Abstract
The present invention relates to calcium carbonate field, it discloses a kind of shutter leaf modified heavy calcium carbonate, is prepared by following raw material:100 parts of powdered whiting, 0.5 1 parts by weight of cetanol sodium sulfovinate, 12 parts by weight of odium stearate, 0.5 1 parts by weight of silicone coupling agents.The purpose of the present invention is a kind of shutter leaf modified heavy calcium carbonate of low reunion of offer.
Description
Technical field
The present invention relates to calcium carbonate field, particularly a kind of shutter leaf modified heavy calcium carbonate.
Background technology
Powdered whiting is to be ground to form by natural carbonate mineral such as calcite, marble, lime stone.It is common powder
Shape inorganic filler, have chemical purity is high, inertia is big, be not easy to chemically react, heat endurance is good, will not be decomposed below 400 DEG C,
Whiteness is high, oil absorbency is low, index of refraction is low, matter is soft, it is dry, without the crystallization water, the low wearing valve of hardness it is small, it is nontoxic, tasteless, odorless,
The advantages that good dispersion.The shape of powdered whiting is all irregular, its granular size differs greatly, and particle has necessarily
Corner angle, rough surface, particle diameter distribution is wider, and particle diameter is larger, and average grain diameter is generally 1 ~ 10 μm.This also brings heavy carbonic acid
Some shortcomings of calcium in application process, such as easily reunite.This shortcoming shows the most obvious in stone molding product.
Excessive reunion easily makes product fracture, and yields declines.
The content of the invention
The object of the present invention is to provide a kind of shutter leaf modified heavy calcium carbonate of low reunion.
The technical scheme is that：A kind of shutter leaf modified heavy calcium carbonate, passes through following raw material system
It is standby to obtain:
100 parts of powdered whiting, cetanol sodium sulfovinate 0.5-1 parts by weight, odium stearate 1-2 parts by weight, silicone coupling agents
0.5-1 parts by weight,.
In above-mentioned shutter leaf modified heavy calcium carbonate, it is prepared by following raw material:
100 parts of powdered whiting, cetanol sodium sulfovinate 0.6-0.8 parts by weight, odium stearate 1.3-1.8 parts by weight, siloxanes
Coupling agent 0.7-0.9 parts by weight.
In above-mentioned shutter leaf modified heavy calcium carbonate, the silicone coupling agents are vinyl trimethoxy
Silane or γ-aminopropyl triethoxysilane.
Meanwhile the invention also discloses a kind of preparation method of shutter leaf modified heavy calcium carbonate, the method
Specially：Cetanol sodium sulfovinate, odium stearate, silicone coupling agents are added drop-wise in dry-blender with powdered whiting,
The mixed at high speed 20-30min under conditions of 70-80 DEG C, to obtain the final product.
Beneficial effects of the present invention are as follows：
The present invention by 16-18 alkyl salt and 18 carbene compound combinations, silicone coupling agents compared to soap itself and again
The combination dynamics of matter calcium carbonate is more preferable, and preferable package action can be preferentially formed on the surface of powdered whiting, forms one
Nucleocapsid mechanism, odium stearate, cetanol sodium sulfovinate form backbone in the shell layer surface, form a tri-layer sphere knot
Structure, spacing becomes larger between making powdered whiting particle, and reunion tendency diminishes.It is found through experiments that, using odium stearate, cetanol
For sodium sulfovinate compared to odium stearate is used alone, the qualification rate for the louver being prepared has reached more than 93%, and only adopts
The louver qualification rate that the powdered whiting being modified with odium stearate is prepared can only maintain 80-85%.
Embodiment
With reference to embodiment, technical scheme is described in further detail, but is not formed pair
Any restrictions of the present invention.

The present invention by 16-18 alkyl salt and 18 carbene compound combinations, silicone coupling agents compared to soap its
It is more preferable with the combination dynamics of powdered whiting, preferable package action can be preferentially formed on the surface of powdered whiting, is formed
One nucleocapsid mechanism, odium stearate, cetanol sodium sulfovinate form backbone in the shell layer surface, form a tri-layer sphere
Structure, spacing becomes larger between making powdered whiting particle, and reunion tendency diminishes.It is found through experiments that, using odium stearate, spermaceti
Alcohol sulfuric ester sodium has reached more than 93% compared to odium stearate, the qualification rate for the louver being prepared is used alone, and only
