Abstract

The invention discloses a metal template coating which is composed of, by weight, 70-90% of main resin, 3-10% of diluent, 3-10% of pigment and filler, 1-5% of auxiliary and 1-5% of photosensitive agent. The main resin is selected from one or multiple of aliphatic polyurethane acrylate, acrylate or aromatic methyl semi-acrylate, the diluent is selected from one or multiple of isobornyl acrylate, 1,6-hexanediol diacrylate or tripropylene glycol diacrylate, the pigment and filler comprises 20-30% of zinc stearate, 20-30% of bentonite, 20-30% of calcium carbonate and 20-30% of talcum powder, theauxiliary is selected from one or multiple of polysiloxane, unsaturated polyamide and hydroxyl acid salt or propylene glycol methyl ether, and the photosensitive agent is selected from one or multipleof 1-hydroxy cyclohexylphenyl ketone, 2-isopropyl thioxanthone or 2-benzyl-dimethyl amino-1-(4-morpholine phenyl) butanone.The preparation method does not need a curing agent, and momentary drying within 10s can be realized through ultraviolet curing. The metal template coating is powerful in bonding with an aluminum alloy template and less prone to shedding.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a metal template coating, a preparation method thereof, a coating method and a coating production line. Background technique [0002] The development of metal formwork has led to a "revolution" in energy saving and emission reduction of building formwork. At present, the advantages of metal formwork for construction are as follows: 1. Short construction period: the aluminum alloy building formwork system is a quick-release formwork system, and the normal construction of a set of formwork can reach one floor in four or five days, which greatly saves the management cost of the construction unit; 2. Many times of repeated use and low average cost of use: the aluminum alloy building metal formwork system uses aluminum alloy profiles formed by integral extrusion as raw materials (6063-T6 or 6061-T6), and a set of formwork can be turned over and used 300-500 times for standard cons...
