Abstract

The invention discloses an environmentally-friendly fast-curing long-storage-time amino molded granule and a production method thereof. Raw materials for preparing the granule comprise an aqueous solution of formaldehyde, urea, melamine, assistants, caustic soda and a filler. The filler is a pulp board, waste paper wood pulp, wood powder, vegetable fiber or husk, bone meal, starch and inorganic oxide mixture, and the assistants comprise urotropine, oxalic acid, water, ammonium sulfamate, magnesium oxide, zinc oxide, ammonium chloride, ethanol, triethanolamine, ammonia water, PPG, T-8, sodium naphthalene sulfonate, glycerin, magnesium carbonate, resorcinol, a pigment and zinc stearate. The production method of the environmentally-friendly fast-curing long-storage-time amino molded granule comprises the following steps: 1, synthesizing resin through a general alkali-acid-alkali technology, inputting the resin and the filler into a vacuum granulating reaction kettle in an evaporative concentration phase, and completing closed production in a one step manner.

Description

technical field [0001] The invention relates to the field of plastics, in particular to the production process of environment-friendly amino molding pellets. Background technique [0002] With the advancement of human civilization, people's awareness of environmental protection is getting stronger and stronger, and their requirements for green and environmental protection are getting higher and higher, and plastics that are close to people's lives have attracted more attention from consumers. Many non-toxic, harmless, non-polluting and degradable new plastic varieties have been widely used in furniture and building materials decoration, daily necessities, handicrafts, tableware and other fields due to their convenient processing and molding, bright colors and low cost. The use of wood flour, sawdust, shavings, plant fibers, husks, shell powder, starch and inorganic oxides to improve thermosetting resins is a type of non-toxic and harmless plastic products. [0003] At pres...
