A kind of production equipment and technological process of hexamethylolmelamine

Abstract

The invention discloses a hexamethylol melamine production device and a technology process, and aims to improve the existing shortcoming that heath of workers can be damaged in production as formaldehyde serving as a raw material for producing hexamethylol melamine has volatility. According to the production device, product quality is good and stable than that of an original process, and yield is improved by a mechanized assembly line method. Products can be produced in a sealing environment by the assembly line method, the viscosity of the products after reaction and curing of rubber adhesives is high, so that the products cannot be conveyed by the aid of a common conveying device, a conveying section of the device is provided with a curing, cooling and conveying integrated machine, the curing, cooling and conveying integrated machine comprises a curing tank, a cooling cabin and a 16-shaft screw conveying device, and formaldehyde volatilization can be effectively prevented.

Description

technical field [0001] The invention relates to the field of polymer production technology, in particular to a production equipment and process flow of hexamethylolmelamine. Background technique [0002] Hexamethylolmelamine, also known as 2,4,6-three (N,N-dimethylolamino)-1,3,5-triazine (C3N6(CH2OH)6), is mainly used in architectural coatings, automotive Adhesive raw materials, suitable for the production of high-performance adhesive A, intermediates of adhesive RA, paint additives, clothing finishing agents, high-performance composite materials and the processing of downstream fine chemical products. [0003] Hexamethylolmelamine is the raw material for rubber adhesives and amino resins. It is polymerized by addition reaction of formaldehyde and melamine as the main raw materials. The reaction is an exothermic reaction. When the temperature rises in a closed container It will polymerize and solidify immediately, and it cannot be taken out of the container. Moreover, form...

Problems solved by technology

Moreover, formaldehyde, one of the raw materials, is easy to leak, and the working environment is seriously polluted. Workers must wear gas masks to work, which affects the physical and mental health of workers.

[0004] The traditional production of hexamethylol melamine is carried out through the distribution of curing machine and cooling machine conveyor. This method can easily cause formaldehyde and melamine to solidify in a closed container and cannot be taken out, which affects its work efficiency, and the product is a rubber adhesive reaction. In solidification production, the overall viscosity after solidification is high, which cannot be transported by ordinary conveying equipment, and the well-reacted materials in traditional production are put into the solidification tank, and after solidification, the materials are manually dug out of the tank from the tank and naturally cooled on the ground , and then manually shoveled to the conveyor belt and sent to the dryer for drying, and finally the finished product is packaged, which is very troublesome to operate manually
