Description
1. technical field
The present invention relates to a kind of inorganic compounding and surface modifying method of wollastonite packing, belong to mineral material processing and Application Areas.
2. background technology
In macromolecular materials such as plastics, polymer matrix composite, functional high molecule material etc., be extensive use of through the inorganic nonmetal mineral fillers after the processing such as pulverizing, stepped surface modification.Its filling properties of decision such as the chemical ingredients of these inorganic nonmetal mineral fillers, crystalline structure, globule size and size-grade distribution, particle shape.Modern novel high polymer based composites not only requires inorganic nonmetal mineral fillers to have increment and reduces the effect of material cost, the more important thing is to have reinforcement and enhancement function.Therefore, the filling enhancing or the reinforcing property of raising inorganic nonmetal mineral fillers are one of inorganic nonmetal mineral fillers processing technology most important.Particle diameter miniaturization, chemical ingredients and crystalline structure are complicated, surfactivity and compatibilized are considered to improve the filling enhancing of inorganic nonmetal mineral fillers or the major technique approach of reinforcing property.Carried out more research for the superfine grinding processing technology of inorganic nonmetal mineral fillers and the surface organic modification activating technology of inorganic mineral filler.Existing superfine grinding and fine graded technology can satisfy the requirement of inorganic nonmetal mineral fillers particle diameter miniaturization basically, and the inorganic nonmetal mineral fillers after the organic surface modifying activation also is applied in macromolecular material such as plastics or superpolymer based composites.But, the cooperation optimization of, filler particles shape complicated and the processing of inorganic non-metallic mineral composite reactive filler and use and also seldom study for inorganic nonmetal mineral fillers chemical ingredients and crystalline structure.Because the difference of inorganic nonmetal mineral fillers particle shape, chemical ingredients, crystalline structure and the physicochemical property of different varieties, the influence of its mechanical property to filling superpolymer based composites, thermal property etc. is also with difference.Two or more inorganic nonmetal mineral fillers are carried out compound and organic surface modifying, make bulk structure complicated and the surfactivity and the compatibilized of filler systems, the inorganic nonmetal mineral fillers of variable grain shape, chemical ingredients, crystalline structure and physicochemical property organically combines, when filling, learn from other's strong points to offset one's weaknesses, cooperatively interact, can realize the optimization of inorganic nonmetal mineral fillers filling properties.
Wollastonite belongs to the chain metasilicate, and main chemical compositions is a Calucium Silicate powder; The crystallization of wollastonite is parallel to dissociating fully of (100) face, and the cleavage that is parallel to (001) and (102) face is also more obvious, even therefore fine particle also is fibrous or needle-like.Owing to it has the functional stuffing that good reinforcement, difficult combustion, performance such as wear-resisting, ageing-resistant are widely used as engineering plastics such as PP, PA, ABS.
The Simaldrate powder is an a kind of smectite family silicate minerals, and main chemical compositions is SiO
2, MgO, Al
2O
3Oblique system, laminate structure, between its structural unit filling water molecules and interchangeability positively charged ion, and can absorb organic molecule; Has flame retardant resistance, insulativity, the transparency, thermostability, reinforcement, smooth property, resistance to deterioration, uvioresistant, many performances such as brightening property.
Carry out the inorganic mineral powder of wollastonite and this different chemical composition of Simaldrate powder, different crystal structure and particle shape compound, and then compounded mix carried out surface organic modification, make compoundization such as chemical ingredients, crystalline structure, particle shape of filler, surface activation can significantly improve the filling properties of wollastonite packing in the superpolymer based composites.
3. summary of the invention
A certain amount of Simaldrate powder is added in the wollastonite packing, compound with the certain speed heated and stirred in stirring mixer, when waiting to rise to certain temperature, promptly obtain wollastonite inorganic compounding and surface modifying stuffing after adding a certain amount of silane coupler modified processing certain hour.
Its processing step is as follows:
(1) a certain amount of Simaldrate powder is mixed back limit heating in stirring mixer with wollastonite packing, the limit is stirred compound;
When (2) waiting to rise to certain temperature, add a certain amount of silane coupling agent carries out certain hour to compounded mix surface modification treatment.
Below be prescription of the present invention and main technique condition:
(1) addition of Simaldrate powder is Simaldrate powder/wollastonite packing (mass ratio)=(3～20)/(97～80);
(2) silane coupling agent is an aminosilane, and consumption is 0.5%～2.0% of wollastonite and a Simaldrate powder compounded mix quality:
(3) adding silane coupling agent is 60～120 ℃ to the temperature that compounded mix carries out surface modification;
(4) adding silane coupling agent is 5～45min to the time that compounded mix carries out surface modification.
Advantage of the present invention: wollastonite inorganic compounding and surface modifying stuffing with the present invention's preparation are filled intensity and the toughness that PA6 can significantly improve the PA6 based composites, as the simply supported beam notched Izod impact strength, tensile strength, Young's modulus, flexural strength and modulus in flexure etc.
