Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resin concrete pseudostone tile using natural crushed stone as an aggregate and a thermosetting synthetic resin as a binder.

Flyer tiles, which are made by bonding natural crushed stone aggregates such as marble, rock, granite, etc. with cement and forming them into plates, are widely used on the floors, walls, and pillars of buildings. However, when this type of leaflet tile is used outdoors in rain and dew, or indoors in humid conditions, it easily absorbs water from the cement part, and the crushed stone aggregate and cement Water permeates or absorbs water from the interface, resulting in a poor finished surface.
It has many drawbacks, such as losing its luster and becoming cloudy, and efflorescence, which limits the places where it can be used.
If 5F strength was insufficient when used as a finishing material for sidewalks.

The present invention was completed with the aim of creating a resin concrete pseudostone tile developed in view of the current situation. 7-10tts

The natural crushed stone bone used in the present invention: The phase is obtained by crushing relatively hard rocks such as marble, limestone, limestone, granite, and turquoise, and crushing it into particles as specified in J18Z, lza0/. Tasai 4th Flui □ Tsuso 7~/Qyrt's:

m is preferably in the range, and the appropriate amount is approximately 200 to 3jO parts by weight per 700 parts by weight of the binder phase. In addition, by adding an appropriate amount of a low-shrinkage synthetic resin of the same series and quality to the epoxy resin and polyester/I/resin PSLTI thermosetting synthetic resin as the binder phase and blending it, dimensional stability and cure shrinkage can be improved.

It is effective in alleviating Jl□response. By the way, trees
Invented by Ming, it is necessary to impart high strength, especially abrasion and impact resistance, to the product so that it maintains its beautiful appearance for a long period of time. For this purpose, the surface and surface layer of the product must be hardened. Therefore, it is necessary to appropriately select the grain size and blending ratio of the natural crushed stone bone phase to give the surface layer a desirable structure.
The most desirable performance cannot be obtained when the surface aggregate pebble ratio is 60 to 0% and the natural crushed stone aggregate ratio of grain size 7 to 70 is 3j% or less. To achieve these values, it is important to manage product manufacturing needs. In addition, as mentioned above, the moisture content of natural crushed stone bone phase is usually 0.5~/,
, 22%, but if you use a product with a high moisture content as it is, it may cause problems during molding! Do not reduce the water content to 0 or 0, as this may cause blistering, air bubbles, and clouding of the surface after surface polishing.
It is preferable to use it after drying so that the Ir content is less than 1% and Ir1005%. Furthermore, this natural crushed stone aggregate and the binder epoxy resin and polynisder resin increase their binding affinity and form a chemical bond. It is preferable to surface-treat the surface with a methacrylate chromic loride agent □ to improve the properties of the methacrylate chromic loride agent □.

It should be noted that it is sufficient for the methacrylate-1/RIF + Mitsu-1 1 chloride agent to be attached to the crushed stone bone H at a ratio of 005 to 07% of the natural crushed bone phase in terms of senior ministers. How to do it is □).

Sea method 2 Any method such as the immersion method may be used.
! Iv1.・First, the sieved natural crushed stone aggregate is heated in an electric drying oven.
Otsu 0'C/, dried under the conditions of 2 hours, but under reduced pressure θj~
Dry by an appropriate method such as drying in a chamber at 0°C or 0°C. Next, three types of natural crushed stone aggregates having the particle size as described above, a filler, and a thermosetting synthetic resin binder are weighed out at a predetermined ratio using a hoe, and thoroughly mixed using a mixing agitator. If necessary, add a percentage of natural crushed stone bone + J'K methacrylate chromitase chloride agent in advance, and then feed the thoroughly mixed mixture to the heated molded gold powder.
When a pipe range of 9 □ is given to the mold, the natural crushed stone bone phase in the compound that has a higher specific gravity and 11 grains, that is, a larger shape, gathers more quickly to the bottom of the mold due to the difference in weight. The bottom of the mold is the surface of the product, where coarse and fine particles are inserted and dispersed appropriately to form a surface layer. The preferred arrangement of coarse and fine grains is determined experimentally.
The product is molded and heat-cured according to the conditions of the equipment in which the preferred configuration is obtained. In addition, when using a molding method that does not give pipeage, the bottom of the mold or the top surface i? A compound having a predetermined particle size and composition is fed into the area that will become the iI layer, and then after applying light pressure with the upper die, the compound that will form the back iri+F'M is supplied to the area that will become the iI layer. Immediately add heat and cure. Pressurized and heated hardening is performed on the high pressure side KA [with a pressurized machine for a predetermined period of 7 ゛ under +].
manufacture products. Next, in a 1-ill polishing process, the surface of the molded product is polished in three stages: rough polishing, medium polishing, and main polishing to create a finished product. If necessary, a puff finish may be applied using gloss powder, or waxing may be applied.

As is clear from the above description, the present invention has succeeded in manufacturing tiles that have excellent mechanical strength and excellent water resistance, and compared to conventional flyer tiles, the present invention has been successful in producing tiles with excellent mechanical strength and excellent water resistance. ■It has more than 3.6 times the strength under load, and the impact strength is more than 5 times as many times as the weight falls before cracking compared to leaflet tiles.
The floor does not crack or crack even when laid on outdoor walkways or arcades with military eaves, making it suitable for use in humid environments that have traditionally been considered unusable. Coupled with the advantages of inato, which does not cause defects such as fogging or efflorescence even when used in places exposed to steam or steam, such as caves containing corrosion products, it has an excellent aesthetic appearance. The contribution made to the development of the industry as a resin concrete pseudostone tile is extremely significant.
