る。 The present invention replaces the extender pigment used in the conventional blackboard paint manufacturing method with a highly hardened extender pigment that is corrosion resistant. It is a super hard (a type of aqueous rock) slate, and its chemical composition is silicic anhydride (SiO 2 ) 53.54%, alumina oxide (Al 2 O 3 ) 16.79%, iron oxide (Fe 2 O 3 ) 7.23% Calcium oxide (CaO) 8.63% Magnesium oxide (MgO) 3.12% Sodium oxide (Na 2 O) 6.92% Potassium oxide (K 2 O) 1.84% Loss on ignition (H 2 O) 7.65% Sulfur (S) 0.15% Total 99.96 % or more is crushed and crushed into a fine powder of 250 mesh or more (hereinafter referred to as Spuda Black Hardstone). This is adopted as an extender pigment by applying it to a manufacturing method of a certain high-hardness blackboard paint, and although this kind of manufacturing process is the same as the known blackboard paint manufacturing process, the nature of the present invention is The outline of its purpose is as follows.

塗料の製造方法にかかわる。 The extender pigment uses powdered black hardstone, and the coloring pigment is an appropriate combination of iron oxide yellow and phthalocyanine blue, and then the presence of a mineral turpentine solvent.
The present invention relates to a method for producing a highly hard blackboard paint with corrosion resistance, in which a phthalic acid-based synthetic resin paint is polymerized and mixed, and a stirring process is performed.

加工して仕上げるものである。 The purpose of this is to paint the surface of the pre-treated blackboard board, regardless of whether it is made of plywood or steel, with a spatula or with a spray paint machine, and then dry it at room temperature or heat it with hot air. After this surface coating has completely dried and hardened, it is finished by processing it to an appropriate micrometer-order roughness.

に富む優れた特性がある。これらの特性を有する
ためつぎに述べる利点を発揮し得る。 The quality and performance of this blackboard surface lies in the toughness and hardness of the surface coating film, which is the object of the present invention. For this reason, powdered black hardstone was newly used as an extender pigment. The raw stone of this extender pigment is slate, which belongs to a highly consolidated aqueous rock, and is extremely dense with almost no water absorption and high hardness.This fine powder has good miscibility with the vehicle and has elasticity. The coating surface formed from a color vehicle and a corrosion-resistant color pigment is hard and tough, has no moisture absorption, and has excellent corrosion resistance. Because it has these characteristics, it can exhibit the following advantages.
(1) 反復使用に際し、表面粗さの形状はほとんど
変化せず、切刃となる体質顔料粒子は扁平化す
ることがない。従つて反射光沢の増進は皆無に
等しく、安定した視覚環境が永続できる。(1) During repeated use, the shape of the surface roughness hardly changes, and the extender particles that form the cutting edge do not flatten. Therefore, the increase in reflective gloss is negligible, and a stable visual environment can be maintained permanently.
(2) 耐食性については塩酸、苛性ソーダの各５％
水溶液を用いて点滴試験を行なつたところ、塗
膜面になんらの異状も認められず変退色するこ
とがない。(2) For corrosion resistance, use 5% each of hydrochloric acid and caustic soda.
When a drip test was conducted using an aqueous solution, no abnormalities were observed on the coating surface, and no discoloration or fading occurred.
(3) 黒板面を水平面に対し75゜の勾配に設置、８
ｍの距離よりチヨークの着き及びふき消しの状
態を観察したところ、白墨、色チヨークを問わ
ず描書は鮮明で、チヨークタツチも快適で且つ
粉末の滑落落下がスムーズであるばかりでな

跡は勿論、、消しむらも認められず、黒板面は
常に清明さを保つことができる。(3) Place the blackboard surface at an angle of 75° to the horizontal plane, 8
When observing the application and wiping-off condition of the yoke from a distance of m, it was found that the writing was clear regardless of whether it was chalk or colored yoke, the yoke touch was comfortable, and not only did the powder slide down smoothly, but it was also easy to wipe it off. It is very easy to do, and there are no traces of chalk or even erased areas, and the blackboard surface always remains clear.
(4) 硬度については4H以上の硬さをもつ鉛筆を
用い線書きしても表面塗膜に引掻ききずを生じ
ない。(4) Regarding the hardness, even if you draw with a pencil with a hardness of 4H or higher, the surface coating will not be scratched.
(5) 塗膜面は前述の如く硬質且つ強靭性を有する
が、研ぎ出し仕上げは容易で、その表面はきわ
めて平滑である。それにもかかわらず鏡面光沢
度は小さい。(5) As mentioned above, the coating surface is hard and tough, but it is easy to polish and the surface is extremely smooth. Despite this, the specular gloss is low.
(6) 塗膜の密着が強靭で且つ耐食性である故、外
触による老化の憂いがなく、黒板性能の低下は
きわめて少なく、耐用性に優れている。(6) Since the coating film has strong adhesion and is corrosion resistant, there is no concern about aging due to external contact, there is very little deterioration in blackboard performance, and it has excellent durability.
