Embodiment 1

[0013] The preparation process of the solid glue of the present invention is to first soak 12% by weight bone glue with water to fully expand, heat to 80~95°C, stir to dissolve it, and then add 8% by weight white glue and 4% Stir the sugar, keep the temperature for at least 30 minutes, add 16% starch by weight, control the temperature at 65~80℃, keep the temperature for no less than 30 minutes, add 4% by weight emulsifier, 0.02% trimethylolpropane and 2% phthalic anhydride, control the temperature at 40~50℃, keep it cool and solidify at room temperature after keeping it for 20~30 minutes, and finally form the package.

Embodiment 2

[0015] The preparation process of the solid glue of the present invention is to first immerse 14% by weight fish glue in water to fully expand, heat to 80~95°C, stir to dissolve, and then add 9% by weight white glue, 5 % Sugar is stirred, the holding time is not less than 30 minutes, then 20% by weight starch is added, the temperature is controlled at 65~80℃, and the heat preservation is not less than 30 minutes. After stirring, add 5% by weight emulsifier , 0.03% tris 1,4-butanediol and 3% ethylene glycol, control the temperature at 40~50℃, keep it cool and solidify at room temperature after keeping the temperature for 20~30 minutes, and finally form the package.

Embodiment 3

[0017] The preparation process of the solid glue of the present invention is to first soak the bone glue with a weight percentage of 16% in water to fully expand, heat to 80~95°C, stir to dissolve it, and then add 10% white glue and 6% by weight Stir the sugar, keep the temperature for no less than 30 minutes, then add 24% by weight starch, control the temperature at 65~80℃, keep the temperature for no less than 30 minutes, add 6% by weight emulsifier, 0.04% trimethylolpropane and 4% adipic acid, control the temperature at 40~50℃, keep it cool and solidify at room temperature after keeping it warm for 20~30 minutes, and finally form the package.

Abstract

The invention discloses solid glue which is strong in bonding capability and convenient to use. The solid glue comprises the following components by weight: 12-18% of bone glue or fish glue, 8-10% of white glue, 4-6% of sugar, 16-24% of starch, 4-6% of emulsifier, 0.02-0.04% of assistant, 2-4% of polyester and the balance, water. The prepared solid glue greatly improves bonding capability after the assistant and the polyester are introduced, is wide in suitable temperature range, long in use validity period and more convenient to use.

Description

Technical field [0001] The invention relates to a solid glue and a preparation process thereof. Background technique [0002] Solid glue is a new product in adhesives. Its main features are: easy to get raw materials, simple, long shelf life, easy to carry, easy to use, suitable for paper bonding. [0003] However, solid glues on the market generally have problems such as insufficient bonding, narrow temperature range, and short shelf life. Therefore, how to improve the bonding force of solid glues has always been a hot research topic. Summary of the invention [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a solid glue with strong adhesion and convenient use. [0005] In order to achieve the above objectives, the present invention adopts the following technical solutions: [0006] A solid glue containing bone glue or fish glue, white glue, sugar, starch, emulsifier and water. Its composition weight percentage...
