Modification and material control of different building adhesives based on cost factors
Based on the design and application requirements of cost control for building adhesives,this paper took traditional cyanate adhesive as the research object,and investigated its influence on the thermal stability and bond-ing properties of building adhesives by adding phenol,hydroquinone,resorcinol and resorcinol to the adhesives,and analyzed the application of building adhesives based on cost control.The results showed that no matter before or af-ter modification of phenol,hydroquinone,resorcinol and resorcinol,there was little difference in the positions of the characteristic peaks in the IR spectra of the adhesive,and there were all the characteristic peaks of—OH absorp-tion,—CH3,—OCN,C===N and Cr0.After adding phenol,hydroquinone,resorcinol and resorcinol to the adhesive,the thermal stability of the adhesive sample increased to different degrees,and the coke yield increased slightly,which indicated that the modified adhesive could ensure the good thermal stability of the cyanate adhesive.After adding phenol,hydroquinone,resorcinol and resorcinol to the adhesive,the shear strength of the adhesive samples increased to different degrees.The suitable modifier for construction glue based on cost control is 1% hydroquinone.
