Benefits of technology

This invention relates to an improved method for producing strong solder on cars' bodies during their production processes. It offers these benefits over existing methods while still being easy to apply with ease compared to current techniques like electroplating or plasma deposition. These improvements make them more efficient than older ways but they have some drawbacks such as poor resistance against corrosive environments and lacked safety features due to its low strength when exposed to water vapor at room temperature.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving upon conventional solvent type brazing glues by providing new types that have better connections between components without causing damage from excess heat during use.

Abstract

The invention provides a preparation method of a welding glue for vehicle manufacturing. The preparation method comprises the following steps: 1) crushing the following raw materials in a formula ratio: epoxy resin, diallyl phthalate, methyl ethyl ketone peroxide, a toughening agent, a viscosity reducer and a plasticizer into powder, and uniformly stirring the substances; 2) adding the uniform powder into a reaction kettle, and then heating the reaction kettle to 120DEG C to obtain a mixed solution in a molten state; 3) adding inert filler into the mixed solution and performing stirring, thenadding polyether amine, calcium silicate hydrate and triglyceride, and performing stirring again to obtain sealant oil-based molten slurry; 4) pouring the sealant oil-based molten slurry into a cooling tower, adding a reinforcing agent, a softening agent and a filling agent, and adjusting the hardness of the welding glue; 5) adding a stabilizer, a moisture absorbent, a pigment and filler, and performing stirring for 15min to form a solid welding glue, and 6) pouring the solid welding glue into a grinding machine, and performing degassing and curing at the end of grinding and dispersing to obtain a welding glue finished product.
