A low-odor，low-temperature plasticized polyvinyl chloride chip-resistant coatings was prepared. The effects of plasticizer，paste resin and adhesion promoter on sample odor，bending and adhesion were studied. The results showed that diisononyl terephthalate andphenyl alkyl sulfonate were used as the mixed plasticizers，which could reduce the odor and meet the requirements of flexibility after low temperature plasticization. Siamvic 370HD pasteresin provided good viscosity stability，and used as the main resin to improve the flow of coatings；PA1384 copolymer resin from Arkema was used as auxiliary resin，and the spray width was less affected，which could improve the tensile strength of the coatings after lowtemperature plasticization. N382 adhesion promoter showed not only lower odor，but also better adhesion after low temperature plasticization.
