Problems solved by technology

The disadvantage of natural polymer adhesives is low strength, and the disadvantage of synthetic polymer adhesives is that the production process is complicated and the cost is high. Polymer adhesives can be used for leather, wood, fabrics, etc. The current polymer adhesives have no insect-proof function.

Embodiment 1

[0014] A preparation method of a composite polymer adhesive containing clove extract is as follows:

[0015] Soak cloves in 70% ethanol at a temperature of 45°C for 30 minutes. The ratio of cloves to ethanol is 1:10 (g / ml) to obtain an ethanol extract of cloves; 3000g bone glue, 2000g polystyrene Add 3500g of ethanol extract of cloves and stir for 1 hour at 50°C; add 100g of curing agent m-phenylenediamine and 200g of tackifier rosin resin, and stir for 1 hour at 40°C.

Embodiment 2

[0017] A preparation method of a composite polymer adhesive containing clove extract is as follows:

[0018] Add cloves to 70% ethanol for soaking, the soaking temperature is 50°C, soak for 45 minutes, the dosage ratio of cloves and ethanol is 1:12 (g / ml), to obtain the ethanol extract of cloves; 3500g bone glue, 2500g polystyrene Add 4000g of clove ethanol extract, stir at 55°C for 1.5 hours; add 150g of curing agent m-phenylenediamine, 250g of tackifier rosin resin, and stir at 45°C for 1.5 hours.

Embodiment 3

[0020] A preparation method of a composite polymer adhesive containing clove extract is as follows:

[0021] Soak cloves in 70% ethanol at a temperature of 55°C for 60 minutes. The ratio of cloves to ethanol is 1:15 (g / ml) to obtain ethanol extract of cloves; mix 4000g bone glue, 3000g polystyrene Add 4500g of clove ethanol extract and stir for 2 hours at 60°C; add 200g of curing agent m-phenylenediamine and 300g of tackifier rosin resin, and stir for 2 hours at 50°C.

[0022] Through experiments, the composite polymer adhesive containing clove extract of the present invention reduces cost by 10%-13% compared with ordinary polymer adhesives, increases strength by 12%-15%, and has the function of preventing insects.

Abstract

The invention provides a composite polymer adhesive containing clove extract, the composite polymer adhesive is prepared from the following raw materials by weight: 30-40 parts of bone glue, 20-30 parts of polystyrene, 1-2 parts of a curing agent, 2-3 parts of a tackifier and 35-45 parts of the clove extract. The composite polymer adhesive containing the clove extract combines the advantages of natural polymer adhesives and synthetic polymer adhesives, has the advantages of high strength, simple manufacturing process and low cost, a contained clove component is insect-proof, and the compositepolymer adhesive is especially suitable for leather, wood, fabrics, and the like.

Description

technical field [0001] The invention belongs to the field of polymers, in particular to a composite polymer adhesive containing clove extract. Background technique [0002] Polymer adhesives are a type of adhesive material based on polymer compounds, also known as polymer adhesives or polymer binders, such as paste, swim bladder glue, epoxy glue, etc. Adhesive materials mainly made of natural or synthetic polymer compounds. According to its source, it can be divided into natural polymer adhesives and synthetic polymer adhesives. Natural polymer adhesives are made of natural animal and plant adhesive substances, such as hide glue, bone glue, starch glue, protein glue, resin glue, natural rubber pulp, etc. The feature is that it can make full use of natural resources, such as lignin, a by-product of papermaking, cellulose from waste wood and herbaceous plants, and marine biological resources. It is cheap, non-toxic or low-toxic, and easy to process, but it is not resistant ...
