The epoxy cathodic electrodeposition (CED) coating modified by organic siloxane has been prepared. EP-44 resin was modified by aminosiloxane and organic amine, then to be neutralized with organic acid and emulsified in deionized water with blocked isocyanate as curing agent. The CED films were electrodeposited on tinplate, and the properties of the paint films were investigated. The results indicated that the films shown good performance.

The plywood was prepared using the UF resin modified with isocyanate blocked by sodium bisulfate in this paper. And the effects of the ratio of UF resin and blocked isocyanate, hybrid method and the additive on the properties of the plywood were also studied. The results showed that under the condition of BPI / UF =5%, the order of urea-formaldehyde resin mixed mode curing agent, additive and finally joined the BPI , the bonding strength of the plywood was improved obviously and the formaldehyde release of the plywood could achieve the demand for the national standard.

Composite Molding

In this concept-proof study, a preform-based RTM (Resin Transfer Molding) process is presented that is characterized by first pre-loading the solid curing agent onto the preform, and then injecting the liquid nonreactive resin with an intrinsically low viscosity into the mold to infiltrate and wet the pre-loaded preform. The separation of resin and hardener helped to process inherently high viscosity resins in a convenient way. Rosin-sourced, anhydrite-cured epoxies that would normally be regarded as unsuited to liquid composite molding, were thus processed. Rheological tests revealed that by separating the anhydrite curing agent from a formulated RTM resin system, the remaining epoxy liquid had its flowtime extended. C-scan and glass transition temperature tests showed that the preform pre-loaded with anhydrite was fully infiltrated and wetted by the liquid epoxy, and the two components were diffused and dissolved with each other, and finally, well reacted and cured. Composite laminates made via this approach exhibited roughly comparable quality and mechanical properties with prepreg controls via autoclave or compression molding, respectively. These findings were verified for both carbon and ramie fiber composites.

This paper deals with the feasibility of beach protection project alternative materials - the Yangtze River soil and sand, applies PCSB curing agent to solidify it and to produce beach protection blocks. Experimental studies on the performance of strength, setting time, stability and anti-erosion have been carried out to inquire into the regularity of solidification. Using soil and sand curing blocks instead of concrete blocks in the application of Yangtze River beach protection engineering has advantages of technology, economy and environment protection etc.
