Abstract
The invention relates to a material for cosmetic bottle caps, which is prepared from the following components in percentage by weight: 30-35% of melamine formaldehyde resin, 20-30% of alpha-cellulose, 20-30% of filler, 0-2% of curing agent, 0-1% of colorant and 0-2% of assistant. The production technique comprises the following steps: resin synthesis, raw material mixing, wet material drying, grinding and screening. The prepared material has the advantages of bright and uniform color on appearance and high hardness. The production technique is simple; and the reaction, mixing, drying and the like are completed in one vacuum stainless steel reaction kettle with stirring function, thereby ensuring the stable quality of the product.
Description
Technical field
The present invention relates to a kind of bottle lid of cosmetics material and production technique thereof.
Background technology
At present, bottle lid of cosmetics both domestic and external with the material employing take urea--formaldehyde resin is base material, wood pulp cellulose is filler, add solidifying agent, lubricant, the made powdery moulding compound of pigment, form through the molding compacting, this material is owing to the impact that is subjected to domestic production equipment, technique, technology, so that when the compacting bottle lid of cosmetics, be prone to that outward appearance is not bright-coloured, color and luster is inhomogeneous, the not high quality factor of hardness.
Summary of the invention
The purpose of this invention is to provide and to make a kind of bottle lid of cosmetics material and the production technique thereof that product colour is bright-coloured, color and luster is even, hardness is good.
The technical scheme that the present invention takes is: a kind of bottle lid of cosmetics material is characterized in that its component is by weight percentage: terpolycyantoamino-formaldehyde resin 30～35% ,@Mierocrystalline cellulose 20～30%, filler 20～30%, solidifying agent 0～2%, tinting material 0～1%, auxiliary agent 0～2%.
Described@Mierocrystalline cellulose is wood pulp or cotton pulp.
Described filler is talcum powder, or barium sulfate, or the sheet Calucium Silicate powder.
Described tinting material is titanium dioxide, or phthalocyanine blue, or fluorescence is orange, or ultramarine, or precious red.
Described solidifying agent is polypropylene glycol, or phenylformic acid, or stearic acid list glyceride.
Described bottle lid of cosmetics comprises the following steps: with the production technique of material
A) resin is synthetic: press 1:1.6～2.2 molar ratio weighing trimeric cyanamide and formaldehyde, first formaldehyde is put into stainless steel cauldron, start stirring, pH value by adding formaldehyde in a certain amount of alkali conditioned reaction still is between 8.5～9.5, then add while stirring trimeric cyanamide, after adding trimeric cyanamide, beginning is heating slowly, under 80 ℃～95 ℃ temperature condition, reacted 90～150 minutes, add the trolamine neutralization, chuck water flowing cooling is stirred to resin temperature≤60 ℃, gets terpolycyantoamino-formaldehyde resin;
B) raw material mixes: under agitation terpolycyantoamino-formaldehyde resin is cooled to below 60 ℃, add wood pulp, filler, tinting material and auxiliary agent by above-mentioned weight percent again, heating makes that temperature of charge remains on 50 ℃～60 ℃ in the reactor, stirs to obtain wet feed in 40～60 minutes;
C) wet feed oven dry: with condenser cooling water valve open, vacuum pump open, jacket steam valve open, reactor emptying valve slowly closing, under-0.05Mpa condition, when temperature of charge reaches 85 ℃～95 ℃, close the chuck steam valve, open the reactor blow-off valve, close vacuum pump, close condenser cooling water, afterwards discharging;
D) grind screening: the material that drying is good adds in the ball mill, be milled to certain fineness after, sieve with the above sifting machine of 80 orders, can obtain the bottle lid of cosmetics material.
Adopt material that the present invention makes not only bright-colored in appearance, color and luster is even, and hardness is good, and it is simple to make technique, reaction, batch mixing, drying etc. are all finished in the stainless steel cauldron of cuff stirring, vacuum, have guaranteed the steady quality of product.
