谈谈压敏胶粘带初粘性的测试

胶粘剂的初粘性，尤其是压敏胶粘带的初粘性能，对压敏胶粘带的实用性能关系颇大。用现行国标为代表的斜面滚球法测试压敏胶粘带的初粘性，可以对胶粘带生产的质量控制起到很好的作用，但用它直接探索胶粘剂的初粘性是有缺陷的。本文分析了其中的原因，介绍了几种国外新的压敏胶粘带初粘性测试仪器，并提出了对初粘性国标将来修订时的改进建议。

Fast advancement and hardening acceleration of low condensation alkaline phenol‐formaldehyde resins by esters and copolymerized urea. II. Esters during resin reaction and effect of guanidine salts

Guanidine carbonate is shown to be an accelerator of phenol‐formaldehyde (PF) resins that while yielding slightly slower gel times than triacetin when added to a PF resin glue mix, is also capable of giving glue‐mix pot lives on the order of several days. Hence, this is long enough to be premixed with the resin long before use. Both triacetin and guanidine carbonate used as simple glue‐mix additives are shown to increase the ultimate strength of the resin bond, whatever the length of the curing time used for the purpose. This is shown by thermomechanical analysis and the application to wood particleboard. Triacetin is shown to be usable during PF resin preparation rather than just being added to the glue mix, yielding better resins capable of giving higher bond values without a great acceleration of the geling of the resin itself. The mechanisms involved in the acceleration of PF resins introduced by both compounds appears to be based on facilitating reactions of crosslinking involving carbonic acid ions present in the resin solution. © 2000 John Wiley & Sons, Inc.

Highly dispersed melamine cyanurate flame‐retardant epoxy resin composites

Ultrafine dispersion of flame retardants in polymer matrices favors improving the performance of flame‐retardant polymers, but is still a challenge on most occasions. In the present research, an efficient method was employed to realize satisfactory dispersion of a nitrogen flame retardant, melamine cyanurate (MCA), in epoxy resin (EP) composites, and meanwhile integrated the synthesis of MCA with the preparation of the flame‐retardant composites. In the conventional technology, EP pre‐polymer glue with added MCA powder (synthesized in water, then dried and pulverized) is used to coat glass fabrics, which are compressed into laminated boards. Here, MCA was synthesized in a good solvent for EP, and then EP pre‐polymer was directly dissolved in the MCA suspension to obtain the in situ synthesized flame‐retardant glue. In this way, MCA could keep perfect dispersion whether in the glue or cured resin. Compared with the conventional addition system easily resulting in the aggregation of MCA particles, the in situ synthesized MCA flame‐retardant system exhibited much better stability of the coating glue, and markedly improved flame retardancy and mechanical properties. © 2016 Society of Chemical Industry     

Improved Water Resistance and Adhesive Performance of a Commercial UF Resin Blended with Glutaraldehyde

The influence of glutaraldehyde blend on the properties of a commercially available resin in moist conditions was investigated. A UF resin with very low water resistance was blended with glutaraldehyde prior to the thermosetting step and the adhesive performance of the modified adhesive systems was studied. Experiments were performed on birch two-layer co-oriented plywood. It was shown that blending a commercial glue-mix as sold with glutaraldehyde can be an effective way to improve water resistance of the glue without introducing additional -NH₂ moiety. It was also found that glutaraldehyde does not deteriorate properties of the glue in the dry state, while glue susceptibility to boiling water is markedly reduced.
