Abstract

The invention discloses a jade vein simulated high-intensity low-shrinkage amino moulding plastic particle material and a production method. The high-intensity low-shrinkage amino moulding plastic particle material is characterized by being prepared from formaldehyde water solution, urea, melamine, auxiliary agents, sodium hudroxide, filling materials and the like, wherein the filling materials are mixed bodies of wood powder, inorganic and organic medium short fiber, paper pulp plates, waste paper wood pulp, grain and fruit hulls, bone meal, starch and inorganic oxides; the auxiliary agents are urotropine, oxalic acid, water, ammonium sulfamate, magnesium oxide, zinc oxide, ammonium chloride, ethanol, trolamine, ammonia water, PPG, T-8, sodium-naphthalenesulfonate, glycerin, magnesium carbonate, hydroxyphenol, pigment, zinc stearate and the like. The production method of the jade vein simulated high-intensity low-shrinkage amino moulding plastic particle material comprises the following steps that in a resin synthesis stage, a general alkali-acid-alkali method is selected for synthesizing the resin; in an evaporation polycondensation stage, the resin and the filling materials are input into a vacuum granulation reaction kettle, and the sealed production is completed in one step.

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.
