Description
Technical Field
The invention belongs to the technical field of corrosion prevention, and particularly relates to preparation of a high-adhesion water-based vinylidene chloride metal paint.
Background
The metal is subject to chemical, electrochemical or physical interaction with the environment medium in which the metal is located, so that the metal is deteriorated and deteriorated, namely metal corrosion, which is quite common. From a thermodynamic point of view, the corrosion of metals is generally a spontaneous process, except for very few precious metals (Au, Pt, etc.). It has been recognized that the metals used are rarely damaged by simple mechanical factors (such as tension, compression, impact, fatigue, fracture and abrasion) or other physical factors (such as thermal energy, light energy, etc.), and that the damage to most metallic materials is related to their corrosion factors, and therefore corrosion of metallic materials has become a significant problem that is not negligible today.
The epoxy resin has a large number of hydroxyl groups, can generate strong binding power with a metal substrate, and the thermosetting resin with the performance after the epoxy resin and the curing agent are crosslinked has good corrosion resistance.
The water-based vinylidene chloride copolymer emulsion does not contain organic solvent, has no pollution to the environment when being applied to the field of water-based paint, and does not cause harm to human bodies. The aqueous polyvinylidene chloride resin applied to the field of metal corrosion resistance has two basic performances, namely good barrier performance and strong adhesive force. The polyvinylidene chloride resin with high VDC content and better barrier property has poor emulsion stability and film forming property, low adhesive force with metal and easy shedding.
Compared with the waterborne epoxy resin, the waterborne PVDC coating omits the use of zinc powder paint in the construction process due to the excellent barrier property of PVDC, so that the cost of the whole coating is reduced.
Vinylidene chloride resin has good barrier properties, but has poor adhesion to metal surfaces. The water-based epoxy resin has good adhesive force with a metal base material, but the epoxy resin with strong corrosion resistance is generally double-component, and in the actual application process, the double-component coating has high requirements on construction technology and equipment, so that the application of the double-component coating is limited.
Patent document 1 provides an aqueous paint, a preparation method and an application thereof, wherein the aqueous resin comprises 30-50 parts by weight of aqueous acrylic acid modified epoxy emulsion, 2-15 parts by weight of silica sol and 5-10 parts by weight of polyvinylidene chloride emulsion, and the film forming substance in the invention also uses the compounding of aqueous vinylidene chloride and epoxy resin, but the content of the vinylidene chloride emulsion is less, and the epoxy resin is acrylic acid modified emulsion and is a main component, and the content of the vinylidene chloride emulsion is lower, so that excellent barrier property cannot be achieved;
patent document 2 discloses a water-based single-component rust-bearing construction steel structure primer and a preparation method and application thereof. Wherein the film-forming substance is high-solid water-based modified epoxy ester resin and water-based vinylidene chloride modified acrylic resin. The waterborne vinylidene chloride modified acrylic resin mainly comprises acrylic acid, and compared with macromolecular waterborne epoxy resin, the waterborne epoxy ester resin has smaller molecular weight and weaker relative corrosion resistance.
The polyvinylidene chloride metal protective paint is prepared by using polyvinylidene chloride emulsion and aqueous single-component epoxy resin as main film forming substances, and has high adhesive force and no influence on high barrier property.
