Preparation and Application of Blocked & Crosslinked Waterborne Polyurethane Microemulsion as Paper Strengthening Agent Xiao-Juan LAI1,a, Mi-Na GONG1,b and Lei WANG1,c 1 College of chemistry and chemical engineering, Shaanxi University of Science & Technology, Xi’an 710021, China a3578466@163.com, b237214407@qq.com, c05wanglei@sust.edu.cn Keywords: waterborne polyurethane, paper strengthening agent, blocked ratio Abstract.
In this paper, a sery of cationic waterborne polyurethane microemulsions(CBPU) was prepared with isophorone diisocyanate(IPDI), polycaprolactone glycol(PCL), bisphenol A(BPA) as main materials, with imidazole as blocking agent, methyldiethanolamine(MDEA) as cationic hydrophilic chain-extending agent, and N-[(1,1-dimethyl-2-acetyl)ethyl]-β-dihydroxyethylamino propanamide (DDP) as crosslinking agent. the structure of CBPU was characterized by dynamic laser light scattering(DLS) and transmission electron microscopy(TEM).
Exprimental Materials Isophorone diisocyanate(IPDI) and polycaprolactone polyol (PCL, Mn=1000) were obtained from Bayer, Germany.
Conclusions A novel paper strengthening agent was prepared by means of self-emulsifying, with IPDI, PCL, MDEA, DDP, bisphenol A as main materials, with imidazole as blocking agent.

The material grade of model beams are Q235 for steel girders, C30 for concrete slab, and HRB235 for reinforcements.
These test results show that, the transverse slip between the concrete slab and steel girder has certain proportion relationship with the torsion angle of the composite beam, but this conclusion need more experiment support to eliminate the influence of the material Poisson ratio and measure error.
