Regarding alkaline paints, when the alkaline paints are applied to iron materials, γ-Fe2O3 is formed on the surface of the iron materials due to its alkalinity (particularly in the pH range of 12.2 or higher), which provides a rust-preventing effect. Moreover, when painted on concrete, because of its alkaline nature, neutralization of the concrete is prevented and rusting of reinforcing bars is prevented.

あった。[Problems to be Solved by the Invention] However, since conventional alkaline paints use the above-mentioned polymer as a base, the polymer decomposes at about 100 to 120°C, causing damage to chimney interiors and ALC paints. It cannot be used for painting reinforcing steel. (Incidentally, the autoclave processing conditions for ALC are usually about 7 atmospheres of saturated steam, 180°C, and 10 atm.) Therefore, conventionally, glass lining or silicone resin coatings were used for such heat-resistant coatings. However, there were problems such as the painting work being complicated and extremely expensive.

なお、本発明において、塗料を構成する各成分の配合割
合の限定理由は下記の通りである。In the present invention, the reason for limiting the blending ratio of each component constituting the paint is as follows.
■ ノボラック型エポキシ樹脂オリゴマー：ノボラック
型エポキシ樹脂オリゴマーの配合量が１２重量部未満で
は、塗膜の緻密化が不足し、良好な塗膜形成能が得られ
ない。２０重量部を超えるとセメントによる剛性が落ち
る。(2) Novolac type epoxy resin oligomer: If the amount of the novolac type epoxy resin oligomer is less than 12 parts by weight, the coating film will not be sufficiently dense and good coating film forming ability will not be obtained. If it exceeds 20 parts by weight, the rigidity due to cement will decrease.
従って、１２〜２０１ｉ量部とする。Therefore, the amount should be 12 to 201i parts.
■ 界面活性剤：
界面活性剤が０．５重量部未満では、良好な乳化液が得
られない、５重量部を超えても効果は上昇せず不経済で
ある。従って、０．５〜５重量部とする。(2) Surfactant: If the surfactant is less than 0.5 parts by weight, a good emulsion cannot be obtained, and if it exceeds 5 parts by weight, the effect will not increase and it will be uneconomical. Therefore, the amount should be 0.5 to 5 parts by weight.
■ 水： 水はセメントが水和して水を吸収するために添加する。■ Water: Water is added to allow the cement to hydrate and absorb water.
水が４５重量部未満ではセメントの水和に不足し、１２
０重量部を超えると水が遊離し、塗料エマルジョンの濃
度が均一化しない。従って、４５〜１２０重量部とする
。If the water content is less than 45 parts by weight, the hydration of the cement will be insufficient, and 12
If it exceeds 0 parts by weight, water will be liberated and the concentration of the paint emulsion will not be uniform. Therefore, the amount is set at 45 to 120 parts by weight.

If the amount of aggregate exceeds 40 parts by weight, the ability to form a coating will deteriorate. Therefore, the amount of aggregate should be less than 40%, preferably less than 1/3, especially less than 1/4 of the cement weight.

ものとなっている。Moreover, since it contains cement, the cement hydrate forms a film, and the heat resistance of the coating film is higher than that of the resin alone.
加えて、セメントを含んでいるためアルカリ性であり、
コンク、リートの中性化や鉄筋の防錆が行なわれる。上
記樹脂は、このセメント水和物皮膜を緻密なものとし、
セメント永和物の中性化を防止する。In addition, it is alkaline because it contains cement.
Concrete and reeit will be neutralized and reinforcing bars will be rust-proofed. The above resin makes this cement hydrate film dense,
Prevents carbonation of cement permanent products.
また、骨材を配合することにより、得られる塗膜の重防
食化が図れ、耐熱性、耐摩耗性が大幅に改善される。In addition, by incorporating aggregate, the resulting coating film can be heavily anticorrosive, and its heat resistance and abrasion resistance are significantly improved.
