Abstract
The invention discloses a preparation method of multi-functional liquid glue. The preparation method comprises: adding 5 parts by weight of deionized water and 10 to 15 parts by weight of polyvinyl alcohol into a reaction vessel under room temperature; heating the materials to a temperature of 90 DEG C; after the materials are completely dissolved, adding 20 to 25 parts by weight of butyl acetate and 15 to 20 parts by weight of glycerin; leaving the materials to react for 1 hour with preserved temperature; cooling the materials to room temperature; adding 8 to 15 parts by weight of ethanol,15 to 20 parts by weight of polyvinyl acetate, a proper amount of an antiseptic agent and a proper amount of an antifoaming agent; leaving the material to de-foam by standing. The technology of the invention is simple. Once the component proportions, the temperatures, and the reaction times are controlled accurately, the preparation can be successful. During the whole process, no wasting is caused, and no pollution is generated. The production process remains in a clean condition. The produced liquid glue is a single-component liquid glue which is easy to use and is multi-purposed. The liquid glue has strong viscosity and can be widely applied for gluing papers, card boards, fabrics, cork, leather, wood materials, ceramics, colored glaze, cards, plastics, and the like.
Description
technical field [0001] The invention relates to a preparation method of multifunctional liquid glue. Background technique [0002] Liquid glue has good viscosity and can be used to paste paper products. It is a high-quality office and school supplies. [0003] However, the commonly used liquid glue is only used to paste paper, and when other materials need to be pasted, more glues such as 502 glue and Baide glue are used. [0004] 502 glue is a one-component instant curing adhesive synthesized by advanced production technology, mainly based on α-ethyl cyanoacrylate, adding tackifier, stabilizer, toughening agent, polymerization inhibitor, etc. [0005] 502 glue is a kind of strong glue, colorless and transparent, good fluidity, easy to volatilize, and polymerize and solidify when it meets water. And 502 glue is one-component, fast curing, easy to use, strong adhesion, wide range of bonding materials, can be used for steel, non-ferrous metals, rubber, leather, plastics, cer...
