Abstract
The invention relates to a preparation method of a color-glazed reflective paving stone. The preparation method comprises green body molding and sintering processes, wherein the green body comprises the following components in percentage by mass: 50%-70% of coal gangue, 20%-30% of soft clay, 4%-10% of potash feldspar, 4%-10% of sand slime and 1%-6% of ceramic soapstone; the green body molding process comprises the following steps: adding water to the mixed green body components, pugging through a pug mill, entering a molding extruder, and molding through an extrusion mold; the sintering process comprises the following steps: firstly drying the extruded green body, spraying glaze on the green body surface and then sintering. The color-glazed reflective paving stone prepared by the method has the advantages of good compressive strength, toughness, weather fastness and acid-base resistance properties; solid wastes and weathered stones of affecting vegetation growth are mainly utilized; and the preparation method is low-carbon, environmentally friendly and energy-saving.
Description
Technical field
The present invention relates to and pave the way by material of construction, the specifically preparation method of the reflective curb of a kind of color glaze-surface.
Background technology
Existing curb is all generally be made up of the cement demoulding, or Granite-cutting forms, and shortcoming is that ultimate compression strength and shear resistant are poor; Weather-proof, acid-and base-resisting is low, decortication variable color of a specified duration, the life-span is short, often within 2 ~ 3 years, heavily will spread, and cause significant wastage; Surface strength low very easily weathering airborne dust, pollutes; Surface irregularity, easily dirty, affect environmental beauty.
In addition, traditional working method is after starting material are marched into the arena, after one-level is pulverized, connect after various crushed stone weighs by proportional quantity, the rotation loaded again through nearly 40 hours in water mill is made through pressure filter filtering moisture after mud, then powder process after drying, more stand-by after mist projection granulating; Installation cost spent by this materials processing mode, the electricity charge, artificial etc. high, factory site takies very large, not only not environmentally but also waste energy.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method with high compressive strength, toughness and the reflective curb of color glaze-surface that is weather-proof, resistance to acids and bases.
For solving above technical problem, the technical solution used in the present invention is:
The preparation method of the reflective curb of a kind of color glaze-surface, comprise blank forming and sintering process, base substrate comprises the component of following quality than content: coal gangue 50-70%, soft clay 20-30%, potassium felspar sand 4-10%, purple clay 4-10%, ceramic talcum 1-6%, described blank forming adds water through pug mill pugging by the body composition after mixed, then enters forming extruder through extruding abrasive tool moulding; Described sintering is that the base substrate extruded first is carried out drying, then to billet surface glaze spraying, then sinters.
Wherein, soft clay is the epidermis of bauxitic clay, and viscosity is large, beautiful appearance, cracking resistance line, and firing temperature is low; Pottery talcum is the one of talcum, and purity is high, high containing magnesium, can increase the compactness of product by cracking resistance line; The effect of purple clay is the wear resistance of enhancing product and reduces the firing temperature of product thus reduce fuel power consumption.Add nonferrous metal oxides colorant and reflective powder or luminescent powder in glaze slip, increase the brightness that zinc oxide increases glaze paint, cupric oxide is the colorant of golden glaze, and glass microballon is the additive in reflective glaze, adopts different colorant to burn the color of various texture.
As preferred scheme, base substrate comprises the component of following quality than content: coal gangue 60%, soft clay 23%, potassium felspar sand 8%, boccaro 6%, ceramic talcum 3%.
As the preferred scheme of another kind, Temp. control method during sintering is: 20 DEG C → 80 DEG C intensification 3h, constant temperature 2h; 80 DEG C → 300 DEG C intensification 4h, constant temperature 2h; 300 DEG C → 700 DEG C intensification 6h, constant temperature 1.5h; 700 DEG C → 900 DEG C, intensification 3h, constant temperature 5h; 900 DEG C → 1200 DEG C intensification 3h constant temperature 3h.When base substrate is warming up to 80 DEG C, in base substrate, moisture starts to discharge, need whole constant temperature, subordinate phase: 80-300 DEG C belongs to the draining gas stage, need slowly carry out, phase III 300 DEG C → 700 DEG C is the physical reaction stage of various material in base substrate, and 700 DEG C of-900 DEG C of-900 DEG C-1200 DEG C these one-phases are chemical reaction stages of blank of material;
Adopt the reflective curb of color glaze-surface for preparing of the inventive method, there is good ultimate compression strength, toughness and weather-proof, resistance to acids and bases.Ultimate compression strength > 410Mpa, shear strength > 50Mpa.Weathering resistance: subzero 80 DEG C keep 3 hours, and the product of burning till are not any change.Put into sodium hydroxide saturated solution and within 48 hours, sweep finished product main body and glaze paint is not any change; In hydrochloric acid soln, (concentration 80%) immersion 48 hours main bodys and glaze paint are without any reaction.
Its vivid glaze paint, has security warning and road landscaping effect, nondiscoloration, fades, and glaze paint wear resistance is high.
Raw ore is machined to fineness used by the present invention's starting material mining point Raymond mill used, by bulk vehicle fortune as production plant, and squeeze in filler bin, being assigned in collecting bin through rear class of weighing then stirs stand-by, shared factory site comparatively traditional way saving 3/4 under equal conditions, energy consumption saves 3/4, and totally-enclosed operation is without any pollution.
Mostly what the present invention utilized is solid waste and affects the land waste of vegetation growth, low-carbon environment-friendly, energy-conservation.
