Embodiment 1

[0015] A kind of transparent solid glue provided by the present invention, comprises the polyvinylpyrrolidone of 11% as adhesive, the glycerin of 4% as moisturizing agent, the sodium stearate of 5% as gelling agent, the activator is 4% of clear soap base, The defoaming agent is 1.2% organic silicon, the preservative is a mixture of 0.2% propyl ester and ethyl ester in equal proportions, the pH adjusting agent is 0.6% sodium hydroxide, and the water is 74%. The above components are calculated by weight percentage.

[0016] This example also provides a method for preparing a transparent solid glue. First, add 74% water to the reaction kettle, add 11% polyvinylpyrrolidone while heating and stir, and slowly raise the temperature to 85-90°C. Polyvinylpyrrolidone After dissolving, add 5% sodium stearate, 4% glycerin, 4% soap base, 1.2% organic silicon, and then add 0.6% sodium hydroxide to adjust the pH value of the material to 9 to 14. After stirring at a constant temperature Add 0...

Embodiment 2

[0018] A kind of transparent solid glue provided by the present invention, comprising adhesive is 6% polyvinylpyrrolidone and 6% polyvinyl alcohol, humectant is 5% sorbitol, gelling agent is 10% calcium stearate, active agent is 4.5% soap base, 0.6% silicone defoamer, 0.4% propyl ester and ethyl ester equal ratio preservative, 0.5% sodium hydroxide as PH adjustment agent, 67% water, the above groups Points are calculated by weight percentage.

[0019] This embodiment also provides a preparation method for transparent solid glue. First, add 67% water to the reaction kettle, add 16% polyvinylpyrrolidone and 6% polyvinyl alcohol while heating and stir, and slowly heat up to 85- 90°C, after dissolving polyvinylpyrrolidone, add 10% calcium stearate, 5% sorbitol, 4.5% soap base, 0.6% organic silicon, and then add 0.6% sodium hydroxide to adjust the pH value of the material to 9 To 14, stir evenly at constant temperature, add 0.4% mixture of propyl ester and ethyl ester in equal pro...

Embodiment 3

[0021] The same effect of the present invention can also be achieved by replacing the adhesive in any one of Examples 1 to 2 with polyacrylate emulsion.

Abstract

The invention provides a transparent solid adhesive which comprises the following components in percentage by weight: 4-50% of an adhesive, 1-20% of a humectant, 2-20% of gel, 3-6% of an active agent, 0.5-2% of a defoaming agent, 0.1-1% of a preservative, 0.1-3% of PH adjusting agent and 20-75% of water. Compared with the prior art, the transparent solid adhesive has the beneficial effects that the solid adhesive is transparent in color, high in hardness, good in moisture retention, smooth without reside dropping when being coated, good in oxidation resistance and environment-friendly and non-toxic.

Description

technical field [0001] The invention relates to the field of office supplies, in particular to a transparent solid glue and a preparation method thereof. Background technique [0002] Most of the solid glue stick products on the existing market use modified polyvinyl alcohol, polyvinylpyrrolidone, etc. as adhesives, and add modifiers and excipients to prepare. Solid glue sticks are mostly white or yellow-white, and there are also some colored solid glue sticks made by adding pigments or pigments, but they are not as good as transparent solid glue, and transparent glue looks and uses cleaner , more environmentally friendly. Therefore, need to invent a kind of environment-friendly transparent solid glue, satisfy the use demand of consumer. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a transparent solid glue, comprising 4% to 50% of adhesive, 1% to 20% of moisturizing agent, 2% to 20% of gelling agent, 3...
