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:
the present invention relates to plastic applications, relate in particular to environment-friendly type amino film plastics production technique.
Background technology
Along with the propelling of human civilization, the environmental consciousness of people is more and more stronger, requirement that is green to clothing, food, lodging and transportion--basic necessities of life, environmental protection is also more and more higher, and the plastics pressing close to the life of people enjoy the concern of human consumer especially, research staff has released one after another many nontoxic, harmless, pollution-free, degredation plastic new variety, because its machine-shaping is convenient, bright in luster, cost is low, extensively should in fields such as furniture building materials and ornaments, daily necessities, artwork, tablewares.Utilizing wood powder saw powder shaving, vegetable fibre, paddy shell, carapace powder, starch and inorganic oxide etc. to improve thermosetting resin, is exactly the class in nontoxic, harmless plastics.
The amino Moulding powder processing method of current domestic production is for raw material with formaldehyde, urea, trimeric cyanamide etc., by integrating slurrying with filler, dry with mesh bag drying baker, formation plate mould material, then carry out pulverizing, ball milling, make melamine moulding powder, whole production process about 8 hours.This mode labour intensity is large, big energy-consuming, and have pollution to environment, have infringement to human body, the dust of finished product is many, density is low, appearance poor, Quality and yield is all difficult to effective raising.
summary of the invention:
The materials such as the raw material of the material in the method for a kind of quick production amino film plastics of the present invention is formalin, urea, trimeric cyanamide, auxiliary agent, caustic soda, packing material form.Wherein the parts by weight of each component are respectively: formalin 7-30, urea 4-18, trimeric cyanamide 1-5, auxiliary agent 0.1-0.2, packing material 10-85, and described packing material is pulp board, waste paper wood pulp, wood powder, vegetable fibre or paddy shell, bone meal, the mixture of starch and inorganic oxide, and pulp board, waste paper wood pulp, wood powder, vegetable fibre or paddy shell, bone meal, the weight ratio of starch and inorganic oxide is 50-90:6-20, and described inorganic oxide is selected from calcium oxide, magnesium oxide, aluminum oxide and kaolin etc., described auxiliary agent is trolamine, ammoniacal liquor, urotropine, ammonium chloride, oxalic acid, glycerine, magnesiumcarbonate, Resorcinol, phenol, sodium naphthalene sulfonate, colorant, methyl alcohol, ethanol, with Zinic stearas etc., the production method of the method for described a kind of quick production amino film plastics, for the resins synthesis stage: the alkali-acid-alkali method synthetic resins of gating, evaporation polycondensation phase: by the vacuum granulation reactor all-in-one of resin and packing material input designed, designed, there is polymerization, mediate, dispersion, closed production one step of the functions such as drying completes, and whole process can complete for two hours.
Technical scheme of the present invention realizes like this, contriver is through the experimental study of long period, to the proportioning of thermosetting resin and packing material, and the adding technology of packing material, selecting etc. of packing material proposes preferably scheme and particulate material production method.In a kind of method of quick production amino film plastics, the parts by weight of raw material are: formalin 7-30, urea 4-18, trimeric cyanamide 1-5, auxiliary agent 0.5-3, packing material 10-85, caustic-soda aqueous solution is appropriate, trimeric cyanamide mentioned here and urea to be its content be more than 95% solid, formalin to be its content be 37% formalin, as content has change, then to do to want corresponding adjustment to proportioning.Production process is: be the resins synthesis stage: the alkali-acid-alkali method synthetic resins of gating, packing material is added by resin liquid, with designed, designed by general-purpose equipment reactor, kneader, mixing machine, the function combinations such as vacuum become vacuum granulation reactor all-in-one, fully be uniformly mixed, 230pin stirs after 2 ~ 5 minutes, turn 120pin, material reaction temperature is incubated 40 minutes under 45-60 degree, unlatching vacuum valve draws water, stirring at low speed 10 ~ 15 minutes, transfer interval high-speed stirring to, temperature of charge 70-80 DEG C, moisture is measured after 20 minutes, meet decompress(ion) cooling blowing after moisture requirement, amino granular molding compound, omnidistance tasteless without bisque quality better, cost-saving raising effect.
beneficial effect:
1, the present invention is after thermosetting resin end of synthesis, and resin and packing material are inputted in the vacuum granulation reactor all-in-one of designed, designed, closed production one step with functions such as polymerization, kneading, dispersion, dryings completes.Omnidistance needs 2 hours, tasteless without bisque quality better, cost-saving raising effect.
2, packing material is: the mixture of pulp board, waste paper wood pulp, wood powder, vegetable fibre or paddy shell, bone meal, starch and inorganic oxide, cost is low, and performance is good.
3, improve Performance Strength owing to adding inorganic oxide etc. than single pulp board, waste paper wood pulp, wood powder, vegetable fibre or paddy shell, bone meal, starch finished product, expand the use range of such material.
