A kind of waterproof adhesive for loudspeaker assembly and preparation method thereof

Abstract

The invention discloses a waterproof adhesive for loudspeaker assembly, which is composed as follows in parts by weight: 10-15 parts of neoprene rubber; 8-12 parts of SBS; 8-12 parts of SIS; 8-12 parts of tackifying resin; 1-12 parts of plasticizer 2 parts; 0.5-1.5 parts of stabilizer; 0.2-0.8 parts of waterproofing agent; 10-15 parts of filler; 30-50 parts of solvent. The adhesive provided by the invention has good waterproof effect.

Description

technical field [0001] The invention relates to an adhesive, in particular to a waterproof adhesive for loudspeaker assembly and a preparation method thereof. Background technique [0002] Loudspeaker, also known as "horn", is a very commonly used electroacoustic transducer device, which can be seen in electronic and electrical equipment that emits sound. There are many kinds of loudspeakers, which can be divided into electric type (that is, moving coil type), electrostatic type (that is, capacitive type), electromagnetic type (that is, reed type), piezoelectric type (that is, crystal type) and so on. , the latter two are mostly used in rural cable broadcasting networks; according to the frequency range, they can be divided into low-frequency speakers, intermediate-frequency speakers, and high-frequency speakers, which are often used as combined speakers in speakers. The cones of traditional speakers are all made of paper, which can be bonded with ordinary adhesives, but sp...

AI Technical Summary

Problems solved by technology

The cones of traditional speakers are all made of paper, which can be bonded with ordinary adhesives, but speakers like the speakers on the car that require waterproof features are all made of polypropylene plastic cones, which are not suitable for bonding. Adhesives put forward very high requirements, not only to be able to bond plastics such as polypropylene, but also to have waterproof properties. Plastics such as polypropylene, especially after molding, have a smooth surface. Ordinary adhesives can't stick at all
