Abstract

The present invention relates to a cement coloring pigment and a preparation method thereof. The cement coloring pigment selects a vivid organic pigment and an inorganic pigment with good weather resistance to be proportionally mixed, and a colorful base material is obtained after a dispersing agent, a penetrating agent and water are added to be sanded in a sand mill; then the colorful base material and quartz sand or albarium are mixed to be ground in a high-speed dispersion machine, and a finished product composed of the quartz sand or the albarium, the organic pigment, the inorganic pigment, the penetrating agent and the dispersing agent is manufactured finally through the steps of coating, drying, pulverization and sieving. Because the present invention integrates the advantages of the organic pigment and the inorganic pigment, the present invention has the characteristics of favorable coloring power, good water wetting performance, light resistance, alkali resistance, low cost and good vivid degree; furthermore, the present invention can satisfy the requirements of customers at any time.

Description

Cement colouring agent and preparation method thereof

What the present invention relates to is that a kind of construction cement that is used for carries out painted synthetic chemical color.

People usually select materials such as coating, furring brick and colored cement for use when decorative constructure at present, yet because the coating of coating is thinner, during especially for the exterior wall of buildings, expose to the sun and rain, coating is easily aging to be peeled off, fades, though furring brick is more durable, but its color is few, cost an arm and a leg, be not suitable for the decoration of low and middle-grade residential houses, it can not overcome the shortcoming that comes off in addition simultaneously.Present colored cement then costs an arm and a leg, can not large-area applying.Current, domestic also have produce color concrete and goods thereof, their are most, and what use is the pigment of ferric oxide series, though the pigment price of this ferric oxide series is low, and fast light, alkaline resistance properties good, but color dimness, minority is used organic fast light pigment, though bright in luster, cost an arm and a leg, and the water wet performance is relatively poor, uses inconvenience.

Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned existence, and a kind of low raw material of cost that adopts is provided, and tinting strength is preferably arranged, the water wet performance, and preparation technology is simple, and the cement colouring agent that can apply and preparation method thereof.

The objective of the invention is to finish by following technical solution, it is mainly by quartz sand or white stone powder, pigment dyestuff and mineral dye, permeate agent, diffusant, water is formed, with bright-coloured, but expensive pigment dyestuff and inexpensive, but the mineral dye that the weathering resistance of color dimness is strong is admixed, the weight percent of each component is: pigment dyestuff 0.5-10%, mineral dye 3.5-20%, diffusant 0.01-0.8%, permeate agent 0.5-1.6%, water 1-5%, quartz sand or white stone powder 50-94%, and the amount of above each component mainly is to prepare according to user's needs.

The present invention selects for use dispersing agent MF as diffusant, selects for use sodium dibutyl naphthalene sulfonate as permeate agent, and the water content of its blending ingredients be controlled at total amount 1% in.

Cement colouring agent of the present invention makes by the following method, earlier that bright-coloured pigment dyestuff and weathering resistance is strong mineral dye is mixed in proportion, add diffusant, permeate agent, water again, said mixture is placed into carries out sand milling in the sand mill to obtain colored base-material, the sand milling time is long more, the particle of colored base-material is thin more, mixes even more; Again above-mentioned colored base-material is mixed with quartz sand or white stone powder and put in the high speed dispersor and grind, in like manner milling time is long more, mixture particle is thin more, mixes evenly more, and carrying out conventional coating, drying at last, pulverizing and sieving makes finished product, the per-cent that feeds intake (weight) of its each component is: pigment dyestuff 0.5-10%, mineral dye 3.5-20%, diffusant 0.01-0.8%, permeate agent 0.5-1.6%, water 1-15%, quartz sand or white stone powder 50-94%.

The present invention also can further select the per-cent that feeds intake of each component to be: pigment dyestuff 0.5-8%, mineral dye 3.5-15%, diffusant 0.01-0.2%, permeate agent 0.5-1.4%, water 1-6%, quartz sand or white stone powder 69-94%.

The present invention also can further select the best of each component per-cent that feeds intake, they are: pigment dyestuff 1.5%, mineral dye 3.5%, dispersing agent MF diffusant 0.05%, sodium dibutyl naphthalene sulfonate permeate agent 0.8%, water 2.5% and quartz sand or white stone powder 91.65%.

In above-mentioned preparation method, be placed in the sand mill sand milling 15-45 minute after can selecting each component of colored base-material to mix, with colored base-material with put into that milling time is 30-75 minute in the high speed dispersor after quartz sand or white stone powder mix.

It is 30 minutes that the present invention also can further select the sand milling time, and milling time is 1 hour, and drying is to carry out in being lower than 120 ℃ environment, make the water content of finished product be controlled at total amount 1% in.

It is inexpensive that the present invention collects the bright in luster and mineral dye of pigment dyestuff, advantages such as good weatherability, have good tinting strength, the water wet performance, fast light, alkaline-resisting, and above-mentioned colored base-material mixed with inexpensive quartz sand or white stone powder, the cost of product is reduced greatly, as 10 square metres of green terrazzo terraces, need 1 kilogram of chrome green, about 26 yuan of valency; And select for use product of the present invention only to need 0.7 kilogram, and price is about 7 yuan, and colour vividness is better than the former, so the present invention is as the interior wall face of buildings, the cement colouring agent on road surface, and its market outlook are boundless.

The present invention also can further specify by following embodiment.
