Problems solved by technology

[0006] At present, there is no adhesive specially prepared for improving the moisture-proof performance of burning incense. The traditional method of improving the moisture-proof performance of burning incense mainly adopts the method of increasing the amount of adhesive, which will easily lead to an increase in the cost of burning incense. , and the flammability becomes worse

Abstract

The invention discloses a powdery adhesive and a preparation method thereof. The adhesive is prepared from the raw materials of plant raw materials, liquid alkaline, sodium silicate, boric acid, paraffin and water. The preparation method comprises the following step: spraying molten solid paraffin into a container filled with the raw materials by using an air compressor, wherein the temperature of compressed air is required to be higher than the melting point of the paraffin by 10 to 25 DEG C, namely, atomizing the paraffin into fine particles and mixing with other raw materials to obtain the powdery adhesive. The powdery adhesive prepared by the method has high water resistance; an incense prepared by mixing the adhesive the raw materials such as wood flour and bamboo powder and extruding the mixture through an extruder is smooth in appearance, and is free from roughness; the paraffin is molten again in the drying process of the incense, and is distributed on an adhesive layer and the surface of other plant powder, so that the moisture resistance of the incense can be improved by the hydrophobic property of the paraffin.

Description

technical field [0001] The invention relates to the technical field of incense preparation, in particular to a powdery adhesive and a preparation method thereof, so that the prepared powdery adhesive can be used to produce moisture-proof incense. Background technique [0002] Burning incense (such as mosquito coils, Buddha incense, etc.) is widely used all over the world, and adhesive is one of the main raw materials for making burning incense. The production of high-grade incense mainly uses biomass-based adhesives as adhesives, but this type of adhesive has poor water resistance, and the produced incense is prone to deformation or peeling off in a humid environment. [0003] The authorized patent with the application number 201410493776.1 discloses a preparation method of a biomass adhesive for papermaking coating, which is to add a plasticizer to the aqueous starch solution, adjust the temperature to 50-70°C, and add α-amylase, Keep warm for 20-100 minutes, then heat up ...
