The environment-friendly adhesive comprises raw materials, wherein the raw materials comprise pigments.
According to the environment-friendly adhesive provided by the embodiment of the invention, the addition amount of the pigment is 1-2 parts by weight.
The preparation method of the environment-friendly adhesive comprises the following steps:
(1) Respectively weighing the PVC paste resin and the environment-friendly plasticizer according to the weight ratio, and uniformly mixing to form a mixture for later use;
(2) And (2) adding a stabilizer into the mixture obtained in the step (1), stirring, uniformly mixing, then adding a viscosity reducer to adjust the viscosity, adding other raw materials, and uniformly mixing to obtain milky gel, thus obtaining the environment-friendly adhesive.
According to the preparation method of the environment-friendly adhesive, in the step (1), the pvc paste resin and the environment-friendly plasticizer are stirred for 15 minutes and uniformly mixed to form a mixing agent.
According to the preparation method of the environment-friendly adhesive, in the step (2), the stabilizer is added and stirred for 5 minutes, and the mixture is uniformly mixed.
According to the preparation method of the environment-friendly adhesive, the viscosity of the environment-friendly adhesive is adjusted to 2400-2600 Pa-s by adding the viscosity reducer in the step (2).
According to the preparation method of the environment-friendly adhesive, the viscosity is 2500Pa · s.
The PVC paste resin is produced by vinyl chloride-vinyl acetate copolymer resin by adopting a micro-suspension copolymerization process technology, and because vinyl acetate is introduced into a PVC molecular rigid chain, PVC intermolecular weakening is realized, and intermolecular lunar calendar is reduced, so that compared with homopolymerization PVC paste resin, the gelation temperature and the melting temperature are obviously reduced (30-40 ℃). In addition, due to the introduction of ester groups, the dissolution speed of the resin and the plasticizer is improved, and the adhesive force of the resin and various adhesive base materials is enhanced. As an important material for reducing the processing temperature, increasing the plasticizing temperature and improving the product performance, the thermoplastic resin is widely applied to the industries of PVC automobile plastisols (including chassis stone-impact-resistant coating, vehicle body welding seam sealant spot welding glue, filter core glue, buffer glue and the like), PVC carpet tile backing adhesives, printing ink, thermosensitive fabric coatings, chemical foaming products and the like, and can replace similar products abroad. The PVC paste resin has the particle size of 1-5 mu m, low viscosity and good storage performance.
The DPHP environment-friendly plasticizer is basically colorless, transparent liquid, high in stability and soluble in most organic solvents, has good compatibility with pvc paste resin, has the plasticizing efficiency equivalent to that of DINP, has smaller specific gravity than DINP, and is superior to DIDP. The electrical insulation performance is the same as DIDP, but the volatility is smaller, the temperature can be higher, the safety is highest, the volatility in soft ethylene is lower, and the electrical insulation material can be applied to automobiles, wires and cables. Acid value is below 0.05mgKOH/g, refractive index (25 ℃) is 1.484+0.005; the water content is less than 0.05wt%, and the heating loss is less than 0.10 wt%.
