Abstract
The invention discloses a preparation method of hydromagnesite packing filled with unsaturated polyester resin. The preparation method comprises the steps that hydromagnesite powder and titanium dioxide are compounded according to the mass ratio (95-98):(2-5) of the hydromagnesite powder to titanium dioxide to obtain compound powder; polyethylene glycol and triethanolamine are mixed according to the mass ratio (1-3):(1-3) of polyethylene glycol to triethanolamine and then fully stirred and mixed to be uniform by adding water to be prepared into a mixed modifying agent solution with the mass concentration of 25%-50%; the compound powder and the mixed modifying agent solution are weighed separately according to the mass ratio 100:(2-8) of the compound powder to the mixed modifying agent solution and synchronously metered and fed into continuous powder surface modifying equipment to be subjected to organic surface modifying treatment at the temperature of 70 DEG C-110 DEG C. According to the method, the hydromagnesite packing which is good in compatibility with the unsaturated polyester resin, high in whiteness and low in cost can be obtained by compounding the hydromagnesite powder and titanium dioxide and conducting organic surface modifying through the mixed modifying agent.
Description
Technical field
The present invention relates to a kind of basic magnesite filler preparation method filling unsaturated polyester resin, belong to mineral material and add
Work and applied technical field.
Background technology
Inorganic powder filled unsaturated polyester resin composite material is with unsaturated polyester resin as base material, and inorganic particle is
Filler, adds a certain proportion of auxiliary agent, mix by stirring, pour, be gelled, one that the operation such as solidification is made novel organic/
Inorganic compounding building and ornament materials.This composite is referred to as " artificial stone ".Owing to having safe and environment-friendly, no color differnece, color
The feature such as adjustable, is widely used in the indoor top grade decoration of hotel, office building, house etc..Unsaturated polyester resin is filled
Inorganic particle filler can play enhancing product strength, reduce the effect such as shrinkage factor, reduction cost.
Basic magnesite is a kind of natural hydrated basic magnesium carbonate mineral, and chemical composition is 4MgCO3·Mg(OH)2·4H2O,
It it is the high-quality magnesium ore resources originating in China's Tibetan Salt Lakes.Basic magnesite initial decomposition temperature, between 220-240 DEG C, decomposes and produces
Solid MgO be overlying on combustible surface and play the effect of fire-retardant oxygen barrier, the flue dust that burning produces can also be adsorbed simultaneously, reduce cigarette
Density；Decompose the gas H produced2O and CO2Around fuel gas and the concentration of oxygen can be diluted；The heat that decomposition reaction absorbs
The temperature of surrounding can be reduced, so basic magnesite can be as inorganic fire-retarded filler.It addition, basic magnesite quality is pure
Only, color and luster is pure white, and impurity content is low, and the basic magnesite powder body obtained after super-fine processing has good transparent and higher
Whiteness.Filling unsaturated polyester resin with hydromagnesite stone powder for filler, prepared organic/inorganic composite decorative building material has
The features such as decomposition temperature is high, smoke density is little, product cost is low.
Summary of the invention
On the basis of existing technology, the invention provides a kind of basic magnesite filler system filling unsaturated polyester resin
Preparation Method, by hydromagnesite stone ore after broken, grinding and surface organic modification, can obtain and the unsaturated polyester resin compatibility
Good, whiteness basic magnesite filler higher, lower-cost.
The technical solution used in the present invention: a kind of basic magnesite filler preparation method filling unsaturated polyester resin, main
Comprise the following steps that:
(1) by hydromagnesite stone powder: hydromagnesite stone powder is compounded by the mass ratio of titanium dioxide=95-98:2-5 with titanium dioxide,
To composite granule；
(2) Polyethylene Glycol is pressed: Polyethylene Glycol is mixed by the mass ratio of triethanolamine=1-3:1-3 with triethanolamine, then adds water
It is thoroughly mixed uniformly, is configured to the mixed and modified agent solution that mass concentration is 25-50%；
(3) by composite granule: the mass ratio of mixed and modified agent solution=100:2-8 weighs composite granule and mixed and modified respectively
Agent solution, and synchronous measurement feeds in continuous powdery surface modifying apparatus, carries out surface organic at a temperature of 70-110 DEG C
Modification.
Optimizing further, described in step (1), the particle size distribution of hydromagnesite stone powder is d50=2-8 μm, d90=20-70 μm,
dmax=60-120μm。
Optimizing further, titanium dioxide described in step (1) is the answering of any one or both in rutile-type, anatase titanium dioxide
Closing, whiteness is not less than 95%.
Optimizing further, in step (3), the mass ratio of composite granule and mixed and modified agent solution is specially composite granule:
Mixed and modified agent solution=100:3-6.
Optimizing further, continuous powdery surface modifying apparatus described in step (3) is that the continuous powder surface of SLG type changes
Property machine.
Hydromagnesite stone powder is compounded with titanium dioxide by the present invention, utilizes high whiteness and the high covering power of titanium dioxide, can
To improve the whiteness of basic magnesite filler further.After the blended modifying agent of hydromagnesite stone powder carries out surface organic modification, it is inhaled
Oil value significantly reduces, and enhances the compatibility between unsaturated polyester resin.So, in the present invention, the basic magnesite of preparation is filled out
Material is filled in unsaturated polyester resin, and loading is uniformly dispersed greatly and easily, and the composite obtained has good fire-retardant
Performance and mechanical property, compared with the most conventional filling aluminium hydrate, the unsaturated polyester resin that basic magnesite filler is filled
Heat stability improve, the production cost of product declines to a great extent.
