Embodiment 1

[0018] A method for preparing artificial colored sand, characterized in that it comprises the following steps:

[0019] a. Preparation of water-based epoxy resin emulsion:

[0020] 1) Weigh epoxy resin (E-44 2.850g) and polyethylene glycol (PEG-6000 35.782g) and polypropylene glycol (PPG-2000 0.627 g), put it into a three-necked flask equipped with a constant speed stirrer, a reflux condenser, and a dropping funnel, place the device in an oil bath, heat up to 90°C, and after 0.5h, the contents of the bottle melt into a liquid, and Stir at a speed of 500r / min. After uniformity, start to add 0.118g potassium persulfate (0.3%) initiator dropwise at 4 drops / min. After 9 minutes, the dropwise addition is completed. After keeping the temperature for 10 minutes, raise the temperature to 180°C and keep the temperature for 3 hours to obtain the emulsifier ;

[0021] 2) Take 2.954g of the above emulsifier and 8.868g of E-44 at a mass ratio of 1:3 and add them to a three-neck flask equ...

Embodiment 2

[0025] The preparation method of this embodiment is the same as that of Example 1, except that the sand grains are 40-80 mesh, 2800g of the water-based epoxy resin emulsion in Example 1, and 300g of curing agent T-31.

Embodiment 3

[0027] The preparation method of this embodiment is the same as that of Example 2, except that 800g of iron red is different.

Abstract

The invention discloses artificial colored sand which is prepared from a sand material, an adhesive, a curing agent and pigments, wherein the adhesive is water-borne epoxy resin and the curing agent is a room temperature curing agent T-31. The invention further discloses a preparation method of the artificial colored sand. The preparation method comprises the following steps: preparing the water-borne epoxy resin; preparing the sand material; blending colors; curing; and obtaining a finished product. The preparation method disclosed by the invention is characterized in that the self-made water-borne epoxy resin is used as the adhesive, and the artificial colored sand is prepared by using the normal temperature curing agent T-31. The colored sand is strong in wear resistance and acid and base resistance, pure in color and easy for color blending and suitable for preparing wide building and ornament materials and the like. The preparation process realizes room temperature production and has the advantages of convenience, energy conservation and environmental friendliness.

Description

technical field [0001] The invention relates to the field of functional sand materials, in particular to an artificial colored sand and a preparation method thereof. Background technique [0002] Colored sand has been widely used in the field of architectural decoration because of its bright colors and stable performance. As people's demand and quality requirements for colored sand are getting higher and higher, artificial colored sand has been greatly developed. There are many processes for the production of artificial colored sand. Generally, sand particles are obtained after crushing, screening, grading, polishing and other processes, and then dyed according to needs. The color of artificial colored sand is uniform and bright, and can be adjusted at will according to needs. However, the existing colored sand production technology generally has problems such as complicated preparation process, energy consumption, high cost, poor wear resistance of the product, and difficu...
