Description
本発明は建築塗料技術分野に属し、具体的には赤外線と紫外線を遮蔽する水性メラミン樹脂塗料及びその製造方法に関する。 The present invention belongs to the field of architectural paint technology, and specifically relates to an aqueous melamine resin paint that shields infrared rays and ultraviolet rays, and a method for producing the same.
水性メラミン樹脂塗料は、家、ホテル等の内装に広く使用されている内壁用塗料である。水性メラミン樹脂塗料は一般的に、溶剤型メラミン樹脂塗料と水性エマルジョンメラミン樹脂塗料に分けられる。溶剤型メラミン樹脂塗料は硬化中に、有毒な揮発性溶剤を放出し、労働者や住戸の身体の健康を脅かし、環境保護の要求に適合しないため、応用において制限される。一方、化学工業、冶金、熱間加工などの特殊な分野では、150℃を超える発熱体が赤外放射を発生することにより、塗料の断熱性能が急激に低下し、熱伝導率が急激に上昇し、塗料がより速く割れて剥げ、生産過程の安全性に影響を及ぼすため、耐赤外線性と耐紫外線性の良い、環境に優しいメラミン樹脂塗料を調製する必要があるが、現在では、それに関する研究報告が少ない。
CN105199515Aには、PPプライマーと、中層水性メラミン樹脂塗料と、表層UV塗料とから構成されるメラミン樹脂塗料及びその塗装方法が開示され、従来の塗料におけるプライマーが割れやすい問題と、中層が相対的に硬度が低い問題と、耐候性、耐老化性、層間付着力が劣る問題とを解決した。しかし、このメラミン樹脂塗料は、コストが高く、塗装が面倒であり、抗赤外放射性が普通であり、適用範囲が制限されている。
CN108219666Bには、改質ポリイミド樹脂溶液と、方解石と、二酸化チタンと、ベントナイトと、断熱エアロゲル粒子とを含む、耐赤外線、静菌、耐候性の水性メラミン樹脂塗料及びその製造方法が開示されているが、改質ポリイミド樹脂溶液の調製過程でホルムアルデヒドが使用され、ホルムアルデヒドは常温で気体であり、発がん性物質であり、人体や環境に毒があるため、この耐赤外線、静菌、耐候性の水性メラミン樹脂塗料の製造方法を採用して製造した水性メラミン樹脂塗料は安全性の問題が存在する。
CN109385163Aには、赤外線と紫外線を全部遮蔽するPEEK改質アクリル酸水性透明断熱塗料が開示され、この水性透明断熱塗料は、PEEK改質水性アクリル樹脂、ナノ透明断熱剤、ナノ光触媒、透明ナノカラーペーストなどの材料からなり、優れた耐放射線性を有するが、ナノ透明断熱剤に添加されるWO3は、皮膚に刺激性を有し、人体安全に不利であり、また、製造工程が複雑であり、1000hの耐湿熱、耐劣化性能試験のみを行い、耐候性が不足している。
The water-based melamine resin paint is a paint for interior walls that is widely used in the interior of houses, hotels, and the like. Water-based melamine resin paints are generally divided into solvent-based melamine resin paints and water-based emulsion melamine resin paints. Solvent-type melamine resin paints are limited in application because they release toxic volatile solvents during curing, threaten the physical health of workers and dwelling units, and do not meet environmental protection requirements. On the other hand, in special fields such as the chemical industry, metallurgy, and hot working, the heat insulating performance of the paint drops sharply and the thermal conductivity rises sharply due to the generation of infrared radiation by the heating element exceeding 150 ° C. However, because the paint cracks and peels off faster and affects the safety of the production process, it is necessary to prepare an environmentally friendly melamine resin paint with good infrared resistance and ultraviolet resistance, but nowadays, it is related to that. There are few research reports.
CN105199515A discloses a melamine resin paint composed of a PP primer, a middle layer water-based melamine resin paint, and a surface layer UV paint, and a coating method thereof. The problem of low hardness and the problem of poor weather resistance, aging resistance, and interlayer adhesion have been solved. However, this melamine resin paint is expensive, cumbersome to paint, usually has anti-infrared radioactivity, and its scope of application is limited.
CN108219666B discloses an infrared-resistant, bacteriostatic, and weather-resistant water-based melamine resin coating material containing a modified polyimide resin solution, a calcified stone, titanium dioxide, bentonite, and adiabatic aerogel particles, and a method for producing the same. However, formaldehyde is used in the process of preparing the modified polyimide resin solution, and formaldehyde is a gas at room temperature, is a carcinogenic substance, and is toxic to the human body and the environment. The water-based melamine resin paint produced by adopting the method for producing the melamine resin paint has a safety problem.
CN109385163A discloses a PEEK-modified acrylic acid water-based transparent heat insulating paint that shields all infrared rays and ultraviolet rays, and the water-based transparent heat insulating paint includes a PEEK-modified water-based acrylic resin, a nanotransparent heat insulating agent, a nanophotocatalyst, and a transparent nanocolor paste. WO3, which is made of such materials and has excellent radiation resistance, is irritating to the skin, is disadvantageous to human safety, and the manufacturing process is complicated. Only 1000h of moisture resistance and deterioration resistance performance test is performed, and the weather resistance is insufficient.
本発明は、上記の技術的課題を解決するために、赤外線と紫外線を遮蔽する水性メラミン樹脂塗料及びその製造方法を提供することを目的とする。 An object of the present invention is to provide an aqueous melamine resin coating material that shields infrared rays and ultraviolet rays and a method for producing the same, in order to solve the above technical problems.
