Description

一种金邦板表面处理工艺 One kind of a surface treatment process jinbang

技术领域 FIELD

[0001] 本发明涉及一种金邦板表面处理工艺。 [0001] The present invention relates to a surface treatment process jinbang plate.

背景技术 Background technique

[0002] 建筑材料本色装饰效果,即表面看不出任何涂饰过的痕迹,是建筑装饰的一大流派。 [0002] Building materials decorative qualities that can not see any surface finishing at the scene, is a major genre of architectural decoration. 有的装饰材料如陶土板其生产工艺决定了其不用表面保护就能直接使用,而以无机胶凝材料为基材,复合纤维增强,采用先进的高压真空挤出工艺生产的金邦板的生产工艺决定了其表面必须要进行保护。 Some producing decorative sheet material, such as clay which determines its manufacturing process can be used directly without surface protective, and inorganic binder as base material, a fiber-reinforced composite, the use of advanced high voltage vacuum extrusion process for producing panels jinbang process to determine its surface must be protected.

[0003] 对金邦板的表面进行保护通常采用的工艺是涂覆具有表面荷叶效果的材料。 [0003] surface of the plate jinbang protection for process generally employed is a material having a surface coated with lotus effect. 表面荷叶效果主要是指荷叶表面具有超疏水以及自洁的特性。 Lotus effect mainly refers to the surface of lotus leaf surface having superhydrophobic and self-cleaning properties. 由于荷叶具有疏水、不吸水的表面,落在叶面上的雨水会因表面张力的作用形成水珠,换言之,水与叶面的接触角会大于150度,只要叶面稍微倾斜,水珠就会滚离叶面;此外,滚动的水珠会把一些灰尘污泥的颗粒一起带走,达到自我洁净的效果。 Since the lotus hydrophobic, non-absorbent surface, rain fall on the leaf surface formed by the action of the surface tension of the drops, in other words, the contact angle of water with the leaf will be greater than 150 degrees, as long as the leaf is slightly inclined, water droplets it will roll away from the leaf; in addition, water droplets will roll some of the dust particles away with the sludge, to achieve self-cleansing effect.

[0004]目前市场上有很多类材料具有表面荷叶效果。 [0004] Currently on the market there are many types of surface material having a lotus effect. 如硅烷类、硅氧烷类、硅酸盐类等,但性能较好的是硅烷类、硅氧烷类,但这二者也有不同处,硅烷类渗透性好,持久性强,但表面荷叶效果不明显,而硅氧烷类正相反。 Such as silanes, siloxanes, silicates and the like, but the properties are preferably silanes, siloxanes, but there are two differences, silanes good permeability, durable and strong, but the surface charge leaves little effect, whereas the opposite silicones. 现有的金邦板的表面处理,只是单独使用其中的一种,不能兼顾。 Jinbang surface treatment of existing plates, except that one of them alone can not be taken into account.

[0005] 因此,需要一种适用于金邦板的改进的表面处理工艺。 [0005] Accordingly, a need for an improved jinbang plate suitable surface treatment.

[0006] 发明概述 [0006] Summary of the Invention

[0007] 本发明的目的是提供一种金邦板表面处理工艺。 [0007] The object of the present invention is to provide a plate surface treatment jinbang.

[0008] 本发明提供的金邦板表面处理工艺包括预热、喷涂硅烷水溶液、一次烘干、喷涂硅氧烷水溶液和二次烘干。 [0008] jinbang a surface treatment process of the present invention comprises preheating, spraying an aqueous solution of a silane, primary drying, and secondary drying an aqueous silicone coating.

[0009] 所述预热包括加热所述金邦板,使所述金邦板的板面温度在30°C-40°C,这利于吸收渗透; [0009] The preheating plate comprises heating the jinbang the temperature of the plate surface of the plate at GeIL 30 ° C-40 ° C, which facilitates the absorption permeation;

[0010] 本发明中所用的硅烷可以是市售的硅烷,优选道康宁公司的520,其是以N-辛基三乙氧基硅烷为主成分的混合物。 [0010] As used in the present invention, the silane can be a commercially available silane, preferably Dow Corning 520, which is a mixture of N- octyltriethoxysilane main component.

[0011] 所述硅烷水溶液的浓度是10wt%_15wt%,浓度过高不利于吸收渗透。 The concentration [0011] The aqueous silane solution is 10wt% _15wt%, the concentration of osmotic absorbent is not favorable.

[0012] 所述一次烘干包括将喷涂了硅烷水溶液的金邦板加热到60°C_80°C ;加热能使硅烷快速渗透,以留下一些表层便于下一步硅氧烷的渗透吸收。 [0012] The primary drying comprises spraying an aqueous solution of a silane jinbang plate is heated to 60 ° C_80 ° C; heating enables rapid penetration of the silane, leaving some skin to facilitate penetration of the next siloxane absorption.

[0013] 本发明中所用的硅氧烷可以是市售的硅氧烷,优选道康宁公司的IE6683,其是以八甲基环四硅氧烷为主成分的混合物。 [0013] As used in the present invention may be commercially available silicone silicone, preferably Dow Corning IE6683, which is a mixture of octamethyl cyclotetrasiloxane main component.

[0014] 硅氧烷水溶液的浓度为10wt%-15wt%,浓度过高不利于吸收渗透。 The concentration of [0014] silicone aqueous solution was 10wt% -15wt%, the concentration of osmotic absorbent is not favorable.

[0015] 所述二次烘干包括将喷涂了硅氧烷水溶液的所述金邦板加热到60°C_80°C。 The [0015] second drying comprises spraying a solution of the silicone jinbang plate is heated to 60 ° C_80 ° C.

[0016] 本工艺的优势: [0016] The advantage of this process:

[0017] 1、能保证金邦板表面的保护剂的耐候性和自清洁的荷叶效果。 [0017] 1, can deposit plate surface protective agent of the state of weather resistance and self-cleaning effect of the lotus leaf.

[0018] 2、喷涂硅烷水溶液后会在金邦板表面上形成保护层,不利于后续喷涂的吸收,在加热的情况下,硅氧烷也能很好地吸收。 [0018] 2, after spraying an aqueous solution of the silane will form a protective layer on the plate surface jinbang, not conducive to absorption of a subsequent coating, in the case of heating, the silicone can be well absorbed.

具体实施方式 detailed description

[0019]下面结合实施例对本发明做进一步详细说明。 [0019] The following embodiments in conjunction with embodiments of the present invention is described in further detail.
