Biogum adhesive and preparation method thereof

Abstract

The invention relates to a biological glue adhesive and a method for making the same. The method comprises the following steps that: water and sodium benzoate are mixed and heated in the proportion of 55-70:1 by weight percentage; after the sodium benzoate is entirely dissolved, alum equal to 0.8-1.2 times the weight of the sodium benzoate is added into the water, and the water is stirred to produce milky solution for standby application; in the proportion of 1:1.6-2.5 by weight percentage, sheepskin glue or bone glue is dissolved in the produced milky solution; starch equal to 1 / 10-1 / 4 of the weight of the sheepskin glue or bone glue and the sodium benzoate or sodium diacetate equal to 1 / 3-1 / 2 of the weight of the sheepskin glue or bone glue are added into the milky solution; the milky solution is stirred well and then finished products can be obtained. The biological glue adhesive solves the deficiencies that the sheepskin glue or bone glue is high in freezing point, liable to mildew and short in storage time. The biological glue adhesive has low freezing point at about 12 DEG C in summer and at about 5 DEG C in winter, and is high in bonding strength, difficult to mildew, stable in performance, easy to store, nontoxic, harmless and low in cost, which is an environmentally friendly biological adhesive.

Description

technical field [0001] The invention relates to an adhesive and a manufacturing method thereof, in particular to a bioglue adhesive and a manufacturing method thereof. Background technique [0002] Sheepskin glue is a kind of colloid made from sheepskin, sheep's horn and sheep's hoof shell. It is a pure natural biological rubber material, non-toxic, harmless, pollution-free, and has high bonding strength. Bone glue is a pure natural biological glue separated from various animal bones. It has the same properties as sheepskin glue and can be used as a substitute for sheepskin glue. [0003] However, sheepskin glue or bone glue glue has a high freezing point, is solid at room temperature, is prone to mildew, and melts with heating as it is used. Contents of the invention [0004] The purpose of the present invention is to provide a bio-glue adhesive with low freezing point, high bonding strength, not easy to mildew, non-toxic, harmless, pollution-free, long storage period an...
