The objective of the invention is the weak point at above-mentioned Handicraft decorative stone material existence, a kind of power up process stone and moulding process thereof are provided, power up process stone has lithotome tone texture, be rich in artistic appeal, the intensity height, carrying capacity is big, water-tolerant, contamination resistance is strong, has certain ventilation, water-absorbent, weathering resistance is good, is a kind of good artistic design, ornament Artistic stone material, its forming process novelty, it is convenient to make, and cost is low pollution-free.
Power up process stone and moulding process thereof take following scheme to realize: power up process stone is by various chromatic natural or artificial stone flours, natural or artificial color sand, and cement, water mineral color additive composition is formed.Power up process stone composition scope is:
Natural or artificial stone flour 20%~40% (weight)
Natural or artificial color sand 20%~65% (weight)
Cement 10%~30% (weight)
Water 5%~20% (weight)
Mineral color 0%~5% (weight)
Additive 0%~5% (weight)
The each component summation is 100% (weight)
Wherein additive can adopt acrylic ester emulsion, phenylpropyl alcohol carboxyl emulsion.
Power up process stone forming process:
1, weighing composition raw material according to a certain ratio: the natural or artificial color sand of various chromatic natural or artificial stone flours, cement, water, mineral color, additive are standby,
2, earlier chromatic natural the or artificial stone flour of siccative, natural or artificial color sand, cement, mineral color are stirred,
3, water and additive are added in the above-mentioned siccative that stirs slowly further stir again, make blank,
4, with the mould coated releasing agent of cleaning out, the above-mentioned blank of mixing thoroughly is added in the die cavity in batches, mechanical pudding,
5, the ambient cure demoulding in 24~48 hours,
6, normal temperature or vapor cure, vapor cure 24~48 hours, normal temperature maintenance 72~168 hours requires heat and moisture preserving, 15 ℃~40 ℃ of holding temperatures.
7, air-dry, 48 hours~72 hours time, finishing, polishing, cleaning,
8, coated surface treatment agent: optional unsaturated polyester resin solution, a kind of or compound coated in polyurethane resin solution, benzene emulsion, the acrylic ester emulsion 1~3 time, drying.
9, coated methyl silicon resin solution is 1~3 time.
10, promptly make power up process stone finished product after the thorough drying.
Power up process stone has lithotome color harmony texture, rich color, be rich in artistic appeal, the high carrying capacity of intensity is big, and contamination resistance is strong, good waterproof performance, have certain ventilation, water-absorbent is not fired, and is not afraid of sunshine, weathering resistance is good, can be used as a kind of good permanent molding artistic design stone material, building, ornament material, applied range.Power up process novel unique, the making facility of technology of doing made of stones, cost is low, pollution-free generation in the making processes.Can be made into dead front type and air-permeable product.
Embodiment 1: make power up process stone 100kg
It is 1, by proportioning weighing composition raw material: chromatic natural or artificial stone flour 20kg (weight proportion 20%), natural or artificial color sand 50kg (weight proportion 50%), cement 20kg (weight proportion 20%), water 10kg, standby,
2, earlier chromatic natural the or artificial stone flour of siccative, natural or artificial color sand, cement are stirred,
3, water is added slowly further to stir in the above-mentioned siccative that stirs again and makes blank,
4, with the mould coated releasing agent of cleaning out, the above-mentioned blank of mixing thoroughly is added in the die cavity in batches, mechanical pudding,
5, the ambient cure demoulding in 24 hours,
6, the normal temperature maintenance is 120 hours, requires heat and moisture preserving, holding temperature about 25 ℃,
7, air-dry 48 hours, finishing, polishing, cleaning,
8, coated acrylic ester emulsion, coated is 3 times continuously, drying,
9, coated first machine silicone resin is 1 time,
10, promptly make power up process stone finished product after the thorough drying.
Embodiment 2: make power up process stone 100kg
1, by proportioning weighing composition raw material: chromatic natural or artificial stone flour 30kg (weight proportion 30%), natural or artificial color sand 40kg (weight proportion 40%), cement 17kg (weight proportion 17%), water 5kg (weight proportion 5%), mineral color 5kg (weight proportion 5%), ACRYLIC EMULSION (additive) 3kg (weight proportion 3%), standby
2, earlier chromatic natural the or artificial stone flour of siccative, natural or artificial color sand, cement, pigment are stirred,
3, water, acrylic ester emulsion are added slowly further to stir in the above-mentioned siccative that stirs again and make blank,
4, with the mould coated releasing agent of cleaning out, the above-mentioned blank of mixing thoroughly is added in the die cavity in batches, mechanical pudding,
5, the ambient cure demoulding in 36 hours,
6, vapor cure is 48 hours,
7, air-dry, 48 hours time, finishing, polishing, cleaning,
