A kind of one-component self-crosslinking benzene-free solvent-based acrylate pressure sensitive adhesive was prepared by free radical polymerization using a self-crosslinking functional monomer N-hydroxymethylacrylamide(NMA).The effects of self-crosslinking monomer content on the peel strength,viscosity,holding power,and conversion rate of pressure sensitive adhesive were systematically studied,and the optimal amount of NMA was selected.The research results showed that when the mass fraction of self-crosslinking monomer NMA added was 0.2%,the peel strength and viscosity of pressure sensitive adhesive met the requirements,and the temperature resistance performance was excellent.The high-temperature holding time at 65℃ increased to 10 h,and the monomer conversion rate was high(up to 95.2%).The prepared pressure sensitive adhesive was coated on the substrate and applied to the carpet protective film.After 30 days,there was no curling phenomenon,and the solvent used was toluene-free,which had the advantages of environmental protection and low toxicity,proving that this product had certain application prospects.
