Abstract

The invention discloses a PB composite modified material and a preparation method thereof and a water heater obtained from the PB composite modified material. The PB composite modified material is prepared from the following raw materials in parts by weight: 60-90 parts of PB resin, 5-30 parts of long glass fibers, 5-10 parts of calcined aluminum factory waste and 1-2 parts of processing aid. Theinvention further provides the preparation method of the PB composite modified material and water heater spare parts and the water heater obtained from the PB composite modified material. The long glass fibers and the calcined aluminum factory waste are adopted to modify the PB resin, the performance of the glass fibers is effectively protected from being damaged, the tensile strength of the materials is improved, the shrinkage deformation of the materials is reduced, the problem of pressure deformation of hot water system parts is solved, meanwhile, the flatness of the surfaces of the parts is improved, internal shrinkage holes of the parts are reduced, the compactness of the parts is improved, the strength of the parts is improved, and the sealing performance of connecting parts in a hotwater system is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of water heaters, in particular to a PB composite modified material, a preparation method thereof and a water heater obtained therefrom. Background technique [0002] Polybutene (PB) is an inert polymer, known as "gold in plastics" because of its excellent physical and chemical properties; it has excellent temperature resistance, durability, chemical stability and plasticity, odorless, Odorless and non-toxic, it is one of the most advanced chemical materials in the world. Products such as pipes made of PB have excellent thermal creep resistance, can be used for a long time at 95°C, and have a maximum service temperature of 110°C. They have good environmental stress crack resistance and good heat preservation effect, which is 1 / 1700 of copper. It can be welded and does not bond with concrete and scale. At the same time, it also has the advantages of light weight, good flexibility and good impact resistance. ...
