Ceramic tile, marble jointing material
Technical field
The invention belongs to building material technical field, be specifically related to a kind of ceramic tile, marble jointing material.
Background technology
Behind intact metope of ceramic tile, marble or grouan paving or ground, all must carry out filleting handles, this has not only strengthened finishing effect, make between fragment of brick and the fragment of brick lines orderly, color is even, full, shows very harmonious decorative effect, and after the slit tamped processing, rainwater etc. are difficult for entering in the adhesive layer between ceramic tile, marble and metope, the ground, have both avoided the destruction of tack coat, also can prevent preferably wall, sweat.
Past, ceramic tile, after marble or the grouan paving, the workman generally adopts earlier that paving face is wetting, wipe the method for stitching with mop after spreading dry cement again, with ceramic tile, slit between marble blocks is filled up, adopt this method, on the one hand to ceramic tile, very big pollution is caused on marble and grouan surface, influences decorative effect, on the other hand, sometimes be rubbed into that cement between the slit still does, can not get the required water of aquation, may split away off very soon, and the partial water gray scale is big sometimes, intensity is low behind the hydration and hardening, with ceramic tile, marble side viscosifying power is poor, also is easy to soon come off.For the situation of gap paving, promptly also there is the practice that adopts common sand-cement slurry to carry out filleting (jointing) in the slit between ceramic tile or the marble than the situation of broad.As everyone knows, common sand-cement slurry is dull coloring not only, and cohesive strength is low, contract with dry rate is big, and the time one is of a specified duration, also be very easy to come off, if bond quality is bad between ceramic tile, marble and the basic unit, very easy cause metope, sweat harm.
Along with the raising of living standards of the people, more and more higher to the requirement of the quality of buildings and decorative effect, market is called the cohesive strength height, is shunk little, rich color, can better satisfy the jointing material of modern's esthetic requirement.
Summary of the invention
The object of the present invention is to provide a kind of ceramic tile, marble jointing material.
Ceramic tile, marble jointing material that the present invention proposes, be made up of white portland cement or ordinary Portland cement, titanium dioxide, quartz sand, aluminium sulfate expanding agent, Mierocrystalline cellulose, polyvinyl acetate (PVA) (Vinnaps RE5028) latex powder and pigment, the weight ratio of each component is:
White portland cement or ordinary Portland cement 100
Titanium dioxide 0-6
10-30 order quartz sand 70-140
100-140 order quartz sand 35-73
Aluminium sulfate expanding agent 1-9
Mierocrystalline cellulose 0.35-0.8
Polyvinyl acetate (PVA) latex powder 0.5-4.5
Pigment 0-14
The preferable weight ratio of each component is:
White portland cement or ordinary Portland cement 100
Titanium dioxide 0-5
10-30 order quartz sand 86-135
100-140 order quartz sand 40-68
Aluminium sulfate expanding agent 2-8
Mierocrystalline cellulose 0.40-0.75
Polyvinyl acetate (PVA) latex powder 1.5-4.0
Pigment 0-10
Preparation method of the present invention is: by aforementioned each part by weight weighing each component, mix by physical mechanical, promptly obtain this product.
Among the present invention, white portland cement or ordinary Portland cement be as inorganic coagulation material, can with mixing water generation hydration reaction, produce hydrated product, sclerosis back produces intensity, and can and basic unit's mortar and ceramic tile, marble lateral parts between produce snap-in force, form whole.When preparation white or light jointing material, should use white portland cement, and when the dark jointing material of preparation, should use ordinary Portland cement.Titanium dioxide has extremely strong whitening effect, and can eliminate because little yellow of aluminium sulfate expanding agent, quartz sand etc. itself to the influence of jointing material color, obtains satisfied ultrawhite color effect.Grade and two kinds of quartz sands of thin level are high-strength gathering materials, and wherein thin quartz sand is filled in the space that stays after thick quartz sand is piled up, and forms solid skeleton, and its space is further filled by cement slurry, bonds together and form integral body.The purpose that aluminium sulfate expanding agent mixes is and can reacts with hydrated product in cement hydration process, produce the swelling property product of some amount, the dry caused contraction of compensation water mud, make in jointing material sclerosis, the drying process, volume does not change substantially, can not crack even come off.Mierocrystalline cellulose is as the water-keeping thickening component, its role is to can be in cement slurry swelling, produce the bridging effect, and cement granules and titanium dioxide particle linked together by the molecular adsorption effect, avoid particles settling and separate; When slurry flows, guarantee that slurry becomes integral body, can't produce excreting water phenomenon; Cellulosic effect is also to prevent that moisture is absorbed or excessive vaporization by basic unit in the jointing material, thereby plays well in the maintenance effect, after product being colluded be applied in the slit, and produces strong cohesive action between basic unit and the ceramic tile side.The polyvinyl acetate (PVA) latex powder becomes emulsion after meeting water, can not only increase the stability of slurry, and in the slurry process of setting, the dry gradually dehydration of emulsion, the Vinyl Acetate Copolymer ester molecule interconnects, form one deck macromolecule membranous layer, strengthen the toughness and the shock resistance of this product, improve this product and basic unit and the lateral cohesive strength of ceramic tile.Pigment can adopt multiple, and available multiple pigment is used, and giving product of the present invention various colors, thereby meets design requirement.
The present invention is white or colored dry powder material (pigment variety of looking adding is different), during use, water reconciles into paste, and suitable amount of water is the 16%-30% of jointing material weight, and concrete amount of water is determined by test according to required denseness that slurry is reached and application property.
The present invention is nontoxic, tasteless, pollution-free, non-corrosiveness, and it is little that filleting is handled after strain, do not come off, and can strengthen ornamentally, improves metope, ground integral waterproofing, and guarantees and increase the service life.The present invention is easy to use, as long as stir and can construct according to recommending water consumption directly to add water at the scene.The present invention is applicable to the filleting after ceramic wall and floor bricks, marble and the grouan paving is handled.
