Plastic welding rod

Abstract

The invention discloses a plastic welding rod and aims to solve the problem that a conventional plastic welding rod cannot meet the welding of all plastic products because the components of the plastic welding rod required in the conventional engineering are different from the components of a welded material. The plastic welding rod comprises the following components in percentage by mass: 50 to 90 percent of plastic and 10 to 50 percent of metal powder with a particle size of between 0.1 and 3 millimeters. During preparation, the plastic is heated and added into the metal powder and the mixture is stirred uniformly and molded according to the preparation process of the conventional plastic welding rod to obtain the plastic welding rod. The plastic welding rod can meet the welding requirements of most plastic products and has the advantages of simple manufacturing process, low price, easy popularization and high market value.

Description

technical field

[0001] The invention relates to a welding rod, in particular to a plastic welding rod. Background technique

[0002] With the development of modern industry and agriculture, plastic products are used more and more widely in production and life. In many fields, plastics even have more advantages than steel. However, the biggest disadvantage of plastic products is that once they are broken, leaked, or damaged, it is very difficult to repair them. Many plastic products are no longer useful after damage, but they can be reused by welding and repairing. In engineering, plastic welding rods require that the composition of the material is the same as that of the material to be welded, but because of the diversity of existing plastic product components, other components are often added when manufacturing plastic products, so the existing plastic welding rods, such as polyethylene welding rods , polypropylene welding rods or polyvinyl chloride welding rods often cann...
