Abstract
The invention discloses a high-toughness mould pressing tile and a preparation method thereof. The tile is prepared from the following components in parts by mass: 5-8 parts of ramie fibers, 10-16 parts of two-component polyurethane, 50-150 parts of sands, 35-70 parts of cement and 20-50 parts of water, wherein the two-component polyurethane comprises polyaryl polymethylene isocyanate PAPI and a polyether component in a mass ratio of 2:3; the polyether component is obtained by mixing polyether 220, a diluting agent and an organic silicon defoaming agent in a weight ratio of (1-5):(1-3):(1-2); and the length of the ramie fibers is 5-30mm. The preparation method is simple in process and convenient to use, is capable of greatly improving the tensile strength and toughness of the tile and overcoming the defect that a common tile is easily broken and does not insulate; and the tile prepared by the method has water absorption rate being less than 3 percent, tensile strength being more than 5MPa and breaking strength being more than 8MPa, which are far superior to those of a current standard.
Description
Technical field
What the present invention relates to is a kind of cement tile, in particular a kind of high tenacity mold pressing tile and preparation method thereof.
Background technology
Cement tile is the abbreviation of color cement tile, because it uses starting material to be cement, therefore is often called cement tile.This product is formed through the press filtration of high-quality mould by high pressure.Thus the density of become goods is large, intensity is high, rainproof good frost resistance, and surfacing, size are accurate.Color cement tile color is various, and working life is long, low cost.It was both applicable to general bolts, was also applicable to the waterproof and heat-insulating of Deluxe villa and Highrise buildings.
Being subject to breakage at weather tile is modal a kind of situation.The walking that sometimes people is rough on roofing, or sometimes tile lay too close, also have house sunken regions all can cause the damage of tile.Tile, once damage, not only can leak, also can cause great potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of high tenacity mold pressing tile and preparation method thereof, improve the toughness of tile.。
The present invention is achieved by the following technical solutions, and the present invention by weight, comprises ramee 20 ~ 25 parts, dual-component polyurethane 10 ~ 16 parts, sand 50 ~ 150 parts, cement 35 ~ 70 parts, 20 ~ 50 parts, water; Described dual-component polyurethane comprises the poly methylene poly phenyl poly isocyanate PAPI and polyether component that mass ratio is 2:3, described polyether component is that Polyether 220, thinner, silicone antifoam agent 1 ~ 5:1 by weight proportion ~ 3:1 ~ 2 mix, and the length of described ramee is 5 ~ 30mm.
As one of optimal way of the present invention, the composite Portland cement of described cement to be intensity be 42.5R.
Described sand is the river sand that particle diameter is less than 0.8mm.The particle diameter of sand is less, and its bondability is also higher, and river sand price is low, and holistic cost reduces.
As one of optimal way of the present invention, described thinner is Virahol.
The proportioning of described each raw material is ramee 22 parts, dual-component polyurethane 13 parts, sand 115 parts, cement 55 parts, 35 parts, water.
A making method for high tenacity mold pressing tile, comprises the following steps:
(1) cement, sand, ramee and water are stirred in proportion;
(2) after the polyether component added in dual-component polyurethane stirs, and then add poly methylene poly phenyl poly isocyanate PAPI and stir;
(3) pressure filtration molding is carried out by the material stirred feeding mould cavity;
(4) deviate from from die cavity by the unbaked tile that pressure filtration molding obtains, rest 15 ~ 25 hours, then maintenance colouring can obtain finished product.
In described step (3), the shaping pressure of unbaked tile is 10 ~ 15MPa.
Be provided with filter screen between the bed die of described mould and unbaked tile, bed die is provided with water vent.
First add the polyether component in urethane, polyether component can be made easily to disperse in other components, then add poly methylene poly phenyl poly isocyanate PAPI and mix.What urethane can be made to disperse in the system of haveing suffered is more even.Two component polyurethane more easily disperses, and mono-component polyurethane is not easily uniformly dispersed, and the aquation of cement and the solidification of urethane are carried out simultaneously, is formed and mutually fills one-piece construction, thus improve the intensity of tile.Ramee is very tough and tensile, and brute force is large and extensibility is little, adds and is not subject to mold corrosion and damages by worms, effectively can improve the toughness of tile.
The present invention has the following advantages compared to existing technology: present invention process is simple, easy to use, ultimate compression strength and the toughness of tile can greatly be improved, overcome the frangible uninsulated defect of plain tiles, the tile that the present invention obtains, water-intake rate is less than 3%, and ultimate compression strength is greater than 5MPa, folding strength is greater than 8MPa, far above current standards.
