Problems solved by technology

Because this kind of viscose uses oxidized starch as the main raw material, the raw material cost of viscose is reduced, and it is environmentally friendly and non-toxic; it is mixed with hydrogen peroxide, borax, caustic soda, tributyl phosphate and a certain amount of water at room temperature according to a specific process. Not only is the process simple, but the prepared glue can be placed for 12 months without affecting the performance, but the antifreeze performance under low temperature conditions is average

Abstract

The invention discloses a quick-drying adhesive and a preparation method thereof. The quick-drying adhesive consists of the following raw materials in parts by weight: 20 to 60 parts of modified ester cyanopentadienoate, 40 to 70 parts of isononyl isononanoate, 8 to 10 parts of aluminum starch octenylsuccinate, 10 to 20 parts of polypropylsilsesquioxane, 10 to 20 parts of lauroyl lysine, 6 to 10 parts of silane coupling agent, 1 to 8 parts of phenolic compound and 20 to 60 parts of deionized water. The preparation method includes the following steps: the modified ester cyanopentadienoate, the isononyl isononanoate, the aluminum starch octenylsuccinate and the deionized water are mixed and heated to 30 DEG C to 50 DEG C; the silane coupling agent and the phenolic compound are added, reaction takes place under 70 DEG C to 75 DEG C for 5 to 6 minutes, the other components are added and uniformly mixed, reaction takes place under 30 DEG C to 50 DEG C for 20 to 30 minutes, and cooling is carried out. The adhesive disclosed by the invention has good anti-freezing property, can be put under the condition of -30 DEG C for seven days without being frozen, and can be quickly dried and solidified.

Description

technical field [0001] The invention relates to an adhesive, in particular to a quick-drying adhesive and a preparation method thereof. Background technique [0002] A class of organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous materials together and have sufficient strength after curing are collectively referred to as adhesives. [0003] The Chinese patent application with the application number CN201610260202.9 discloses a method for making cellulose viscose from waste paper, which belongs to the field of natural polymers, and specifically includes the following steps: S1 preparation of initial paper cellulose raw materials; S2 preparation of the initial paper cellulose The cellulose raw material is degraded with dilute sulfuric acid; after that, it is filtered, exposed to the sun, aged and ground to obtain a low-polymerization paper cellulose raw material; S3 dissolving the low-polymerization paper c...
