[0028] The present invention also provides an embodiment of the method for preparing the above-mentioned friction sheet, the method includes the following steps:
[0029] Resin compound A is prepared by mixing the following parts by weight: 100 parts of vinyl ester resin solution diluted with styrene and having a solid content of 65% to 70%, 2 to 4 parts of crosslinking reaction initiator and 1-2 parts of cross-linking reaction activator;
[0030] Put the following components by weight into a kneader and knead into a dough-like material: 35-44 parts of resin compound A, 3-6 parts of cardanol-modified phenalkamine, 3-6 parts of carboxyl-terminated liquid rubber, 10-15 parts of friction modifier, 15 parts of reinforcing fiber material, 10-12 parts of white carbon black, 15-20 parts of magnesium hydroxide;
[0031] Put the friction plate liner into the lower mold of the mold, put the dough on the friction plate liner, coat the emulsified paraffin type release agent on the inner ...
Embodiment 1
[0036] A friction plate material, made of the following components by weight: 35 parts of resin compound A, 5 parts of cardanol modified phenalkamine, 5 parts of carboxyl-terminated liquid rubber, 15 parts of friction performance regulator, 15 parts Parts of reinforced fiber material, 10 parts of white carbon black, 15 parts of magnesium hydroxide.
[0037]Wherein: resin compound A is made up of each component of following parts by weight: 100 parts are diluted by styrene and solid content is the vinyl ester resin solution of 65%, 2 parts of cross-linking reaction initiator and 1 part of cross-linking Reaction activator. The solid vinyl ester resin is obtained by mixing acrylic vinyl resin and methacrylic acid fumaric acid vinyl resin in a ratio of 1:1 by weight; the crosslinking reaction initiator is phthalic acid of 50% methyl ethyl ketone peroxide Dimethyl ester solution; the cross-linking reaction activator is 50% cobalt naphthenate solution in dimethyl phthalate.
