Problems solved by technology

[0002] Glue brushing is an ancient and important unit operation. It usually refers to the process of using heat energy to vaporize the temperature in materials and remove the generated steam. Glue brushing is the most common industrial operation and the most common connection between materials. A common type of operation. At present, glue brushing is a very complicated and insufficiently researched unit operation.
Most of the current glue brushing process adopts the following steps, that is, rough surface treatment of adhesive materials, surface degreasing, glue brushing and drying; and for camera accessories, most camera accessories are composite materials, and the internal parts of these composite materials Small molecules are easy to migrate from the inside of the composite material to the surface of the composite material, which hinders the bonding of the glue and causes bonding failure; after the glue is applied, the glued material will be dried, and such direct drying is easy to make the Oxygen enters the adhesive layer, and the adhesive layer is deformed and the bonding strength between the adhesive and the bonding material is reduced under the condition of reheating, resulting in the destruction of the bond

Embodiment 1

[0020] A glue brushing process for camera accessories, comprising the following steps:

[0021] 1) Wipe the glued parts of the camera accessories and the parts glued to the glued parts of the camera accessories with 96% alcohol for 5 times, then use absorbent paper to wipe off the residual alcohol, and finally use a hair dryer to dry the above parts Air-dry, and control the hot air temperature of the hair dryer to 60°C, and the air-drying time to 170s;

[0022] 2) Grinding the surface of the glued parts of the camera accessories treated in step 1) and the parts glued to the glued parts of the camera accessories with a grinder to roughen the surface to increase its surface energy and increase Bonding area, so as to improve the later adhesive strength;

[0023] 3) Use compressed air to remove debris from the surface of the glued parts of the camera accessories treated in step 2) and the parts glued to the glued parts of the camera accessories, and then put acetone, methyl ethyl...

Abstract

The invention discloses a glue brushing process for a camera accessory, which comprises surface cleaning, surface roughening, surface degreasing, surface oxidation flame processing, surface glue brushing, isolation processing and baking. By improving roughness of a surface of an adhesion material, an infiltration degree of glue solution for the surface of the adhesion material is improved, and a density of contact points between the glue solution and the adhesion material is increased, so that adhesion strength is improved; by carrying out surface degreasing on the adhesion material, a glue failure phenomenon caused by stains on the surface of the adhesion material is avoided; by carrying out oxidation flame processing on the surface of the adhesion material, a layer of isolation membraneis formed on the surface subjected to oxidation flame processing so as to prevent a case that a molecule material inside the adhesion material is migrated to the surface to cause a adhesion failure; and by reasonable squeezing time and isolation processing, damage to adhesion, which is caused by a case that substances such as oxygen and the like in the environment permeate into a glue layer to enable the glue layer to be deformed and reduce adhesion strength between glue and the adhesion material, is prevented.
