The present invention relates to a method for coloring inorganic board materials. In general, inorganic board materials have an achromatic background color ranging from dark gray to white, and are often colored because they lack aesthetic appeal. As a means of coloring, there is painting with emulsion paint, etc. However, coloring by painting has the advantage of being able to cover the surface of the water-absorbing inorganic board with a coating film and impart water resistance, but it There is an inherent difficulty in peeling off the film, which poses a problem in long-term service life. On the other hand, various methods have been proposed and implemented in which coloring pigments are mixed into the surface layer of the inorganic board material or the surface layer of the inorganic board material to color the board material itself, but when this method is used, the material itself is relatively expensive. It is necessary to add large amounts of coloring pigments, especially the former, as the plate material becomes too expensive and is not suitable.In addition, a large amount of calcium carbonate is used as an extender or extender pigment for these colorings. As a result, frost damage resistance and water permeability resistance deteriorate,
Moreover, it has the disadvantage of low strength, and furthermore,
When asbestos is used as reinforcing fibers, there is a problem in that the asbestos may be scattered due to future surface weathering, which is inconvenient in terms of pollution prevention. In view of the above-mentioned problems, this invention solves the problems caused by painting by coloring the material itself, and at the same time solves the problems such as frost damage resistance, water permeability resistance, strength, etc. when using these pigments. This was done with the aim of obtaining a method for coloring inorganic board materials that can also eliminate the
Cement, aggregate, reinforcing fibers, etc. are mixed with water to form an inorganic base plate of a predetermined thickness, and then a mixture of cement and silica at a mixing ratio of 1:08 to 1.2 and a total amount of cement and silica is placed on this base plate. 205-220 parts by weight, polypropylene fiber 0.01-5.0 parts by weight, color pigment 0.1
A colored inorganic raw material made by mixing ~20.0 parts by weight is supplied, water necessary for curing is sprayed and supplied, and then compressed to form a surface colored layer. After primary curing in natural curing, high temperature and high pressure steam curing. It is characterized in that it is finally cured by doing this. Next, a dry manufacturing method will be described using this invention as an example, but it goes without saying that a paper manufacturing method may also be used. The drawing is a side view of the apparatus used to carry out the method of the invention. The illustrated example uses a so-called dry manufacturing method, but it goes without saying that other manufacturing methods, such as a papermaking method, may also be used. In the method for coloring inorganic plate materials of the present invention, cement, aggregate,
Dry raw material 2 mixed with reinforcing fiber etc. is transferred to hopper 2A.
3, sprinkled with water 3, compressed with roll 4,
An inorganic base plate 20 of a predetermined thickness is formed, and then a mixture ratio of cement and silica is 1:1 on this base plate 20.
0.8 to 1.2 and total amount of cement and silica 205
A colored inorganic raw material 5 consisting of a mixture of ~220 parts by weight, 0.01 to 5.0 parts by weight of polypropylene fibers, and 0.1 to 20.0 parts by weight of a colored pigment is supplied from a hopper 5A, and after being sprayed and supplied with water 6 necessary for curing, it is rolled. 7 to form a surface colored layer 25, this is taken out from the conveyor 1, and after primary curing in natural curing, it is finally cured by high temperature and high pressure steam curing in an autoclave 8. There is. In the above, the material for the inorganic base plate 20 may be any compound normally used for cement and aggregate reinforcing fibers, and any reinforcing fibers such as glass fiber or asbestos may be used. Alternatively, these reinforcing fibers may be omitted altogether. Furthermore, in the colored inorganic raw material 5 for surface coloring, if the cement and silica content is less than 205 parts by weight, the product strength will be insufficient, and if it is more than 220 parts by weight, the coloring effect will be reduced due to the relationship with the pigment. The reason why the mixing ratio of cement and silica is 1:0.8 to 1.2 is to promote the silica reaction of cement and increase the bonding strength of the matrix. The above silica content includes silica sand,
Finely divided silica sand is used, and from the viewpoint of improving reactivity, it is preferable to use finely divided silica sand having a large Blaine value. Also,
Polypropylene fibers are used to adjust the fluidity of coloring raw materials,
and the bending strength of the inorganic original plate before primary curing,
It is especially formulated to prevent the formation of hair cracks, and during high-temperature, high-pressure steam curing, it is melted by heat and adheres to the inner surface of the cavity where the fibers were present in a film form, thereby demonstrating the water resistance of the surface colored layer. The reason why the amount is 0.01 to 5 parts by weight is that if it is less than 0.01 parts by weight, the above effects cannot be obtained, and if it is more than 5 parts by weight, the fluidity of the colored inorganic raw material will deteriorate and uniform layered dispersion will not be possible. This is also because the strength of the colored layer decreases significantly after curing in high-temperature, high-pressure steam. The polypropylene fibers are most preferably in the form of fibrillated pulp, but there are no particular disadvantages as long as they have a thickness of 0.5 to 15 deniers and a length of 0.5 to 3 mm. Various types of pigments are used, including red pepper, but the reason why the amount added is 0.1 to 20 parts by weight is because if it is less than 0.1 part by weight, sufficient coloring cannot be achieved. This is because, although increasing the amount does not change much in terms of coloring, it is economically wasteful because pigments are expensive. In addition, the primary curing is carried out at room temperature for 2 to 3 days, and the high temperature and high pressure steam curing in an autoclave is
180℃ due to the relationship with the melting point of polypropylene fibers
It is carried out at a temperature higher than that. Incidentally, after the primary curing and before the high temperature and high pressure curing, the surface may be coated with an emulsion paint. As explained above, in this invention, a colored inorganic raw material layer is provided on an inorganic base plate, and this is integrally molded. Therefore, pigments, etc. need only be added to the colored surface layer, and the amount of pigment used can be reduced. In addition to having the advantage of saving money, the surface colored layer contains polypropylene fibers, which gives the board bending strength during the inorganic board forming process.
Inorganic boards make it easier to handle the board when uncured, and after curing, it melts and adheres to the inner surface of the cavity made of fibers in the matrix of the surface layer, thereby imparting water absorption resistance. It has improved frost damage resistance and water absorption resistance, and at least the colored surface layer does not contain any asbestos, so there is no risk of pollution even if the surface weathers due to long-term use. It has various advantages. Incidentally, freeze-thaw tests and water permeability tests were conducted on an inorganic board material whose surface was colored according to the present invention and an inorganic board material having an inorganic colored surface layer that does not contain polypropylene fibers, and the following results were obtained. (b) Sample sample Portland cement as cement and Blaine value as silica on an inorganic base plate with a thickness of 4 mm made by mixing cement, aggregate, and asbestos.
Two types of finely divided silica sand of 5,000 g/cm 2 and 12,000 g/cm 2 were used at a mixing ratio of 1:1, and 230 parts by weight of this mixture, 1 part by weight of polypropylene fibers,
A surface layer with a thickness of 1 mm is formed by a dry method using an inorganic raw material containing 10 parts by weight of pigment, and after natural curing for 3 days, it is immediately steamed in an autoclave at 190°C and 6 atm high temperature and high pressure for 9 hours. After curing, an inorganic board with a thickness of 5 mm was obtained. (b) Comparative example The total amount of cement and silica made of the same material as in the example was 100 parts by weight as the surface layer inorganic raw material,
Calcium carbonate 95 parts by weight, asbestos 37 parts by weight, pigment
An inorganic plate material was obtained in which the amount was 12 parts by weight and the other parts were the same as the sample. (a) One-dimensional freeze-thaw test Samples were heated from +20°C to -20°C every 6 hours.
A one-dimensional freeze-thaw test was carried out by placing the sample in a room where the temperature was changed to a temperature of 0.degree. The evaluation points are 5 points for "no change," 4 points for "little change," 3 points for "change in progress," and 3 points for "major change."
``The change was very large'' was given a 1 point.
