Description
Technical field
The invention discloses a kind of preparation methods of energy-saving floor tile, belong to construction material preparing technical field.
Background technology
A kind of floor decorative material of floor tile, also known as floor tile.It is fired with clay.Specification is a variety of.Matter heavily fortified point, unit weight
Small, pressure resistance is wear-resisting, can be moisture-proof.Some has decoration function through glazing treatment.It is chiefly used in the ground of public building and civil buildings
And flooring.The kind of floor tile has all-body tile, glazed tile, entire body polishing brick and tile, pattern permeating tile, oozes colored polished bricks etc., these floors
Brick is not all anti-skidding, especially there is old man and child in family, has to do anti-skidding test in purchase, in order to avoid go out to ask
Topic.Common floor tile has：Full-glazed tile, vitrified tile, polished bricks, matt brick, glazed tile, stamp brick, anti-skid brick, extraordinary acid-proof
Brick.
Floor is the indispensable ornament materials of modern house, can be divided into timber floor, bamboo flooring, plastic floor, compoundly
Plate etc., timber floor generally layer of transparent paint on the surface thereof, to show the lines of wood, meanwhile, so that timber floor is become smooth,
The disadvantage is that can slowly ooze out, be detrimental to health containing chemical substances such as formaldehyde in the colored varnish, not only price is high for plastic floor,
The gas being pernicious to people also is easy tod produce when temperature is high, composite floor board generally uses gluing, has containing formaldehyde etc. in glue
Evil substance, can slowly release and be detrimental to health.In numerous floor decorative materials, floor tile becomes the head of consumer
Choosing.
It is key link that current China, which promotes building energy conservation, Development of Green Building, for example according to local climatic characteristic, is adopted
With advanced Building technology and material, system adjustment, maximum limit are carried out to natural causes such as the sound, light, heat that act on building
Degree ground reduces the energy consumption of building and heating and refrigeration.With the fast development of society, worldwide energy shortage problem day is increasingly
Play, sustainable development view are more rooted in the hearts of the people, it is energy saving oneself by China and global common concern, building is to use energy
Rich and influential family, there is nearly 30% energy consumption in the whole world on building, in China, building energy consumption oneself be more than national total energy consumption
1/4, but build, the energy saving temperature controlling temperature poor performance of special floor tile low to the utilization ratio of the energy, and sintering production
