The present invention is a calcium silicate plate (commonly known as a silicate plate).
This invention relates to a synthetic resin emulsion for use as a sealer for firmly adhering sheets to surfaces. In order to make quartz plates, one of the manufacturing methods is the papermaking method, which uses silicic acid raw materials such as silica sand and diatomaceous earth, which are the raw materials for quartz plates, and calcareous raw materials such as limestone (slaked lime). , a slurry reinforced with inorganic fibers such as asbestos is rolled up with rolls like a paper machine makes paper, usually for 5 to 6 minutes.
Layer it up, cut it to the specified size, and heat it at 180℃.
It is obtained by curing it in an autoclave at 10 atm for 10 hours. The papermaking method is suitable for manufacturing thin products with a thickness of 4 to 10 mm. In addition, there is a press method for manufacturing thick plates. The mechanical board obtained in this way is an excellent noncombustible building material that is lightweight, has high strength, high dimensional stability, high heat insulation properties, can be cut with a saw, and repels termites and rats. As a result, demand for it as an interior material for houses, buildings, condominiums, etc. has increased rapidly in recent years. However, like ALC boards (autoclaved lightweight concrete boards), mechanical boards, which are excellent building materials, have strong water absorption properties, so in order to be used as exterior materials, they must be treated with waterproofing such as pasting a waterproof sheet. There must be. In the case of ALC boards, the surface is rough and has countless pores, and the peel strength of the surface is also strong to a certain extent, so it is possible to attach a waterproof sheet such as a rubber sheet with adhesive, or use a self-adhesive asphalt sheet as is. Waterproofing can be applied by pasting the sheet, but the surface of the stent is dense and powdery, so even if such a waterproof sheet is pasted, the adhesive interface will turn into powder and peel off. This also poses a problem when used as an interior material. In other words, interior materials need to be decorated to match the interior atmosphere. For this purpose, attempts have been made to attach decorative sheets such as wall coverings made of cloth, paper, plastic, etc. to the surface of the mechanical board.
After all, the interface becomes powdered and peels off. Another possible cosmetic method is to paint with paint, but this also causes uneven absorption due to the water absorption of the mechanical board, making it impossible to paint beautifully.
It is difficult to replace the decoration by pasting decorative sheets with painting. The inventors of the present invention have conducted various studies regarding this problem, and have found that after applying a specific acrylic emulsion as a sealer and drying it, a self-adhesive sheet such as an asphalt sheet can be made without using an adhesive. We discovered that when non-self-adhesive sheets are attached using an adhesive, the sheets adhere firmly and there is no phenomenon of the interface becoming powdered and peeling off, making it fully usable for practical use, and thus completing the present invention. . That is, the present invention includes one or more selected from esters of saturated alcohols having 1 to 20 carbon atoms and acrylic acid or methacrylic acid, and optionally vinyl esters, α, β unsaturated carboxylic acids, monovinyl monomers, and One or more crosslinkable monomers are emulsion-polymerized using a large amount of emulsifier, and the particle size obtained without neutralizing with an alkali agent is 0.02~
This is a synthetic resin emulsion for use as a sealer for attaching sheets to calcium silicate plates made of 0.2 micron acrylic synthetic resin emulsion. Examples of sheets that can be attached by the method of the present invention include asphalt sheets, natural or synthetic rubber sheets, plastic sheets such as polyethylene, polypropylene, ethylene-propylene-dien terpolymer (EPT), polyester, polyacrylic, polyvinyl chloride, and cloth. , paper sheets, etc. These sheets are usually attached using an adhesive, but there are also self-adhesive sheets such as asphalt sheets that can be attached without using an adhesive. In the present invention, the synthetic resin emulsion for sealer to be applied to the mechanical board in advance includes:
Methyl acrylate or methyl methacrylate [hereinafter referred to as methyl (meth)acrylate], ethyl (meth)acrylate, butyl (meth)acrylate, 2-ethylhexyl (meth)
Acrylates, (meth)acrylates such as cyclohexyl (meth)acrylate, and vinyl esters such as vinyl acetate, branched higher fatty acid vinyl esters, (meth)
α, such as acrylic acid, crotonic acid, itaconic acid, etc.
Copolymerized with β-unsaturated carboxylic acid, monovinyl monomers such as ethylene, styrene, and vinyl chloride, and 10% by weight or less of crosslinkable monomers such as N-methylolacrylamide, glycidyl methacrylate, and divinylbenzene, with a particle size of 0.02 ~0.2 micron aqueous emulsion is used. Particularly suitable is a (meth)acrylate polymer emulsion copolymerized with 20% by weight or less of an unsaturated carboxylic acid. Vinyl acetate is 40% as a copolymerization component.
It is okay to use less than 40% by weight.
If used in excess of this amount, the permeability will be poor and it is inappropriate. In particular, those using polyvinyl alcohol as an emulsifier are undesirable because their particle size is large and they are difficult to penetrate, causing interfacial peeling. The larger the particle size of the emulsion, the worse the permeability, so the smaller the better, and the particle size should not exceed 0.2 microns at most. Emulsions with a particle size of 0.1 micron or less are called hydrosols and are particularly preferred. Hydrosol can be produced by polymerization using a large amount of surfactant. When the emulsion copolymer contains carboxyl groups, a hydrosol can be obtained by neutralizing the carboxyl groups with an alkaline agent, but the hydrosol obtained in this way has poor water resistance, so the present invention It cannot be used as an emulsion for sealers. In the present invention, the coating amount of this specific acrylic synthetic resin emulsion is not particularly specified, but it is suitably in the range of 10 g/m 2 to 300 g/m 2 in terms of solid content. To adhere a sheet using the synthetic resin emulsion for a sealer of the present invention, first apply the acrylic synthetic resin emulsion for a sealer of the present invention to the surface of a medical board, and after drying, apply the self-adhesive sheet. The sheets can be attached by themselves, and other sheets can be attached using adhesive. As the adhesive, a rubber contact type adhesive or a synthetic resin emulsion type adhesive is used. When using an emulsion type adhesive, it is best to apply it after it has dried to a transparent level or higher during the second half of application. It is believed that the effect of the acrylic synthetic resin emulsion for sealers of the present invention is that it penetrates into the inside of the silicate plate from the surface to increase surface strength and also improve adhesiveness. If the acrylic synthetic resin emulsion for sealer of the present invention is used, it can be used as a wall covering material after attaching a mechanical board to the outer wall of a building and then attaching a waterproof sheet, or attaching the mechanical board to an inner wall as an interior material. However, it is preferable to use the acrylic synthetic resin emulsion for sealer of the present invention in a factory to prepare a processed diaphragm plate with a sheet such as a waterproof sheet attached, and then to use it on-site. It is best to attach it to the interior and exterior walls. Next, the present invention will be explained with reference to Examples and Comparative Examples. Example 1 65 parts by weight of butyl acrylate, 35 parts by weight of styrene, and 3 parts by weight of methacrylic acid were emulsion polymerized using 2 parts by weight of polyoxyethylene nonyl phenyl ether and 8 parts by weight of lauryl sulfonate as emulsifiers to obtain a particle size of 0.03 micron. A sealer emulsion for attaching sheets to mechanical boards. Examples 2 to 7 Emulsions for sealers for attaching sheets to mechanical boards were emulsion polymerized using the monomers and emulsifiers listed in Table 1 according to Example 1. Comparative Examples 1 to 6 Comparative emulsions were emulsion polymerized according to Example 1 using the monomers and emulsifiers listed in Table 1. Comparative test Examples 1 to 7 were applied to a 10 cm x 20 cm mechanical board (Hishiratsuk No. 100 manufactured by Mitsubishi Cement Kenzai Co., Ltd.) with a thickness of 10 mm.
The obtained sealer emulsion and the emulsions obtained in Comparative Examples 1 to 6 were applied as a sealer at a rate of 50 g/m 2 , and after drying, the sheets shown in Table 1 were attached, and after curing for a day and night, the peel strength of each (25 mm , 180° tear) was measured. The comparative test results are shown in Table 1. Comparative Examples 7-8 This is a case where a synthetic resin emulsion sealer is not used.
