Embodiment 1

[0013] Embodiment 1: Get 240 kilograms of formaldehyde aqueous solution, 100 kilograms of urea, 13 kilograms of melamine, appropriate amount of water and auxiliary agent etc. and add in vacuum granulation reaction kettle all-in-one machine, select general-purpose alkali-acid-alkali method synthetic resin.

[0014] Add 65 kg of waste white paper pulp wood pulp and 12 kg of zinc stearate to the resin liquid, and fully stir and mix with 230 pins for 2 to 5 minutes, then turn to 120 pins, and the material reaction temperature is at 45 Keep warm at -60°C for 40 minutes, open the vacuum valve to pump water, stir at a low speed for 10-15 minutes, then switch to intermittent high-speed stirring, the temperature of the material is 70-80°C, measure the moisture after 20 minutes, decompress and cool down and discharge the material after meeting the moisture requirements, and it is ready. Amino molding compound.

Embodiment 2

[0015] Embodiment 2: get 300 kilograms of formaldehyde aqueous solution, 150 kilograms of urea, 30 kilograms of melamine, 0.01 kilogram of triethanolamine, 1 kilogram of urotropine, 0.1 kilogram of ammonium chloride, 0.2 of ethanol, 0.6 kilogram of oxalic acid, 2 kilograms of glycerin, magnesium oxide 0.01 Kg, 0.02 kg of resorcinol, 0.02 kg of sodium naphthalenesulfonate, 1.5 kg of zinc stearate, etc. and 10% methanol water are added to the vacuum granulation reactor integrated machine, and the resin is synthesized by the general alkali-acid-alkali method .

[0016] 350 kilograms of material wood flour, 150 kilograms of fruit shell powder, 20 kilograms of calcium oxide based on bone meal, and 15 kilograms of magnesium oxide are put into the all-in-one machine, and closed production such as polymerization, kneading, dispersion, and drying are carried out with example 1. Environmentally friendly, economical and durable amino molding pellets.

Embodiment 3

[0017] Embodiment 3: get 200 kilograms of formalin aqueous solution, 10 kilograms of melamines, same example 1, other material weights are constant, add in the all-in-one machine, process selects general-purpose alkali-acid-alkali method synthetic resin. The vacuum granulation reactor integrated machine is in the stirring state, adding 28 kg of waste cotton fiber, 26 kg of waste paper pulp powder, 33 kg of kaolin, 2 kg of color material, 0.6 kg of magnesium oxide, and 0.1 kg of magnesium carbonate. The operation process is as follows: Implementation, with Example 1, closed production such as polymerization, kneading, dispersion, drying. This material can be used to produce high-strength, impact-resistant, tensile-resistant labor insurance products, which are beautiful, generous, and unbreakable. It can also be used to make tableware, such as mahjong chess cards, flower pots, tableware, handicrafts, high-end decorative panels, and imitation solid wood furniture. And other ...

Abstract

The invention discloses a method for rapidly producing an amino molded material. Raw materials for producing the amino molded material 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, a weight ratio of pulp board, waste paper wood pulp, wood powder, vegetable fiber or husk, bone meal and starch to the inorganic oxide is 50-90:6-20, the inorganic oxide is selected from calcium oxide, magnesium oxide, alumina and kaolin, and the assistants comprise triethanolamine, ammonia water, urotropine, ammonium chloride, oxalic acid, glycerin, magnesium carbonate, resorcinol, phenol, sodium naphthalene sulfonate, a pigment, methanol, ethanol and zinc stearate. The production method of the environmentally-friendly amino molded material comprises the following steps: 1, synthesizing resin through a general alkali-acid-alkali technology, and inputting the resin and the filler into a vacuum granulating reaction kettle in an evaporative concentration phase, and completing closed production within 2h in a one step manner.

Description

Technical field: [0001] The invention relates to the field of plastics, in particular to an environment-friendly amino molding compound production process. 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 presen...
