Embodiment 1

[0035] Put 1,000 grams of asphalt and 15 liters of n-heptane into an industrial 30-liter reactor, heat up to 130°C, and treat at this temperature for 8 hours. The obtained product is filtered on an industrial filter cloth to obtain brown of the filtrate.

[0036] All the filtrates were introduced into a liquid dryer, and then dried at 120° C. for 5 hours by feeding 50 liters / hour of nitrogen gas to obtain a black blocky solid.

[0037] The massive solid was pulverized in a pulverizer and then put into a pulverizer for pulverization treatment. The treatment time was 12 minutes to obtain black particles.

[0038] After passing the black particles through a 100-mesh sieve, take 300 grams and 2000 grams of ethyl α-cyanoacrylate, 30 grams of urethane diol, 30 grams of 2,4,4-trimethyl-1,6-hexane Diamine, 30 grams of ethylene carbonate, 30 grams of dichlorohexamethylene diisocyanate, 30 grams of melamine formaldehyde resin, 30 grams of E-44 epoxy resin, 30 grams of vinyl chloride re...

[0040] Put 1,000 grams of asphalt and 8 liters of n-heptane into an industrial 30-liter reaction kettle, heat up to 100°C, and treat at this temperature for 10 hours. The obtained product is filtered on an industrial filter cloth to obtain brown of the filtrate.

[0041] All the filtrates were introduced into a liquid dryer, and then dried at 120° C. for 5 hours by feeding 50 liters / hour of nitrogen gas to obtain a black blocky solid.

[0042] The massive solid was pulverized in a pulverizer and then put into a pulverizer for pulverization treatment. The treatment time was 12 minutes to obtain black particles.

[0043] After passing the black particles through a 100-mesh sieve, take 300 grams and 1500 grams of ethyl α-cyanoacrylate, 30 grams of urethane diol, 30 grams of 2,4,4-trimethyl-1,6-hexane Diamine, 30 grams of ethylene carbonate, 30 grams of dichlorohexamethylene diisocyanate, 30 grams of melamine formaldehyde resin, 30 grams of E-44 epoxy resin, 30 grams of vinyl chl...

Embodiment 3

[0045] Put 1,000 grams of asphalt and 12 liters of n-heptane into an industrial 30-liter reaction kettle, heat up to 150°C, and treat at this temperature for 1 hour, and filter the obtained product on an industrial filter cloth to obtain brown of the filtrate.

[0046] All the filtrates were introduced into a liquid dryer, and then dried at 120° C. for 5 hours by feeding 50 liters / hour of nitrogen gas to obtain a black blocky solid.

[0047] The massive solid was pulverized in a pulverizer and then put into a pulverizer for pulverization treatment. The treatment time was 12 minutes to obtain black particles.

[0048] After passing the black particles through a 100-mesh sieve, take 300 grams and 4500 grams of ethyl α-cyanoacrylate, 30 grams of urethane diol, 30 grams of 2,4,4-trimethyl-1,6-hexane Diamine, 30 grams of ethylene carbonate, 30 grams of dichlorohexamethylene diisocyanate, 30 grams of melamine formaldehyde resin, 30 grams of E-44 epoxy resin, 30 grams of vinyl chlor...

Abstract

The invention discloses a plastic adhesive. The adhesive is prepared in steps as follows: a, asphalt and n-heptane are mixed, treated in an airtight reaction kettle at the temperature of 100-150 DEG C for 1-12 h and filtered, and filtrate is obtained; b, the filtrate is dried in the nitrogen fluid state at the temperature of 100-150 DEG C for 1-10 h, solids are obtained, finely ground, sieved by a 50-120-mesh sieve and then dispersed in ethyl alpha cyanoacrylate to be stirred for 10-30 min, ethyl carbamate glycol, 2,4,4-trimethyl-1,6-hexamethylene diamine, ethylene carbonate, dichloro-hexylidene diisocyanate, melamino-formaldehyde resin, epoxy resin, vinyl chloride-vinyl acetate resin, an expanding agent, desulfurized gypsum and a curing agent are added, and the plastic adhesive is obtained. The provided plastic adhesive can powerfully bond a wood material and plastic, and no harmful organic substances are produced.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a plastic adhesive. Background technique [0002] Adhesives are organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous parts (or materials) together and have sufficient strength after curing. [0003] Chinese patent CN1664042A discloses a modified waste polystyrene foam adhesive, which is to mix the cyclohexene solution of waste polystyrene foam with the ethyl acetate solution of SBS, and fully stir them evenly. Add rosin, stir until completely dissolved, add emulsifier sodium dodecylbenzenesulfonate and OP-10 in proportion, mix and stir evenly; then plasticizer dibutyl phthalate in proportion, mix and stir evenly, That is the adhesive. Since the raw material is waste polystyrene foam, the cyclohexene used is a low-toxic, cheap industrial-grade solvent. The raw material has a wide range of sources and a simp...
