Abstract

The invention relates to a rubber adhesive and a preparation method and in particular relates to a preparation method of a rubber adhesive RA65. The preparation method comprises: adding white carbon black into a mixing stirrer; starting to stir and dropwise adding hexamethoxy methyl melamine; dropwise adding all the hexamethoxy methyl melamine within 10 minutes to 20 minutes and stirring for 10 minutes to 20 minutes; after standing, stirring for ten minutes again and discharging. According to the preparation method of the rubber adhesive RA65, provided by the invention, materials are added through a dropwise adding manner and are stirred again after standing, so that the stirring is sufficient.

Description

technical field [0001] The invention relates to a rubber adhesive and a preparation method, in particular to a preparation method of the rubber adhesive RA65. Background technique [0002] Adhesive RA-65 Features: Rubber adhesive features: Adhesive RA-65 is a direct adhesive, A, white adhesive system adhesive. It is a methine donor with excellent performance. It is used in conjunction with formaldehyde acceptor RS / RH / RE. It is suitable for bonding various rubbers and various skeleton materials. [0003] The traditional processing method is to directly mix and stir white carbon black and hexamethylolmelamine, resulting in poor stirring effect. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned problems of the prior art and provide a method for preparing a rubber adhesive RA65 with good stirring effect. [0005] The purpose of the present invention is to realize through the following technical solutions: [0006] The ...
