The future development of phenolic resin

Related to the development of phenolic resin and research work, mainly around the enhancement, flame retardant, low smoke, applicability and molding line to develop functional and intensification, scientists from all over the world of high value-added phenolic resin material as the object of research and development. Does not contain the formaldehyde and environmentally friendly new phenolic resin.

New phenolic resin (xylok) for polymer compound, is made up of phenols and aromatic alkyl ether by condensation reaction, new phenolic resin with good mechanical properties, heat resistance, widely used in diamond products, grinding wheel manufacturing and other industries. New phenolic resin adhesive power is strong, good chemical stability, high heat resistance, the hardening shrink, dimension stability. Bond strength by more than 20% higher than that of phenolic resin, heat resistance increased by more than 100 ℃. New phenolic resin can be use for a long time under 250 ℃, products wet alkali resistance. New phenolic resin as bond diamond grinding wheel, using the method is: the new phenolic resin and phenolic resin according to 1:3 mixed use, not only improve the strength of phenolic resin, also improves the heat resistance and grinding ratio. Such as using the new phenolic resin alone, the life of the grinding wheel is 8 times, phenolic resin in the production process is about 30% higher than the intensity of phenolic resin, grinding effect is improved.

It compared with other synthetic resin buttons, has the following features:

1. Good temperature resistance Ordinary resin buttons can only around 100 ℃ hot water to boil, urine aldehyde resin buttons can reach 120 ℃ or so. As for iron ironing temperature can be higher for a short period of time.

2. High hardness, good wear-resisting strokes Compared with resin buttons, hardness higher urine aldehyde resin buttons, it is also a kind of thermosetting crosslinking type plastic, so the wear resistance is very good, not easy to damage, so this kind of button can be used for washing often suits, shirts and other clothing.

3. Good resistance to organic solvents It is more than the unsaturated resin buttons has superior organic solution resistance, therefore, can from the erosion and does not destroy the dry cleaner.
