Abstract
The invention discloses a making method of surface modified talcum powder of composite modified, which is characterized by the following: weighing talcum powder; loading talcum powder in the high-speed blender; preheating material; stirring in the high-speed blender for 20 min; controlling the temperature not more than 90 deg.c; weighing diluent water; setting the weight rate of KH-550 silane coupling agent and water at 1:1-10; allocating composite surface modified solution through weight material, KH-550 silane coupling agent and sodium stearate with the weight rate at 100:0.4-2.5:0.5-2.0; pouring KH-550 silane coupling agent and sodium stearate into container to stir evenly; pouring high-speed mixed materials and surface modified solution into high-speed blender slowly to mix 10-30 min; controlling the temperature not more than 100 deg.c.
Description
Technical field
The present invention relates to a kind of method of modifying of natural talcum powder.
Background technology
Talcum is a kind of aqueous silicate minerals with laminate structure, is alkalescence in the water part omitted, and pH value is 9.0～9.5.Its chemical formula is: 3MgO4SiO
2H
2O has soft soapy feeling, its color adularescent, Steel Gray, light green and faint yellow multiple, and the paper grade (stock) talcum powder is a white.Its crystalline form has oblique system or hexagon or rhombus platelike crystal, sheet, flakey or compact mass aggregate commonly used.Talcous major ingredient is SiO
2, MgO and CaO etc., other compositions are less.Talcum structure unit interlayer maintains mutually with molecular linkage, and the interlayer section exists ionic linkage, covalent linkage.Two structural unit interlayers are interlamination region, and not moisture and positively charged ion only depends on faint van derwaals to connect between unit layer, so the very easy LED reverse mounting type that is dissociated into, talcum has two kinds of surface characteristic, and one is levels surface (aspect) the Si-O-Si configuration in the structure, not charged in theory, free of surface defects is the torpescence saturation plane, have inertia, hydrophobic character, no hydration layer, and the Si-O key is very strong, oxygen is broken away from be difficult to, so theoretically can't with the coupling agent combination, only may have adsorption; Another is a Si-O-Si N-type waferN section (end face), because its valence link fracture, energy is very high, the energy water dissociating, and so the hydrophilic feature of tool is the activity of showing as.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of composite modifier surface modified talcum powder, this method is raw material with the talc powder body, add properties-correcting agent talcum is carried out surface modification, surface-modifying agent is erected a molecule bridge between organic filler and organic polymer, with the polarity difference, two kinds of very poor material couplings of consistency are got up.Talcum is carried out surface modification improve the talcum wettability of the surface, dispersiveness and wetting ability, thus can strengthen the interaction of talc filler and matrix resin, can be widely used in fields such as polypropylene, polyethylene, polyvinyl chloride, high-impact polystyrene and ABS.
A kind of preparation method of composite modifier surface modified talcum powder is characterized in that this method comprises the steps:
1) takes by weighing the talc powder body material, in the surface modification of packing into the equipment temperature controllable high-speed mixer;
2) pre-thermal material makes the talc powder body material stir about 30min in temperature controllable high-speed mixer high speed, makes the powder material preheating, controlled temperature≤90 ℃;
3) take by weighing composite modifier KH-550 silane coupling agent, sodium stearate; Part by weight is pressed material: the KH-550 silane coupling agent: sodium stearate=100: 0.4-2.5: 0.5-2.0; The part by weight of KH-550 silane coupling agent and water is 1: 1-10;
4) the preparation surface modification solution is poured the composite modifier that takes by weighing in the container that thinner is housed into, and is stirred;
5) high-speed mixing material evenly, is slowly poured the surface modification solution of being prepared in the talc powder body material of high-speed mixer, and high-speed mixing 10～30min, controlled temperature≤100 ℃.
The invention has the beneficial effects as follows: be thinner with water, reduce the pollution of organic solvent environment; Anion surfactant mainly is longer chain fatty acid and sodium salt thereof, its action principle is: hydrophilic group in the anion surfactant and oleophilic group interact with magnesium hydroxide and polymkeric substance respectively, improve dispersiveness and the consistency of magnesium hydroxide in polymer materials, thereby improved the mechanical property of fire retardant material; Silane coupling agent is the low molecule silicoorganic compound with special construction because of it, and is remarkably productive to intensity and the thermotolerance of improving packing material; The sodium stearate hydrolysis spends a certain amount of ion, makes the aqueous solution become alkalescence, helps the hydrolysis of silane coupling agent in water, and the dual function of the two makes the steatitic surface modification effect for best.
