CN105017979A - Application method of adhesive - Google Patents

Abstract

The invention provides an application method of an adhesive. The method is characterized in that the adhesive coats the surfaces of an aluminium plate and a nylon material to bond the aluminium plate and the nylon material, the bonding temperature is 22-28 DEG C, and bonding time is 12 hours or above.

Description

A kind of adhesive application method

technical field

The invention relates to the field of composite material processing. the

Background technique

The inner surface of the EC175-Z15 tail beam is bonded to the 2024 aluminum plate on the inner surface with wire clips, and the glue used is ECS6011. Because ECS6011 is purchased abroad, the order quantity is small, and it is often out of stock. Need to use another adhesive instead. Need to ensure the requirements of adhesive performance. the

EC2216 adhesives were previously only used for metal-to-metal bonding. the

Contents of the invention

The technical problem to be solved in the present invention:

The wire clips used on the inner surface of the tail boom are made of nylon (polyamide resin), and after being bonded to the aluminum plate, they can be placed at room temperature for 24 hours to reach a maximum strength of 15MPa. Its function is to block the wire passing through the slot. According to the principle of using EC175-Z15 materials, it is necessary to choose other grades of adhesives used in EC175-Z15 to replace them. Adhesives that cure at room temperature and have a strength of more than 15MPa should be selected. the

Technical scheme of the present invention:

An application method of EC2216 adhesive, characterized in that the EC2216 adhesive is coated on the surface of aluminum plate and nylon material, and the aluminum plate and nylon material are bonded, the bonding temperature is 22°C-28°C, and the bonding time is more than 12 hours. the

Beneficial effects of the present invention:

After test and analysis, ECS6011 can be replaced by EC2216 glue, its strength and construction can fully meet the bonding requirements, which solves the impact on production caused by the failure of ECS6011 glue to be supplied in time. the

Detailed ways

The present invention will be specifically described below. The application method of the EC2216 adhesive is to apply the EC2216 adhesive between the aluminum plate and the nylon material, and then bond the aluminum plate and the nylon material. The bonding temperature is 22°C-28°C, and the bonding time is more than 12 hours. the

By using EC2216 to bond three groups of wire clips (nylon) and aluminum plate test pieces and test them, the shear strength indexes are 17.3, 17.6 and 17.7 respectively, the strength meets the requirements, and it can replace ECS6011 adhesive for machine use. the
