Abstract

The invention discloses environment-friendly low-temperature curing PVC plastisol and a preparation method thereof. The environment-friendly low-temperature curing PVC plastisol uses PVC paste resin, chloride vinyl acetate copolymerized paste resin, a plasticizer, a heat stabilizer, an adhesion promoter, BPU-Si, filler, a thixotropic agent, CaO, a viscosity reducer and the like as raw materials. The tensile strength of the prepared PVC plastisol can be up to 6-8 MPa, and the elongation at break can be up to 210%-270%. The adopted plasticizer is the novel environment-friendly plasticizer and has the advantages of being biodegradable, low in volatility, high in plastifying effect and the like. Under the synergistic effect of end-capped polyurethane and an adhesion promoter, the plastifying temperature (120-130 DEG C) of the plastisol can be effectively reduced, and the mechanical properties, elasticity and adhesion of the PVC plastisol are remarkably improved.

Description

technical field

[0001] The invention relates to an environment-friendly low-temperature curing PVC plastisol and a preparation method thereof. Background technique

[0002] PVC plastisols are widely used in some important commercial products, such as safety floors in the automotive industry, corrosion and stone chip coatings, synthetic leather products and sealants for instrument panels; vinyl-coated wallpapers and fabric exterior coatings tarpaulins and advertising banners; stadium roofs.

[0003] At present, the preparation of PVC plastisol mostly uses traditional ortho-phthalic plasticizers. Ophthalmic plasticizers can cause cancer due to the benzene ring in their structure, and have toxicity problems. At the same time, the mechanical properties of PVC plastisol products are generally not high. Generally, the tensile strength is only 2-3MPa, and the elongation at break is only 160%- 210%, which limits its application in the field of commercial products. The curing temp...
