Description

一种磷酸酯改性丙烯酸水性工业涂料A kind of phosphate ester modified acrylic acid waterborne industrial coating

技术领域technical field

本发明涉及一种改性丙烯酸树脂水性涂料，尤其涉及到一种磷酸酯改性丙烯酸水性工业涂料，属于水性功能涂料技术领域。The invention relates to a modified acrylic resin water-based coating, in particular to a phosphoric acid ester modified acrylic water-based industrial coating, which belongs to the technical field of water-based functional coatings.

背景技术Background technique

涂料是日常生产保护基础设施不可或缺的材料，被广泛应用于建筑物、各类五金件、工业制品的装饰以及机械、车辆、船舶、飞机、仪表等领域。丙烯酸树脂涂料具有原料价格便宜、对颜料润湿性好等优点，且具有良好的施工性，在涂料领域中一直扮演着重要角色。但传统的丙烯酸树脂涂料中含有大量有机溶剂，对人体和生态环境造成严重影响。Coating is an indispensable material for daily production and protection of infrastructure. It is widely used in buildings, various hardware, decoration of industrial products, machinery, vehicles, ships, aircraft, instruments and other fields. Acrylic resin coatings have the advantages of cheap raw materials, good wettability to pigments, etc., and have good construction properties, and have always played an important role in the field of coatings. However, traditional acrylic resin paints contain a large amount of organic solvents, which have a serious impact on the human body and the ecological environment.

随着人们环境保护意识的增强，环境友好型水性涂料的生产及应用已是大势所趋。与溶剂型涂料相比，水性涂料中没有或很少含有可挥发性有机物(VOC)。其具有安全环保、成本低、施工灵活等多重优点。水性丙烯酸树脂涂料，以水为溶剂，其被广泛应用于各个领域。With the enhancement of people's awareness of environmental protection, the production and application of environmentally friendly water-based coatings has become the general trend. Compared to solvent-based paints, water-based paints contain little or no volatile organic compounds (VOC). It has multiple advantages such as safety and environmental protection, low cost, and flexible construction. Water-based acrylic resin coatings, which use water as a solvent, are widely used in various fields.

磷酸酯是一类常用的附着力促进剂，适用于铜、铁、铝、木材、塑料等各种底材，特别是对铜、铁、铝等金属基材的附着有明显促进效果，这是因为磷酸基团的强极性与基材产生了强烈的化学键合作用，但磷酸酯具有较高的酸值，一般添加量不能过多，过多会影响涂层的耐水性。Phosphate ester is a commonly used adhesion promoter, which is suitable for various substrates such as copper, iron, aluminum, wood, plastic, etc., especially for the adhesion of copper, iron, aluminum and other metal substrates. Because the strong polarity of the phosphoric acid group produces a strong chemical bond with the substrate, but the phosphoric acid ester has a high acid value, generally the amount should not be added too much, too much will affect the water resistance of the coating.

目前水性丙烯酸涂料存在防腐期限短，涂装后易闪锈，耐酸耐候性差，硬度和稳定性差等问题。同时丙烯酸酯涂料属于有机物质，成膜后遇火易燃，产生浓烟以及大量有害物质的产生，影响了其应用范围，因此对其进行阻燃性改性是非常必要的。本发明在丙烯酸酯乳液中引入含磷酸基团的不饱和单体进行共聚改性，增加乳液的交联密度，改善涂料的防腐性能与自阻燃性能。At present, water-based acrylic coatings have problems such as short anti-corrosion period, easy flash rust after coating, poor acid and weather resistance, poor hardness and stability. At the same time, acrylic paint is an organic substance, which is flammable in case of fire after film formation, produces thick smoke and a large number of harmful substances, which affects its application range, so it is very necessary to modify its flame retardancy. The invention introduces unsaturated monomers containing phosphoric acid groups into the acrylate emulsion for copolymerization modification, increases the cross-linking density of the emulsion, and improves the anti-corrosion performance and self-flame-retardant performance of the paint.

发明内容Contents of the invention

为解决所述的上述问题，本发明在聚丙烯酸酯分子结构上中引入长链烷基丙烯酸酯磷酸酯基团，磷酸酯基团上的长链烷基具有自乳化功能提高乳液的耐高温稳定性，长链烷基的疏水性能提高涂膜的耐水性；而磷酸酯基团的强极性能与基材产生了强烈的磷化键合作用，形成致密的钝化膜，由于该磷酸酯的双重作用，强化树脂与基材之间的附着力和致密性，从而有效地隔离水分子、氯离子、钠离子等进入树脂与基材之间，在湿态环境下提高附着力和抗闪锈性能，从而提高涂膜的耐水性、耐盐雾性、防锈防腐性和自阻燃性。In order to solve the above-mentioned problems, the present invention introduces long-chain alkyl acrylate phosphate groups into the polyacrylate molecular structure, and the long-chain alkyl groups on the phosphate groups have a self-emulsifying function to improve the high temperature stability of the emulsion The hydrophobicity of the long-chain alkyl group improves the water resistance of the coating film; while the strong polarity of the phosphate group produces a strong phosphating bond with the substrate to form a dense passivation film. Double function, strengthening the adhesion and compactness between the resin and the substrate, thereby effectively isolating water molecules, chloride ions, sodium ions, etc. from entering between the resin and the substrate, improving adhesion and anti-flash rust in a wet environment performance, thereby improving the water resistance, salt spray resistance, rust and corrosion resistance and self-flame retardancy of the coating film.
