Description

喷涂型紫外光固化木器清面漆技术领域 Sprayed UV-curable clear coat wood Technical Field

[0001] 本发明属于一种涂料,具体涉及一种喷涂型紫外光固化涂料,特别适用于多种木质基材(如实木、胶合板、刨花板、密度板等)产品的面漆罩光。 [0001] The present invention pertains to a coating, in particular to a spray-type UV-curable coatings, more particularly suitable for wooden substrates (e.g., wood, plywood, particleboard, MDF, etc.) topcoat varnish products.

背景技术 Background technique

[0002] 紫外光(ultraviolet ray,缩写为UV)固化涂料(以下简称UV涂料),因具有品质优越、生产效率高、成本低、环保性能好等因素,自问世以来即得到快速发展,尤其在木制地板行业,其应用范围几乎达到100%,是一种极具发展前途的优质产品,被誉为未来涂料发展的方向。 [0002] UV (ultraviolet ray, abbreviated UV) curable coatings (hereinafter referred to as UV coating), due to the superior quality, high efficiency, low cost, good environmental performance and other factors, that is, since the advent of rapid development, especially in wooden flooring industry, and their use almost 100%, is a highly promising high-quality product, known as the direction of future development of paint. 但是,目前UV涂料涂装方式仍以辊涂和淋涂(适用于高粘度涂料)为主,这主要是由于UV涂料本身为高固含量涂料,通过采用活性稀释剂降低粘度是一个技术难点:降低UV涂料粘度用于喷涂的传统方法是加入惰性稀释剂(不参与固化反应的稀释剂,如丙酮、二甲苯等),而惰性稀释剂易挥发,使得这种方法本身与UV涂料的高环保性能有矛盾;也有单纯通过加入活性稀释剂降低UV涂料粘度的,但是普遍效果不佳,主要表现在降低粘度的同时降低了涂料的其它性能,比如固化性能、硬度、光泽度等。 However, the current embodiment still UV paint coating and flow coating, roll coating (for high viscosity coatings) based, which is mainly due to UV coating high solids coating itself, lowering the viscosity by using a reactive diluent is technical difficulties: traditional methods for reducing the viscosity of the UV coating spray is added to an inert diluent (diluent does not participate in the curing reaction, such as acetone, xylene, etc.), volatile and an inert diluent, such that this method itself with high environmental UV coatings contradictory properties; also simply by adding a reactive diluent to reduce the viscosity of the UV coating, but the generally poor results, mainly to reduce the viscosity while reducing other coating properties, curing properties such as hardness, gloss and the like.

[0003] 另外,辊涂和淋涂只能适用于单面板式物件的涂装,不能涂装任意形状的工件,要实现任意形状物件的紫外光固化涂料的涂装,必须对现有的UV涂料涂装设备设施、工艺技术等相关因素进行全面改进,其中最关键就是将以前的辊涂、淋涂改为喷涂。 [0003] Further, flow coating, roll coating, and the coating applied to only one surface of the object plate, an arbitrary shape can not paint the workpiece, to achieve an arbitrary shape object coated UV-curable coatings must be of conventional UV factors paint coating equipment, facilities, technology and other comprehensive improvements, the most critical is the former roller coating, curtain coating was altered. 近年来经各相关科研部门、涂料生产企业、设备生产企业及生产技术人员的努力,UV涂料喷涂技术已取得突破性进展,在某些领域已进入实用阶段。 In recent years, through the efforts of relevant scientific research departments, paint manufacturers, equipment manufacturers and production technicians, UV paint spraying technology has made breakthrough progress in some areas has entered a practical stage. 但整个技术体系还未完全成熟,很多问题有待进一步完善,其中喷涂型UV涂料开发滞后是主要问题之一。 But the whole system is not yet fully mature technology, a lot of issues to be further improved, in which the spray-on UV coating development lag is a major problem. 此前,UV涂料的研发、生产集中于辊涂和淋涂方面,喷涂型UV涂料属待开发产品,市场上成熟的产品不多见,多数产品存在以下问题:粘度高、难操作、流平性差、张力大或助剂使用不当,造成涂层缩孔、柔性、硬度失调导致涂料膜开裂等等。 Previously, the development of UV coating, roll coating, and concentrated in production curtain coater aspects UV coating sprayed metal product to be developed, are rare on the market mature products, most products the following problems: high viscosity, difficult to operate, poor leveling , tension is improper use or adjuvants, resulting in the coating shrinkage, flexibility, hardness imbalance leads to cracking of the paint film and the like.

[0029] 本发明的有益效果是: [0029] Advantageous effects of the present invention are:

[0030] I.用双酚A环氧丙烯酸酯作为紫外光固化涂料的主体活性齐聚物,由于将主体齐聚物40%左右的传统用量降至30%以内,从而降低产品的硬脆性。 [0030] I. oligomer bisphenol A epoxy acrylate as a main activity of UV-curable coatings, since the conventional body oligomer amount of about 40% down to less than 30%, thereby reducing the hard and brittle products. 由于该油涂料为喷涂型油涂料,所形成的涂料膜比辊涂、淋涂的厚,为防止应力累积,需缓解环氧丙烯酸酯的硬脆性,避免涂料膜开裂。 Since the oil paint is sprayed oil paint, a paint film is formed over roll coating, curtain coating thickness, in order to prevent accumulation of stress, hard and brittle to be alleviated epoxy acrylate, to avoid cracking of the paint film.

[0031] 2.配合使用三官能度脂肪族聚氨酯丙烯酸酯和六官能度的聚氨酯树脂,前者可以增加涂料的柔性,后者可以保证整个配方的固化速率。 [0031] 2. The polyurethane resin used in conjunction with trifunctional aliphatic urethane acrylate and hexafunctional, the former can increase the flexibility of the coating, which can ensure that the curing rate of the total formulation. 三官能度脂肪族聚氨酯丙烯酸酯柔性良好,和双酚A环氧酯协同作用,可以充分显现出刚柔相济的性能;但因其聚合度较差,反应速率低,在配方中如果使用过量,会产生涂料膜固化不彻底,抗划性能差,甚至发粘等缺陷,因此加入一定量的六官能度的聚氨酯树脂,该树脂不但有一定的柔顺性,兼具很高的聚合度,使其固化速率大为提高。 Trifunctional aliphatic urethane acrylate good flexibility, and bisphenol A epoxy acrylate synergy, can fully exhibit the properties of hardness and softness; but because of its poor degree of polymerization, the reaction rate is low, if an excessive amount in the formulation, will produce not completely cured paint film, poor scratch resistance, and even tacky defects, so a certain amount of the hexafunctional urethane resin, the resin not only has a certain flexibility, both a high degree of polymerization, curing rate greatly improved.

[0032] 3.大量使用活性稀释剂以降低粘度,并配合使用三丙二醇二丙烯酸酯和丙氧基化三羟甲基丙烷三丙烯酸酯两种活性稀释剂,前者粘度低、稀释能力强,并且具有很好的柔顺性,对降低产品的粘度起着至关重要的作用;后者在降低产品粘度的同时,提高了固化速率,增加了涂料膜的韧性。 [0032] 3. The use of a large number of reactive diluent to reduce the viscosity, and with the use of tripropylene glycol diacrylate and propoxylated trimethylolpropane triacrylate two active ester diluent, the former low viscosity, high dilution capacity, and It has good flexibility, to reduce the viscosity of the product plays a vital role; latter reducing the viscosity of the product at the same time, to improve the cure rate, increase the toughness of the paint film.

[0033] 4. 2700的基材润湿剂兼有基材润湿、脱泡、流平等作用;432的基材润湿剂具有优异的基材润湿功能,又有很好的流平,抗划伤作用,二者并用使产品的施工性能及涂层的外观质量有明显的提高。 [0033] 4.2700 substrate wetting both the substrate wetting, the defoaming, the flow equal effect; 432 substrate wetting agent having excellent substrate wetting function, but also a very good flow, scratch effect, both with and that the workability and appearance quality of the coated product is significantly improved.

[0034] 5.利用各种原料的合理组合,使涂料具有粘度低、施工(喷涂)性能好、在几乎不降低硬度等性能的前提下赋予涂层足够的柔顺性等特点,有效地避免了橘皮、凹陷等问题的产生,使得喷涂型UV涂料进一步走向成熟。 [0034] The various raw materials using a combination of rational, the coating having a low viscosity, construction (spraying) and good performance, to impart sufficient flexibility under the premise of a coating hardness hardly reduced performance characteristics, effectively avoid the orange peel problem, recess, etc., so that the UV coating further sprayed maturity.
