Problems solved by technology

[0002] Amino molding compound (commonly known as electric jade powder) plays a very important role in the field of chemical materials, especially the production process of forming electric jade powder into granules is very important. The process of electric jade powder granulation mainly includes kneading, drying, cooling , crushing and packaging. At present, the kneading process of domestic electric jade powder granulation is mainly made of urea, formaldehyde, wood pulp, titanium dioxide and other raw materials through the kneading reaction of the reaction pot. The process of this kind of product is complicated and requires steam and reaction pot. The physical properties are unstable, there are many chemical volatiles, the fluidity is variable, and the shelf life is about 3-6 months; therefore, the lack of easy flow performance and strength of electric jade powder granulation urgently needs to be improved. A new electric jade powder granulation Technology, especially a new type of kneading technology urgently needs to appear

Embodiment 1

[0027] Example 1. The compound curing agent added in the kneading process of the present invention is a combination of curing agent D and ammonium chloride, the content ratio of curing agent D to ammonium chloride is 1.5, and the added insulation enhancer is rubber powder For the mixture with alkaline short fiber, the content ratio of rubber powder and alkaline short fiber is 0.8, the kneading temperature of the screw extruder is controlled at 80℃-115℃, and the kneading temperature of the roll mill is controlled at 45℃-70℃. The time is 1.5h, the kneaded product is dried in the drying process, and the drying temperature is controlled to be 90°C-100°C and the water content is about 4%.

Embodiment 2

[0028] In Example 2, the compound curing agent added in the kneading process of the present invention is a composition of phthalic acid and ammonium chloride, the content ratio of phthalic acid to ammonium chloride is 1.5, and the added insulation enhancer is The mixture of silicon powder and alkaline short fiber, the content ratio of silicon powder and alkaline short fiber is 0.8, the kneading temperature of the screw extruder is controlled at 80℃-115℃, and the kneading temperature of the roll mill is controlled at 45℃-70℃ , The kneading time is 1.5h, the kneading product is dried in the drying process, the drying temperature is controlled to be 90℃-100℃, and the water content is about 4%.

Abstract

Prilling process of an amino molding plastic particles, comprises the following steps of a. extruding, placing amino molding plastics into the screw extruder through the feed valve to be heated, extruded into blocks, and transported into the roller machine; b. cooling, rolling blocks of amino molding plastics into sheets by the roller machine to be transported to the net belt and removed into the cooling device for cooling; c. crushing, removing the cooled amino molding plastics from the discharging valve into the crusher for crushing into particles; d. packaging, sieving the crushed particles through the screening machine for batch packaging. The amino molding plastic particles produced by the invention have stable physical properties, few chemical volatiles and stable liquidity, which are quite durable to be maintained for 12 to 24 months.

Description

Technical field [0001] The invention relates to a granulation process of amino molding compound particles. Background technique [0002] Amino molding compound (commonly known as electric jade powder) has played a very important role in the field of chemical materials, especially the production process of forming electric jade powder into pellets is very important. The process of granulating electric jade powder mainly includes kneading, drying and cooling. , Crushing and packaging. At present, the kneading process of domestic electric jade powder granulation mainly consists of urea, formaldehyde, wood pulp, titanium dioxide and other raw materials through the reaction pot kneading reaction. This kind of product has a complicated process and requires steam and a reaction pot. The physical properties are unstable, the chemical volatiles are many, the fluidity is easy to change, and the shelf life is about 3-6 months; therefore, the easy flow performance and strength of the electri...
