Problems solved by technology

Utilizing plant fibers, grain husks, inorganic oxides, etc. to improve thermosetting resins is a type of non-toxic and harmless plastic products. However, in the current production, there are two defects in the following aspects: First, in the production process, Production enterprises all use thermosetting resin powder, and then add filling materials for secondary mixing, which is very easy to mix unevenly, which not only increases the process, but also increases the production cost; the second is to use plant fiber, grain, and fruit shell as filling Materials without adding other filling materials such as enhancing strength or increasing gloss, so that the strength of the product is not high and the surface lacks luster

Embodiment 1

[0011] Example 1: Take 30 kg of formaldehyde and add it to the reaction kettle, stir for about 5 minutes, adjust the pH to 7.8-8.5 with caustic soda, add 11 kg of melamine, 3.5 kg of urea, continue stirring and raise the temperature to above 80 degrees within 15-20 minutes , keep warm at 80-90 degrees for 40 minutes, add 0.15 kg of triethanolamine, 0.1 kg of urotropine, 0.2 kg of glycerin, 0.1 kg of magnesium carbonate, 0.2 kg of resorcinol, 0.2 kg of sodium vegetable sulfonate, zinc stearate 0.15 kg, etc., after 10 minutes of heat preservation and stirring at 80-90 degrees, vacuum dehydration (about 10 minutes), put the material into a kneader, and add 30 kg of fruit shell powder and bone powder in turn under stirring. 15 kg of calcium oxide, 5 kg of magnesium oxide, fully stirred (about 2-5 minutes), directly into the mold for hot pressing, or put the material into the oven, the temperature of the oven is kept at 85-90 degrees, and place about three Hours, the material is in...

Embodiment 2

[0012] Embodiment 2: Get 20 kilograms of formaldehyde and add in the reaction kettle, process is as above, add 9.5 kilograms of melamines, the weight of all the other materials is constant, after the synthetic reaction finishes, and through vacuum dehydration. Get 25 kilograms of this material and put into the kneader, under stirring state, add successively 69 kilograms of waste cotton fiber powder, 6 kilograms of magnesium oxides, following operation process is as described in embodiment 1. This material can be used to produce high-strength, impact-resistant, tensile-resistant labor protection products, which are beautiful, generous, and unbreakable. It can also be used to make tableware, handicrafts, etc., which are environmentally friendly, economical, and affordable.

[0013] It is also possible to use crop orange stems, add starch as filling material, and add appropriate amount of inorganic oxides to produce environmentally friendly plastics. Using this to make handicrafts...

Abstract

The invention discloses a productive technology of modified thermosetting resin and formulation of environmental protection plastic. The formulation and proportion by weight is following: 3-13 melamine, 7-30 formaldehyde, 2-15 aquacare, 0,5-3 adjuvant, 10-85 filling material which is plant fiber, shell powder, bone meal, shellfish meal, or inorganic oxidate, caustic soda and water. The production method of environmental protection plastic comprises the following steps: the synthesis reaction of melamine, formaldehyde and aquacare, adding the adjuvant, after synthesis reaction, putting the filled composite into kneader, after sufficient mixing, putting the mixture into shaping machine to thermoform, keeping the product at 85-100Deg.C for hours according to requirement. The said material can be used to make high-grade dinner set, art ware, decorative building material and so on.

Description

Technical field: [0001] The invention relates to the field of plastics, in particular to environment-friendly plastics and a production method thereof. Background technique: [0002] With the advancement of human civilization, people's awareness of environmental protection is getting stronger and stronger, and the requirements for green and environmental protection in basic necessities of life are getting higher and higher, and the plastics that are attached to people's lives have attracted the attention of consumers. Many non-toxic, harmless, non-polluting and degradable new plastic varieties have been widely used in furniture, home decoration, daily necessities, tableware and other fields due to their convenient processing and molding, bright colors and reasonable prices. Utilizing plant fibers, grain husks, inorganic oxides, etc. to improve thermosetting resins is a type of non-toxic and harmless plastic products. However, in the current production, there are two defects ...
