Abstract

The invention discloses a double-curing varnish paint which is prepared from the following components in parts by mass: 3-6 parts of double-curing varnish, 1 part of curing agent and 0.5-1 part of diluter. The double-curing varnish comprises the following components in percentage by mass: 10-60% of hydroxy acrylic resin, 10-30% of UV (ultraviolet) resin, 1-30% of active diluter, 0.5-4% of photoinitiator, 1-3% of antiaging agent, 1-3% of leveling agent, 1-3% of drying agent and 10-30% of solvent. The double-curing varnish paint uses the free-radical polymerization-polycondensation curing system; under the irradiation of UV, the UV resin in the double-curing varnish forms free-radical polymerization under the action of the photoinitiator, and the -OH group contained in the hydroxy acrylic resin in the double-curing varnish and the -NCO group contained in the isocyanate resin in the curing agent are subjected to addition polymerization under the action of heat energy; and the polymers formed by the two polymerization reactions become an mutually-wound endosmosis network structure, thereby enhancing the weather resistance and chemical corrosion resistance of the paint film.

Description

双重固化清漆涂料 Dual-cure clearcoat paint

技术领域 FIELD

[0001] 本发明涉及一种双重固化清漆涂料,更具体地说,本发明涉及一种可通过紫外光固化和热固化的双组份清漆涂料。 [0001] The present invention relates to a dual cure clear coating and, more particularly, the present invention relates to a by UV curing and thermal curing of the two-component clearcoat paint.

技术背景 technical background

[0002] 紫外光固化涂料(UV涂料)具有干燥迅速、硬度高、生产周期短等优点,近年来得到快速发展,但是,传统的紫外光固化涂料也存在一些缺陷,例如涂层硬度与韧性之间的矛盾。 [0002] UV-curable coatings (UV coatings) having a fast drying, high hardness, short production cycle, etc., in recent years, rapid development, however, the conventional UV-curable coatings, there are some drawbacks such as hardness and toughness of the coating the contradiction between. 紫外光固化涂料的涂层是高度交联的,容易达到高硬度,但韧性却不能确保,因此无法满足对硬度有要求同时还要耐冲击的应用领域。 UV-curable coating material is highly crosslinked, easy to achieve high hardness, but it can not ensure the toughness, and therefore can not meet the requirements of hardness but also has impact resistance applications. 另外,当紫外光直接照射到涂膜,使涂膜获得足够的辐照强度时,固化后的涂膜才能达到最佳的性能指标,对于不易被照射到的阴影部位,则无法获得足够的辐照强度。 Further, when ultraviolet light is directly irradiated to the coating film, the coating film strength sufficient irradiation, the coating film after curing to achieve the best performance, easy to be irradiated to the hatched area, you can not obtain sufficient radiation according strength. 再者,紫外光固化涂膜的耐候性不足,由于紫外光照射时不能理想地消耗全部光引发剂,而残留的光引发剂受自然界紫外光的刺激产生基团,导致涂膜变黄和劣化。 Further, the UV cured coating film is insufficient weather resistance, because it is not desirable to consume all the light is ultraviolet light initiator, photoinitiator remaining natural stimulant ultraviolet light generated by the group, resulting in deterioration of the coating film and yellowing . 紫外光固化速度快(固化时间以秒计),可大幅度缩短固化时间,但其反作用是固化时产生的涂膜的残留应力要比热固化型涂料大数十倍,容易造成涂膜开裂。 UV curing speed (curing time in seconds), can greatly reduce the curing time, but the reaction is produced when the residual stress than a cured coating film of a thermosetting coating several tens of times, is likely to cause the coating to crack. 因此,紫外光固化涂料在某些领域的应用受到限制,特别是对漆膜性能要求较高的汽车和摩托车外表面涂料。 Thus, application of UV-curable coatings in certain areas is limited, especially for high performance requirements of the film's outer surface coating cars and motorcycles.
