Definitions
- the invention relates to the technical field of processing artificial stone, and more specifically, to an organic fiber toughened inorganic composite artificial stone panel and a preparation method thereof.
- Traditional artificial stone is mainly composed of resin organic artificial stone and a small amount of inorganic artificial stone.
- Resin artificial stone mainly has the disadvantages of large thermal deformation, easy drum deformation and cracking, aging deformation, discoloration, reduced strength due to ultraviolet radiation and temperature, unpleasant gas, non-degradable combustion, and short service life.
- the new inorganic artificial stone panels are currently mainly traditional cement-based terrazzo products, with low compressive strength, poor hardness, poor bending strength, strong brittleness, easy brittle fracture, high overall water absorption, stain resistance and chemical resistance Poor, it is difficult to achieve the performance of natural stone, the panel is easy to break, and it is not safe to use.
- the inorganic artificial stone itself has a brittle structure and is resistant to bending and breakage.
- Most of the artificial stone panel structure is a single-layer structure. When the structure is subjected to external force, the bottom directly cracks and causes brittle fracture. The structure is low in ductility and the product is directly damaged, so there is a structure A metal mesh or fiber mesh reinforcement structure (such as CN106630805A) is added in the middle to improve it. However, when the surface is compressed, the brittle surface at the bottom is still bent and deformed and brittle cracking occurs.
- the present invention overcomes the shortcomings of existing traditional inorganic artificial stone technology products such as insufficient compressive performance, poor bending strength and toughness, and high water absorption, and provides a high strength, pollution resistance, high toughness, long service life, and durability. Aging, economical and reasonable multi-layer composite structure organic fiber toughened inorganic composite artificial stone panel.
- the present invention adopts the following technical solutions:
- An organic fiber toughened inorganic composite artificial stone panel includes a surface layer, a middle organic fiber toughened layer, and a base toughened layer.
- the surface layer includes the following raw material components in parts by weight: quartz sand 40 to 70, quartz powder 10 to 30, Inorganic active powder 20 ⁇ 45, pigment 0.5 ⁇ 4, water reducing agent 0.3 ⁇ 1, water 3 ⁇ 10;
- the middle organic fiber toughening layer includes the following raw materials in parts by weight: inorganic active powder 40 ⁇ 60, sand 45 ⁇ 65, water reducing agent 0.8 ⁇ 1.5, water 6 ⁇ 14, organic fiber 0.5 ⁇ 1.2;
- the base toughening layer includes the following raw material components in parts by weight: inorganic active powder 30-50, quartz sand 30-55, Quartz powder 15-20, water reducing agent 0.5-1.2, water 4-8, toughening agent 0.8-2.5.
- the quartz sand has a fineness modulus of 2.0-3.0, a silica content of 93% or more, no impurities and weathering, and a rough hardness of 7 or more.
- the quartz powder has a fineness of 600 mesh or more, a silica content of 93% or more, and a rough stone hardness of 7 or more.
- the core function of the quartz powder in the present invention is to improve the wear resistance and scratch resistance of the gelled powder hydration product on the surface of the artificial stone after mixing except for the aggregate, and to improve the surface density performance.
- the inorganic active powder is mainly pure white Portland cement with a strength grade of 42.5 or higher, mixed with one of white silica fume, mineral powder, nano calcium oxide, nano silica silica, and sintered high white kaolin powder Or several active powders.
- the color of the active powder is single white, the whiteness index is more than 80, and the activity index detection is more than 100%, which ensures the strength of the material and also ensures good stability of subsequent toning.
- the ratio of cement to other active powders is 1:0.2 ⁇ 0.6.
- the pigment is an inorganic pigment of various colors.
