背景技术 Background technique
国内现有镀膜工艺均采用在产品表面喷一层薄而亮的底漆，烘烤后置入真空室内，再进行蒸发镀膜。待解除真空之后，取出再在膜层上喷涂保护漆，以防止空气对膜层的氧化，且各个环节分开进行，使层与层之间不可避免要受到灰尘等污染，从而影响膜层质量，而且按这种工艺生产的产品附着力低，抗酸，抗氧化能力低，会造成膜层脱落导致产品寿命短。 The existing domestic coating process adopts spraying a layer of thin and bright primer on the surface of the product, putting it into a vacuum chamber after baking, and then performing evaporation coating. After the vacuum is released, take it out and spray protective paint on the film layer to prevent the air from oxidizing the film layer, and each link is carried out separately, so that the layers will inevitably be polluted by dust and the like, thus affecting the quality of the film layer. Moreover, the product produced by this process has low adhesion, acid resistance, and low oxidation resistance, which will cause the film layer to fall off and cause the product to have a short life. the

具体实施方式 Detailed ways
下面结合实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。 Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. the
一种兔底涂工艺，包括以下步骤：(1)对镀件表面进行高压离子清洗，并烘干，离子清洗是依靠离子体中活性粒子的“活化作用”达到去除物体表面污渍的目的；(2)对清洗后的镀件表面镀基膜；基膜主要是使产品有更好的附着力；基膜是在蒸发的低分子量有机材料之间，由于放电作用引起的反应，在镀件上淀积成薄膜。采用有机硅等离子重合SiOx，提高铝层的附着力和防腐蚀性能，作为膜层的衰减保护，以提高膜层的表面张力和硬度等，这样形成的薄膜均匀，没有针孔，附着力很强，具有很好的疏水性和耐化学腐蚀性能。(3)在真空室内对涂有基膜的镀件进行蒸发镀膜，真空度为3×10-2Pa；蒸发镀膜是指在真空条件下，用蒸发器加热蒸发物质使之汽化，蒸发粒子流直接射向基片并在基片上沉积形成固态薄膜；(4)在炉内对镀膜后的镀件附上保护膜，附保护膜时间为200s；保护膜则是为了防止空气对膜层的氧化。 A rabbit bottom coating process, comprising the following steps: (1) high-pressure ion cleaning is carried out on the surface of the plated parts, and drying, and the ion cleaning is to rely on the "activation" of active particles in the ion body to achieve the purpose of removing stains on the surface of objects; 2) Coating a base film on the surface of the cleaned plated parts; the base film is mainly to make the product have better adhesion; the base film is between the evaporated low molecular weight organic materials, due to the reaction caused by the discharge, on the plated deposited as a thin film. Silicone plasma is used to superimpose SiO x to improve the adhesion and anti-corrosion performance of the aluminum layer, as the attenuation protection of the film layer, to improve the surface tension and hardness of the film layer, so that the formed film is uniform, without pinholes, and the adhesion is very good Strong, good hydrophobicity and chemical resistance. (3) Evaporation coating is carried out on the plated parts coated with the base film in a vacuum chamber, the vacuum degree is 3×10 -2 Pa; evaporation coating refers to heating the evaporation material with an evaporator to vaporize it under vacuum conditions, and the evaporation particle flow Directly shoot to the substrate and deposit on the substrate to form a solid film; (4) attach a protective film to the plated parts in the furnace, and the time of attaching the protective film is 200s; the protective film is to prevent air from oxidizing the film layer .
按此工艺所镀产品通过了附着力试验、反射镜劣化试验及耐温试验。 The products plated according to this process have passed the adhesion test, mirror deterioration test and temperature resistance test. the
耐温试验：本试验由低温试验和高温试验组成，试验设备均符合GB2423.1和GB2423.2试验设备的有关要求。主要的试验结果如下： Temperature resistance test: This test consists of a low temperature test and a high temperature test, and the test equipment meets the relevant requirements of GB2423.1 and GB2423.2 test equipment. The main test results are as follows:
附着力试验：用锋利刀片(刀锋角度为15°～30°)在测试样本表面划10×10个1mm×1mm小网格，每一条划线深及油漆的底层；用毛刷将测试区域的碎片刷干净；用粘附力350g/cm2～400g/cm2的胶带(3M600号胶纸或等同)牢牢粘住被测试小网格，并用橡皮擦用力擦拭胶带，以加大胶带与被测区域的接触面积及力度；用手抓住胶带一端，在垂直方向(90°)迅速扯下胶纸，同一位置进行2次相同试验。我们曾随机抽取用此工艺所镀产品进行此项试验，结果均合格，划线边缘光滑，在划线的边缘及交叉点均无脱落现象。 Adhesion test: draw 10×10 small grids of 1mm×1mm on the surface of the test sample with a sharp blade (the blade angle is 15°～30°), and each line is as deep as the bottom layer of the paint; use a brush to wipe the surface of the test area Brush the debris clean; use adhesive tape (3M600 adhesive paper or equivalent) with an adhesion of 350g/cm 2 to 400g/cm 2 to firmly stick the small grid under test, and wipe the tape vigorously with an eraser to increase the contact between the tape and the substrate. Measure the contact area and strength of the area; grab one end of the tape with your hand, quickly tear off the tape in the vertical direction (90°), and perform the same test twice at the same position. We have randomly selected products plated with this process for this test, and the results are all qualified, the edge of the scribed line is smooth, and there is no shedding phenomenon at the edge and intersection of the scribed line.
反射镜劣化试验：把试样置于高温试验箱内1h，取出放置常温，然后逐项进行耐酸、碱、盐试验。我们对用此工艺所镀产品进行了此项试验，试验后检查试样无变形、腐蚀等缺陷。 Mirror deterioration test: Put the sample in the high-temperature test chamber for 1 hour, take it out and place it at room temperature, and then carry out acid, alkali and salt resistance tests one by one.
