiator solution is completed in 2 to 3 times, then adding carbinol and a modified chitosan metal complex mildew inhibitor into the reaction product to obtain the oil-tea camellia meal protein adhesive. The manufacturing method has the advantages that the prepared oil-tea camellia meal protein adhesive has characteristics of low cost, fast procuring speed and strong mildew resistance; raw materials are abundant relatively; and economic benefits are significant.

Description

technical field [0001] The invention relates to a production method of an adhesive, in particular to a production method of an adhesive used as a bamboo and wood adhesive with camellia oleifera protein as a core raw material. Background technique [0002] Adhesives produced from vegetable protein mostly use soybean protein. Soybean is rich in fat and protein. It can be used as both food and delicacy. It can be used to extract edible oil and refine artificial gasoline. Soybean oil meal can be used as livestock feed and There are many ways to use and re-use the tofu, and the value is high, so the soybean raw material is scarce and the price rises. Two patents, CN102002338 "Preparation Method of Water-resistant Soybean Protein Adhesive" and CN101255328 "Method for Producing Modified Soybean Protein Adhesive", both belong to the example of using soybean protein as raw material to prepare adhesives. Compared with soybeans, the camellia oleifera after oil extraction has not been ...
