Description
【考案の詳細な説明】 本考案はセメント系屋根材に関するものである。[Detailed explanation of the idea] The present invention relates to cement-based roofing materials.
セメント系板材を製造する場合、セメントに珪砂並びに
細骨材を混合した原料の水添加物を板状に成形し、この
成形物、すなわち生原板を高温、高圧の飽和水蒸気でオ
ートクレイプ養生することが知られている。When manufacturing cement-based board materials, a water additive mixture of cement, silica sand, and fine aggregate is formed into a board shape, and this molded product, that is, the raw board, is autoclaved and cured in high-temperature, high-pressure saturated steam. It has been known.
か・る製造法によれば、養生が強制的に行われるため、
生産能率を向上させ得るといった利点がある他、珪砂が
セメント中の石灰質と反応して、強靭な結晶であるトバ
モライト若しくはゾノライトを生成するので、板材の強
度向上にも有利である。According to the Karu production method, curing is forced, so
In addition to the advantage of improving production efficiency, silica sand reacts with the limestone in cement to produce tobermorite or zonolite, which is a strong crystal, which is also advantageous in improving the strength of the board.
か・るセメント系板材を屋根材として使用するには、吸
水、乾燥の繰返しによる屋根材の変形成いは、屋根材中
の遊離石灰が吸水下のもとて表面に滲出し、これが空気
中の炭酸ガスと反応して炭酸カルシウムを生成する現象
、すなわち白華現象を防止する必要があり、このため、
板材に充分な防水性を賦与することが要求される。When using cement-based board materials as roofing materials, the roofing material may deform due to repeated water absorption and drying, or the free lime in the roofing material may ooze out to the surface due to water absorption, and this may be absorbed into the air. It is necessary to prevent the phenomenon of reacting with carbon dioxide gas to produce calcium carbonate, that is, the efflorescence phenomenon.
It is required to provide sufficient waterproofness to the board material.
上記セメント系板材に防水性を賦与する一方法として、
上記原料中に撥水剤、例えばステアリン酸金属塩を混入
することが考えられるが、この場合は、撥水剤がセメン
トの水和反応乃至は珪酸カルシウム反応を阻害するから
、板材の強度低下が懸念される。As a method of imparting waterproofness to the above cement-based board material,
It is possible to mix a water repellent, such as a metal stearate, into the above raw materials, but in this case, the water repellent inhibits the hydration reaction or calcium silicate reaction of cement, resulting in a decrease in the strength of the board. There are concerns.
また、上記した生原板の表面に、プラスチック塗料を塗
布し、上記のオートクレイプ養生時にこのプラスチック
塗料を焼付け、製膜する方法も知られている。Also known is a method of applying a plastic paint to the surface of the raw original plate described above and baking this plastic paint during the autoclave curing to form a film.
この方法においては、オートクレイプ養生時の加熱を、
プラスチックの製膜に利用しており、特別の焼付は製膜
工程を必要としないので、工程的に有利である。In this method, heating during autoclave curing is
It is used to form plastic films, and it is advantageous in terms of process since no special baking is required in the film forming process.
しかしながら、この場合は、板材の全面に、防水膜を設
けることは無理である。However, in this case, it is impossible to provide a waterproof membrane over the entire surface of the board.
すなわち、板材の全面にプラスチック塗料を塗布すると
、オートクレイプ養生時、原板中がらの水分の蒸気がプ
ラスチック塗膜のために板材中にとじこめられ、この蒸
気圧力が急激に上昇して、逐には塗膜に多数のピンホー
ルが形成されるに至るといった不都合が避けられない。In other words, when plastic paint is applied to the entire surface of a board, during autoclave curing, the moisture vapor in the original board is trapped inside the board by the plastic coating, and the pressure of this vapor increases rapidly, resulting in Inconveniences such as formation of numerous pinholes in the coating film cannot be avoided.
本考案に係るセメント系屋根材は上述の点に鑑みて案出
されたものであり、撥水剤を含有せるセメント系着色層
がセメント系板状基材部の表面に設けられ、該基材部の
周囲側面並びに裏面にはプラスチック塗膜が設けられて
おり、全体が高温高圧蒸気養生により養生硬化されて成
ることを特徴とする構成である。The cement-based roofing material according to the present invention was devised in view of the above-mentioned points, and a cement-based colored layer containing a water repellent is provided on the surface of a cement-based plate-like base material. A plastic coating is provided on the peripheral side surfaces and the back surface of the part, and the entire part is cured and hardened by high-temperature and high-pressure steam curing.
以下、図面により本考案を説明する。The present invention will be explained below with reference to the drawings.
図において、1はセメント系板状基材部であり、セメン
I・、珪砂、細骨材の混合原料が水和反応によって硬化
された組織を有する。In the figure, reference numeral 1 denotes a cement-based plate-like base material part, which has a structure in which a mixed raw material of cement I, silica sand, and fine aggregate is hardened by a hydration reaction.
2は撥水剤、例えばステアリン酸カルシウムを含有せる
セメント系の着色層であり、基材1の表面に水和反応に
よって一体的に結合されている。2 is a cement-based colored layer containing a water repellent such as calcium stearate, and is integrally bonded to the surface of the base material 1 by a hydration reaction.
このセメント系着色材料には、セメントに珪砂、顔料、
ステアリン酸カルシウムを配合したものが用いられる。This cement-based coloring material contains cement, silica sand, pigment,
A compound containing calcium stearate is used.
3は基材1の周囲側面並びに裏面に焼付けられたプラス
チック塗膜であり、例えばアクリル樹脂が用いられる。Reference numeral 3 designates a plastic coating film baked onto the peripheral side surface and back surface of the base material 1, and is made of, for example, acrylic resin.
上記屋根材を製造するには、セメント、珪砂、細骨材の
混合原料の水添加物を板状に成形し、この成形物、すな

テアリン酸カルシウム、並びに水を添加したセメント系
着色材を塗布し、また板状上基材の周囲側面並びに裏面
に、アクリル樹脂エマルジョンを塗布し、而るのちに、
オートクレイプによって養生処理する。To manufacture the above roofing material, a water additive of a mixed raw material of cement, silica sand, and fine aggregate is formed into a plate shape, and a mixture of cement, silica sand, and pigment is applied to the surface of the formed product, that is, the plate-shaped upper base material. , calcium stearate, and a cement-based coloring agent added with water are applied, and an acrylic resin emulsion is applied to the peripheral side and back surface of the plate-shaped upper substrate, and then,
Curing treatment is performed by autoclape.
この場合、板状基板は、セメントの水和反応並びに珪砂

化され、セメント系着色材層も同上の反応によって硬化
されると共に、着色材層と板状基板との境界が同上の反
応によって強固に結合される。In this case, the plate-shaped substrate is hardened by the hydration reaction of the cement and the calcium silicate reaction between the silica sand and the lime content in the cement, and the cement-based coloring material layer is also hardened by the same reaction, and the coloring material layer and the plate-shaped substrate are hardened by the same reaction. The boundary with the substrate is firmly bonded by the above reaction.
他方、プラスチック塗料は、オートクレイプ養生中、そ
の熱によって、焼付は製膜される。On the other hand, plastic paints are baked into a film due to the heat during autoclave curing.
養生中での板状基材からの水分の蒸気はセメント系着色
材層からとどこおりなく行われ得、プラスチック塗膜に
対するピンホールの発生は解消できる。During curing, moisture vapor from the plate-like substrate can be completely removed from the cement coloring material layer, and the occurrence of pinholes in the plastic coating can be eliminated.
本考案に係る屋根材は、上述した通り、表面における防
水性は、セメント系着色層中の撥水剤によって保証され

焼付膜によって保証されている。As mentioned above, in the roofing material according to the present invention, waterproofness on the surface is guaranteed by the water repellent in the cement-based colored layer, and waterproofness on the surrounding side and back surfaces is guaranteed by the plastic baked film.
従って、全面が防水性とされているから、板状基材部へ
の浸水を確実に防止できる。Therefore, since the entire surface is waterproof, it is possible to reliably prevent water from entering the plate-like base material portion.
更に、板状基材部が、撥水剤を含有しない、強靭な組織
とされているから、機械的強度に秀れた屋根材を提供で
きる。Furthermore, since the plate-like base material part does not contain a water repellent and has a strong structure, it is possible to provide a roofing material with excellent mechanical strength.
