Decomposition method for defective metal and rubber bonded pieces and special decomposition liquid thereof

Abstract

The invention discloses a decomposition method for defective metal and rubber bonded pieces and special decomposition liquid thereof. The decomposition method comprises the following steps of: a, selecting a corrosion-resistant container, pouring components of a raw material formula for the decomposition liquid into the container according to weight part, and stirring and mixing to form the decomposition liquid; b, completely immersing the defective bonded pieces in the decomposition liquid; c, adding a cover, and soaking at normal temperature for 10 to 60 hours until metal pieces and rubber are completely swollen, delaminated and separated; d, opening the cover, taking the metal pieces out and putting into a corrosion-resistant basket by using long nose pliers, and simultaneously taking rubber pieces out for abandonment; and e, washing the metal pieces with clear water, and airing the metal pieces. The decomposition I comprises the following raw materials in part by weight: 60 to 100 parts of methylbenzene and 0 to 40 parts of gasoline; and the decomposition liquid II comprises the following raw materials in part by weight: 70 to 90 parts of acetic ether and 10 to 30 parts of n-butyl acetate. The invention has the advantages that: the method is simple; the rubber is removed radically; the metal pieces are not deformed and can be directly recycled without polishing; the loss and production cost of enterprises are reduced; and the environmental and air pollution cannot occur.

Description

technical field [0001] The invention relates to a method for decomposing defective metal and rubber adhesive parts and a special decomposition liquid for the decomposition method. Background technique [0002] As we all know, defective products are unavoidable in the process of producing metal and rubber bonding parts. At present, it is still difficult to completely remove and separate the bonded metal rubber parts to achieve the purpose of metal parts reuse, resulting in great waste. The traditional process method is to use fire to remove it, and then polish and apply glue to the metal parts for reuse. There are three major hazards in this treatment method: ① pollute the surrounding air and cause harm to human health; ② metal parts that have been burned by fire are greatly deformed , Most of them cannot be reused and cause waste, which increases production costs; ③The metal parts burned by fire are easy to change color, and the quality is poor, and they need to be processed...

[0002] As we all know, defective products are unavoidable in the process of producing metal and rubber adhesive parts. At present, it is still difficult to completely remove and separate the bonded metal rubber parts to achieve the purpose of metal parts reuse, resulting in great waste

The traditional process method is to use fire to remove it, and then polish and apply glue to the metal parts for reuse. There are three major hazards in this treatment method: ① pollute the surrounding air and cause harm to human health; ② metal parts that have been burned by fire are greatly deformed , Most of them cannot be reused and cause waste, which increases production costs; ③The metal parts burned by fire are easy to change color, the quality is poor, and they need to be polished and other processes before they can be reused, affecting product quality and wasting human resources
