Description

溶剂型脱漆剂及其应用和工件脱漆方法  Solvent-based paint stripper and application thereof and workpiece stripping method 技术领域Technical field
本发明涉及表面处理技术领域，具体涉及一种溶剂型脱漆剂及其应用和工件脱漆方法。  The invention relates to the technical field of surface treatment, in particular to a solvent-based paint stripper and its application and a paint stripping method.
背景技术Background technique
为提高产品表面性能或者外观，通常对工件表面处理技术。例如，铝、铁及其合金的表面处理工艺深入各行各业中。而且，大多数工作在进行表面处理前还需要经过预处理，例如，进行清洗，除污除油，对于一些特定工件还需要进行脱漆处理。例如，对于一些喷漆不良漆层，需要重新喷涂漆层，那么需要先退除漆层，再重新喷漆。 In order to improve the surface properties or appearance of the product, the surface treatment technology of the workpiece is usually used. For example, the surface treatment processes of aluminum, iron and their alloys go deep into all walks of life. Moreover, most of the work needs to be pre-treated before surface treatment, for example, cleaning, decontamination and degreasing, and stripping treatment for some specific workpieces. For example, for some paint finishes that need to be repainted, the paint layer must be removed and repainted.
脱漆剂通常利用溶剂分子的渗透力，在活化剂和其他成分的作用下，使交联的高分子材料溶胀、软化、起皱和溶解，脱离基材表面而剥落下来。一些脱漆剂还添加有浓硫酸，利用浓硫酸的强腐蚀性，加速脱漆或提高脱漆效果。然而，这种脱漆剂对基材腐蚀较大，有时甚至会给基材造成难以恢复的损伤，且使用时通常产生热量，具有挥发性气味，难以满足安全环保的要求。 The paint stripper usually utilizes the permeation force of the solvent molecules to cause the crosslinked polymer material to swell, soften, wrinkle and dissolve under the action of the activator and other components, and peel off from the surface of the substrate. Some paint strippers are also added with concentrated sulfuric acid, which utilizes the strong corrosiveness of concentrated sulfuric acid to accelerate the stripping or improve the stripping effect. However, such paint stripping agents are highly corrosive to the substrate, and sometimes cause irreparable damage to the substrate, and usually generate heat when used, have a volatile odor, and are difficult to meet safety and environmental protection requirements.
技术问题technical problem
有鉴于此，提供一种安全有效且对基材腐蚀小的溶剂型脱漆剂及其应用和工件脱漆方法。  In view of this, a solvent-based paint remover which is safe and effective and has low corrosion to a substrate, and an application thereof and a paint stripping method of the workpiece are provided.

以下将结合具体实施例对本发明进行详细说明。 The invention will now be described in detail in connection with specific embodiments.
本实施例提供一种溶剂型脱漆剂，其包括按照重量份数配比的下列成分： This embodiment provides a solvent-based paint remover comprising the following components in parts by weight:
二氯甲烷 262-550 Dichloromethane 262-550

The part by weight of phenol is 33-66, more preferably 33-50. The solvent-based paint remover is preferably a colorless, odorless liquid. The stripping agent stripping mechanism of the present embodiment is: methylene chloride and a coating are dissolved, phenol is used as an auxiliary agent to promote dissolution of the coating layer and the solvent, and formic acid and hydrofluoric acid are reacted with the metal to separate the coating layer from the substrate.
上述溶剂型脱漆剂主要用于金属工件的表面漆层或塑层的脱除。金属工件可以是铝材，铁件，锌合金等，漆层可以是各类电泳漆、烤漆等，还可以是喷塑涂层。以应用于铝材工件为例，具体脱漆方法包括以下步骤：将剥漆液倒入脱漆槽中，为了减少气体的逸出可以采用水封的方式（即在槽液中倒入少量水，由于比重关系，自来水会漂在溶液上面），然后将带漆工件浸入本品中，较厚的漆膜可先划破至金属基体再浸入工作液中。待工件表面的涂层起泡或起皱后，取出，将工件放入清水中冲洗或漂洗，涂层便会干净彻底地脱离工件。视漆层种类、厚度及工件状况，剥漆时间为 1 至 10 分钟。 The above solvent-based paint stripping agent is mainly used for the removal of the surface paint layer or the plastic layer of the metal workpiece. The metal workpiece can be aluminum, iron, zinc alloy, etc. The lacquer layer can be various types of electrophoretic paint, baking varnish, etc., or can be spray-coated. For example, the aluminum stripping method includes the following steps: pouring the stripping liquid into the stripping tank, and in order to reduce the escape of the gas, a water seal can be used (ie, a small amount of water is poured into the bath). Because of the specific gravity, the tap water will float on the solution, and then the lacquered workpiece will be immersed in the product. The thicker paint film can be scratched to the metal substrate and then immersed in the working fluid. After the coating on the surface of the workpiece is foamed or wrinkled, it is taken out, and the workpiece is washed or rinsed in clean water, and the coating is clean and completely separated from the workpiece. Depending on the type of paint layer, the thickness and the condition of the workpiece, the stripping time is 1 to 10 minutes.
