A kind of phenolic resin of modified by cardanol and the preparation method of phenolaldehyde moulding compound

The present invention relates to Polymer Synthesizing and technical field of modification, the phenolic resin of specifically a kind of modified by cardanol and the preparation method of phenolaldehyde moulding compound, the preparation method of the phenolic resin of the modified by cardanol comprise the following steps：1) anacardol and formaldehyde are reacted into the methylolated anacardol of generation in the basic conditions, component A is obtained after dehydration；2) phenol is reacted in acid condition with formaldehyde, B component is obtained after dehydration；3) component A and acidic catalyst are added into B component, dehydration obtains Cardanol Modified PF Resin after reaction.The beneficial effects of the present invention are：The phenolic resin of the modified by cardanol prepared using the inventive method, can prepare that toughness is preferable, the more preferable phenolaldehyde moulding compound of heat resistance under same process conditions；The phenolaldehyde moulding compound prepared using the inventive method, compared to existing phenolaldehyde moulding compound, mechanical performance is more excellent, and heat resistance is more preferable, and with good cost advantage.
