技术领域 technical field
本发明涉及建筑防水领域，具体涉及一种防水阻燃密封涂料及其制备方法。 The invention relates to the field of building waterproofing, in particular to a waterproof and flame-retardant sealing coating and a preparation method thereof.
背景技术 Background technique
防水技术是保证工程质量，避免水侵蚀危害的一项专门技术，并在工程建设中占有重要的地位。日常生活中，屋内地面渗漏、宾馆卫生间渗漏和潮湿，地下工程渗漏和潮湿等是普遍存在的问题。水是一种极性物质，表面张力约为72mN/m，扩散性很强，能够润湿多种物质，不但能在重力下通过较大的空隙通道进行流动，并且能够通过毛细孔向各个方向扩散，因此解决工程渗漏和潮湿问题的有效途径是研制和应用防水材料。 Waterproof technology is a specialized technology to ensure project quality and avoid water erosion hazards, and it occupies an important position in project construction. In daily life, ground leakage in houses, leakage and humidity in hotel toilets, leakage and humidity in underground projects are common problems. Water is a polar substance with a surface tension of about 72mN/m. It has strong diffusivity and can wet a variety of substances. It can not only flow through large void channels under gravity, but also flow in all directions through capillary pores. Therefore, an effective way to solve engineering leakage and moisture problems is to develop and apply waterproof materials.
传统的防水材料主要有防水卷材、防水涂料、密封油膏等柔性防水材料，以及以水泥基材为主，添加药水剂及其它助剂的刚性防水材料。我国大部分防水工程均采用传统防水材料，传统防水材料存在着耐老化性能差、拉伸强度低、对温度敏感等缺点。传统防水涂料用来屋面防水，容易引起老化、干裂、变形、折断、分层等现象，用于室内防水，对于形状复杂的场所，施工困难，而对渗漏现象，质量更难以保证，人们每隔几年就要花费大量的资金和劳动力进行返修，不仅搅乱了人们的正常生活、工作和生产秩序，而且影响整幢致密抗渗漏物的使用寿命。为了满足各行业对防水涂料的要求，生产高性能，防水涂料的研究开发极为重要。 Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added with liquid medicine and other additives. Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breakage, delamination, etc. When used for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. A lot of money and labor will be spent for repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire dense anti-leakage building. In order to meet the requirements of various industries for waterproof coatings and produce high performance, the research and development of waterproof coatings is extremely important.

Use a sand mill to grind and grind to a fineness of about 50-100 μm, and then sieve and pack into barrels to obtain a finished product.
本发明中所用的拉开粉主要成分是丁基萘磺酸钠，能显著降低水的表面张力，具有优良的渗透力与润湿性，再润湿性也极佳，并具有乳化、扩散和起泡沫性能。本发明中主要利用拉开粉的降低水表面张力、乳化、扩散性质，来辅助各种粉料充分溶于水中并与改性丙烯酸酯、SBS改性沥青相互配合，制成性能优异的浆料。 The main component of the pull-away powder used in the present invention is sodium butylnaphthalene sulfonate, which can significantly reduce the surface tension of water, has excellent penetration and wettability, and has excellent rewetability, and has emulsification, diffusion and Foaming properties. In the present invention, the characteristics of reducing water surface tension, emulsification, and diffusion of the pull-off powder are mainly used to assist various powders to fully dissolve in water and cooperate with modified acrylate and SBS modified asphalt to make a slurry with excellent performance .
本发明专利中的防水涂料，由于利用改性丙烯酸酯与SBS改性沥青作为水乳型双组分材料，具有耐候、耐温性能好，能在潮湿基面上直接施工，与基层黏结性能好，无毒、无污染，施工简单方便等优点。涂料固化后，能在基面上形成一层没有接缝、富有弹性的整体防水层。还可以与其他防水卷材一起组成复合防水层。与其他涂料或单纯沥青、单纯丙烯酸酯涂料相比，本发明专利中涂料最大的优点就是在施工方便，施工时无需加热，冷施工，可刮，可刷，拉伸强度高、阻燃性好，防水性能好。 The waterproof coating in the patent of the present invention uses modified acrylate and SBS modified asphalt as a water-emulsion two-component material, which has good weather resistance and temperature resistance, can be directly applied on a wet base surface, and has good bonding performance with the base layer , non-toxic, non-polluting, simple and convenient construction and other advantages. After the coating is cured, it can form an integral waterproof layer with no seams and high elasticity on the base surface. It can also be combined with other waterproof membranes to form a composite waterproof layer. Compared with other paints or pure asphalt and pure acrylate paints, the biggest advantage of the paint in the patent of the present invention is that it is convenient for construction, no heating is required during construction, cold construction, scratchable, brushable, high tensile strength, and good flame retardancy , good waterproof performance.
本发明中利用SBS改性沥青与改性丙烯酸酯配合，在生产、施工和应用过程中均不会产生污染物质，绿色环保，涂膜具有良好拉伸强度、断裂伸长率、低温柔性以及对基材的粘结强度，无机粉料的加入则进一步强化了涂料的物理性能。 In the present invention, the combination of SBS modified asphalt and modified acrylate will not produce pollutants during production, construction and application, and is environmentally friendly. The coating film has good tensile strength, elongation at break, low temperature flexibility and The bonding strength of the substrate and the addition of inorganic powder further strengthen the physical properties of the coating.
本发明中利用改性丙烯酸酯为涂料中的主要成分因其共聚物主链为饱和结构，侧基为极性的酯基，因此具有优异的户外耐老化性、优异的“呼吸性”、对各种基材的粘附性，故以丙烯酸酯共聚物形成的涂膜具有优异的保光、保色、对潮湿环境的适应性。另一方面，丙烯酸酯单体种类多、玻璃化转变温度(Tg)宽，因此其共聚物的耐寒温度可以达到-30℃，也可将共聚物设计成Tg高达60℃的涂层，因此丙烯酸酯聚合物作为涂料成膜物质是其他任何聚合物都不可比拟的，现已成为建筑涂料的第一大涂料。丙烯酸酌共聚物虽具上述独一无二的优点，因其极性酯侧基也决定了它们耐碱性和耐水性差等缺点，故采用与有机硅氧烷共聚来解决这些问题。有机硅树脂中Si-O键能远大于C-C键能和C-O键能，因此具有优良的耐高温性、耐氧化降解性及化学品性；有机硅丙烯酸酯是采用物理混拼法或化学共聚法对丙烯酸树脂进行改性，改性后的树脂兼具有有机硅树脂高耐候、高抗水、高耐沾污、高防腐性以及丙烯酸树脂的柔韧性、高附着性等优点。 In the present invention, the modified acrylate is used as the main component of the coating because the main chain of the copolymer is a saturated structure, and the side group is a polar ester group, so it has excellent outdoor aging resistance, excellent "breathability", and Adhesion to various substrates, so the coating film formed by acrylate copolymer has excellent gloss retention, color retention, and adaptability to humid environment. On the other hand, there are many types of acrylate monomers and a wide glass transition temperature (Tg), so the cold-resistant temperature of its copolymer can reach -30°C, and the copolymer can also be designed as a coating with a Tg as high as 60°C, so acrylic acid As a coating film-forming substance, ester polymer is unmatched by any other polymer, and has become the largest coating for architectural coatings. Although acrylic acid copolymers have the above unique advantages, their polar ester side groups also determine their shortcomings such as poor alkali resistance and water resistance, so they are copolymerized with organosiloxane to solve these problems. The Si-O bond energy in silicone resin is much greater than the C-C bond energy and C-O bond energy, so it has excellent high temperature resistance, oxidative degradation resistance and chemical resistance; silicone acrylate is produced by physical mixing method or chemical copolymerization method The acrylic resin is modified, and the modified resin has the advantages of high weather resistance, high water resistance, high stain resistance, high corrosion resistance of silicone resin, and the flexibility and high adhesion of acrylic resin.
由于丙烯酸酯乳液含有表面活性剂或具有表面活性剂的特性，本身容易产生气泡，而气泡易造成涂料成膜后表面裂纹和气孔，不利于防水，故本发明中采用聚醚改性硅氧烷作为消泡剂，提高整个涂料的性能。 Since acrylate emulsion contains surfactant or has the characteristics of surfactant, it is easy to generate bubbles, and the bubbles are easy to cause surface cracks and pores after film formation of the coating, which is not conducive to waterproofing, so polyether modified siloxane is used in the present invention Acts as a defoamer to improve the performance of the overall coating.
本发明中所述有机硅改性丙烯酸酯可以采用由氯硅烷与丙烯酸酯反应制备的；也可以采用特定商品牌号的，如山东东明石化集团科耀化工有限公司生产的有机硅改性丙烯酸树脂DS-50Ⅱ。 The organosilicon-modified acrylic ester described in the present invention can be prepared by the reaction of chlorosilane and acrylate; it can also adopt a specific brand name, such as the organosilicon-modified acrylic resin DS produced by Shandong Dongming Petrochemical Group Keyao Chemical Co., Ltd. -50Ⅱ.
本发明中，通过选择合适的原料，控制各原料的含量，使各原料处于最优比例，各原料的优势协同促进，得到的涂料阻燃性好，耐热性强，强度高，用作阻燃涂料使用寿命长。本发明中利用两种阻燃物配合使用，提高涂料阻燃性能。 In the present invention, by selecting appropriate raw materials and controlling the content of each raw material, each raw material is in an optimal ratio, and the advantages of each raw material are synergistically promoted, and the obtained coating has good flame retardancy, strong heat resistance, and high strength. Combustible coatings have a long service life. In the present invention, two kinds of flame retardants are used together to improve the flame retardant performance of the coating.
