Abstract
The concrete roof tile is prepared from the following raw materials in percentage by weight: 25-35% of cement, 35-45% of yellow sand and 15-45% of coal cinder. The manufacturing method comprises the following steps: firstly, cement, yellow sand and cinder are measured, then water is added into the mixture and the mixture is sent into a stirrer, the mixture is extruded and formed in a die cavity after being stirred uniformly, and then the finished product is obtained after glazing, curing and demoulding. The invention has the advantages of reasonable resource utilization, effective improvement of the compactness and the mechanical strength of the finished product, convenient construction and long service life because more coal cinder is added.
Description
The present invention relates to a kind of manufacture method of concrete roof tile, belonging to cement, cinder etc. is the concrete tile and the manufacturing technology field of main raw material.
Continue to use Qin brick and Han tile in several thousand, for the social progress of China have ever made indelible contribution, but traditional brick and tile are main raw material with the clay mostly, form through high temperature sintering, and not only because of nibbling the serious waste land resources of ploughing in a large number, and energy consumption is higher.And available coagulation is a main raw material with cement, yellow sand for native watt, though can economize the land resource, raw materials cost is higher.
The purpose of this invention is to provide a kind of is main raw material with cement, yellow sand, cinder etc., and manufacturing cost is lower, can reasonable energy utilization, effectively improve the manufacture method of the concrete roof tile of folding strength.
The present invention is the manufacture method of concrete roof tile, its raw material comprises cement, yellow sand etc., it is characterized in that also comprising simultaneously cinder, the weight percent of above-mentioned each component is respectively: cement 25～35%, yellow sand 35～45%, cinder 15～45%, its manufacture method is: send adding water after cement, yellow sand, the cinder metering into stirrer together earlier, back extrusion molding in die cavity, demoulding finished product after glazing, maintenance then stir.
Also can add binding agent in the raw material of described concrete roof tile, its addition can be 8～30% of cement weight.Described binding agent can be polyvinyl alcohol or unsaturated polyester, Resins, epoxy etc.
Described cinder can carry out pulverization process before mixed, the cinder fineness after the pulverization process can be 1.5～0.5mm.
Also can carry out surface colour after the described extrusion molding and handle, its painted operation can be the colouring matter that will be formed by white cement and pigment, water and is sprayed at the concrete roof tile surface after stirring.
Described extrusion molding can be adopted the cold tire moulding of half-dried extruding, can improve the degree of compactness of product.
Also can on shaping mould, apply mold oil for building before the described extrusion molding.
The present invention is owing to added more cinder, both rationally utilized resource, turn waste into wealth, significantly reduce cement consumption, thereby reduction raw materials cost, can effectively improve the degree of compactness and the physical strength of finished product again, and the surface colour of being carried out after the extrusion molding is handled, also can give the concrete roof tile multicolour, realized attractive in appearance preferably and perfect adaptation performance, concrete roof tile of the present invention has lovely luster, good looking appearance, the intensity height, anti-leakage, weathering resistance, easy construction, outstanding advantage such as long service life can be widely used in building in the style of the ancients and residential houses, can obviously improve the grade of buildings.
Accompanying drawing has provided technological process of production figure of the present invention.
Below in conjunction with embodiment the present invention is further described.
The embodiments of the invention prescription is (by weight percentage)
Cement: 28～32%
Yellow sand: 38～42%
Cinder: 25～35%
Polyvinyl alcohol: 10～15% of cement weight
With add after the metering of above-mentioned main raw material water by technical process shown in the accompanying drawing produce the concrete roof tile finished product.
The present invention is through practical application and check, its monolithic folding strength can 〉=2300N,
