Abstract

The invention discloses an environmentally-friendly colored transparent solid gum and a preparation method thereof, wherein the environmentally-friendly colored transparent solid gum comprises: 1-5% of a color developing agent, 16-20% of an excipient, 8-28% of deionized water, 26-50% of an adhesive, 41-20% of a humectant, 0.5-1% of a preservative, 0.5-1% of a defoaming agent, 7-10% of a cosolventand 0.1-5% of a pH regulator, wherein the color developing agent is a saturated solution mixed solution of ethyl diacetate and a 55% acetone-alcohol solution. The preparation method comprises: addingdeionized water and an adhesive into a reaction kettle; heating to a temperature of 95 DEG C, stirring for 0.75 h, and cooling to a temperature of 75 DEG C; adding an excipient with a temperature of 75 DEG C and a pH value of 8.3 into the reaction kettle, uniformly mixing and stirring for 1 h, and adjusting the pH value to 8.3; and sequentially adding a color developing agent, a humectant, a preservative, a defoaming agent and a cosolvent into the reaction kettle, and uniformly stirring at a constant temperature of 75 DEG C. Compared with the gum in the prior art, the product of the inventionhas characteristics of added value, transparent and colorful property, attraction, high adhesion, high moisture retention, high adhesion speed and low cost.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environmentally friendly colored transparent solid adhesive and a preparation method thereof. Background technique [0002] Adhesive is a substance used to glue the surfaces of homogeneous or heterogeneous objects together. It can be classified into solid glue and liquid glue according to its form. Solid glue is a kind of animal glue, anticoagulant, fatty acid salt, solvent The solid adhesive made of the main raw materials such as preservatives and preservatives has the advantages of long shelf life, easy to carry, easy to use and firm bonding. [0003] At present, solid glue occupies a major position in office stationery glue because of its characteristics such as easy use and portability, and good bonding performance. However, with the improvement of people's consumption level, consumers have more and more stringent requirements for products, and put forward higher requirements for...
