In particular, the present invention relates to a mold release material composition that is made of a silicone resin solution containing a specific fine powder with a particle size of 1 μm or less and a glaze, and is capable of obtaining a coating film with a small surface roughness.

A solution in which a mold release agent such as talc is dispersed in water, oil, a solvent, a resin solution, etc., or a solution in which a binder is further added. Japanese Patent Publication No. 60-50731 discloses a silicone resin solution in which boron nitride, a glaze, and an inorganic pigment are dispersed.

いた。However, when conventional mold release agent compositions are used, there is a problem in that minute irregularities are observed on the surface of the obtained glass molded body, which reduces the transparency of the transparent glass and reduces its commercial value. Similarly, when a mold release material composition is applied to a base material, the adhesion to the base material is poor, resulting in peeling, cracking, etc.
There is a problem in that blistering occurs, which causes the surface of the glass molded product to become rough and loses its commercial value.Therefore, there has been a desire for a mold release material composition that can give a fine surface finish to the glass molded product.

有効である。70-951Lf in fine powder t(A) component such as boron nitride
%, but if the particle size of the fine powder exceeds 1 μm, the unevenness of the coating surface becomes large when applied as a mold release agent, and the transparency of the glass molded product decreases. Contains fine powder such as boron nitride f or 95! If the amount exceeds t%, the adhesion to the base material decreases and peeling, cracking, blistering, etc. occur, which roughens the surface of the glass molded product and reduces its commercial value. Furthermore, if the content of the lid is less than 7oxx%, the glaze content will be relatively high, resulting in poor lubricity and mold release properties. As the fine powder of boron nitride, carbon black such as acetylene black or furnace black, boron nitride, graphite, molybdenum disulfide, or talc can be used. Among these, acetylene black and furnace black are effective because they yield highly pure fine powder, and boron nitride is stable up to high temperatures.

If the low melting point glaze exceeds 60 mt%, the lubricity and mold releasability will deteriorate, and if it is less than 5 mt%, the adhesion to the base material will decrease, causing coating peeling and cracking, which is not preferable. Low melting point glaze is 5in2 gold as main component B2O3
, P2O5, Na2O, K2O, etc. in appropriate proportions, and commercially available products for steel plates, cast iron, stainless steel, etc. are used depending on the type of mold base material. The melting point is preferably 600 to 7008C.

できる。シリコーン樹脂は次の役割りをする。The silicone resin is present in the component (B) in an amount of 10 to 60% by weight, but if the silicone resin exceeds 601% by weight, the amount of 5102 produced by thermal decomposition of the silicone resin increases, resulting in poor mold releasability. Since SiO□ is a substance that is easily treated as glass, when the number of EIiO□ particles increases, the mold releasability deteriorates. 1011L-! If it is less than i%, the amount of SiO□ produced will be too small and the adhesion to the base material will decrease. As the silicone resin, commercially available silicone resins can be used. Also, alkyd resin, acrylic resin, phenolic resin, ebony, fs;-,? For X @b A modified silicone resin completely mixed with a silicone resin can also be used. The silicone resin plays the following role.
(1)常温から300℃までの温度での基材への密着性
全長くする。(1) Longer adhesion to the substrate at temperatures from room temperature to 300°C.
(2)粉末組成物に対し結合剤として作用する。(2) Acts as a binder for the powder composition.
(6)高温においては熱分解により生成される5in2

reacts with the glaze, becoming stable and adhering to the base material.
溶剤は(B)成分中に90〜40重量%含有させる。The solvent is contained in component (B) in an amount of 90 to 40% by weight.

分と(Bl成分とを混合する際の混合性及び基材に塗布
する際の作業性を良くするものである。When it exceeds 90% by weight, the amount of silicone resin decreases relatively and the adhesion to the base material becomes weak. Moreover, if it is less than 40% by weight, the miscibility with the powder composition becomes poor, making it difficult to uniformly disperse it, and the workability during application becomes poor. Any solvent may be used as long as it is compatible with the silicone resin, such as toluene and xylene. This improves the mixability when mixing the head component and the (Bl component) and the workability when coating the base material.

If the component (A) exceeds 60 parts by weight, the content of the Bi acid component decreases, so that the content of the Bi acid component decreases. The adhesion becomes weak, and the mixability of the (Al component and (Bl) component also deteriorates.If it is less than 2 parts by weight, the mold releasability and lubricity deteriorate, and as a result of the increase in the (A) component, the slug IJ- The viscosity decreases and component A) sediments.
