Abstract
The utility model discloses a color PP-PET film coated steel sheet which comprises a metal substrate, and is characterized in that a chemical coating and a PP-PET film layer are arranged on one side of the metal substrate in sequence. The color PP-PET film coated steel sheet has the advantages that the PP-PET film layer is adhered onto the metal substrate, and the PP-PET film after being subjected to high-temperature melt can be closely adhered with the steel sheet, so that the color PP-PET film coated steel sheet has the advantages of high peeling strength, cup drawing of 9 mm, durability better than that of a PVC coated sheet, simple manufacturing method for products, low cost and improved finished product ratio, and is more environmentally friendly.
Description
Technical field
The utility model belongs to the clad steel plate Material Field, particularly relates to a kind of PP-PET film colorful covering membrane steel plate.
Background technology
Appliance shell often adopts the colorful covering membrane steel plate at present, the colorful covering membrane steel plate is a kind of advanced composite material (ACM), as substrate take cold-rolled steel sheet and galvanized steel plain sheet or aluminium sheet, process through surperficial degreasing, cleaning, chemical conversion, cover the product that one deck PVC film is made with glue, product has the characteristics such as production efficiency is high, attractive in appearance, Corrosion Protection is good, and practicality is very strong.
But the PVC film of existing colorful covering membrane steel plate (PVC film coated plate) mainly is to adopt glue to cover on metal substrate, and the PVC film contains the composition of not environmental protection, and cost is higher, and the applying defective tightness is lasting.
The utility model content
Based on this, the purpose of this utility model provides a kind of PP-PET film colorful covering membrane steel plate.
Concrete technical scheme is as follows:
A kind of PP-PET film colorful covering membrane steel plate comprises metal substrate, and a side of described metal substrate is being provided with coating, PP-PET rete successively.The PP-PET film through high temperature melt can with the steel plate close adhesion, peel strength can reach cupping 9mm, durability is better than gluing product.
Among embodiment, describedization coating is that thickness is the netted chemical conversion rete of Chrome-free of 1-2 μ m therein.The design of changing coating has strengthened the corrosion resistance of metal substrate, has also improved the adhesive force of metal substrate simultaneously.
Among embodiment, described PP-PET rete is the figuratum high temperature resistance polyester film of printing therein.The PP-PET film has excellent physical property, chemical property and dimensional stability, the transparency, recuperability, and the surface pattern that can be beautifully printed is a kind of environment-friendly novel material of alternative PVC film.
Among embodiment, the opposite side of described metal substrate is being provided with coating, back of the body enamelled coating successively therein.Change corrosion resistance and adhesive force that coating can strengthen metal substrate, back of the body enamelled coating can further strengthen the corrosion resistance of metal substrate, has also improved the flatness of metal substrate simultaneously.
Among embodiment, also be provided with protective film on the described PP-PET rete therein.Protective film can prevent in transit or other situation lower steel plates by scratch, pollution.
Among embodiment, described metal substrate is cold-rolled steel sheet or galvanized steel plain sheet therein.
The utility model has the advantages that:
PP-PET film colorful covering membrane steel plate of the present utility model, covered the PP-PET rete at metal substrate, the PP-PET film through high temperature melt can with the steel plate close adhesion, peel strength is high, can reach cupping 9mm, and durability is better than PVC film coated plate product, production is simple, cost is lower, has improved the yield rate of product, and more environmental protection.

The specific embodiment
By the following examples the utility model is further elaborated.
With reference to figure 1, the described PP-PET film of the present embodiment colorful covering membrane steel plate comprises metal substrate 200, and a side of described metal substrate 200 is being provided with coating 201, PP-PET rete 202 successively; The opposite side of described metal substrate 200 is being provided with coating 201, back of the body enamelled coating 203 successively.
Described PP-PET rete 204 is the figuratum high temperature resistance polyester film of printing.The PP-PET film has excellent physical property, chemical property and dimensional stability, the transparency, recuperability, and the surface pattern that can be beautifully printed is a kind of environment-friendly novel material of alternative PVC film.The PP-PET film through high temperature melt can with the steel plate close adhesion, peel strength can reach cupping 9mm, durability is better than gluing product.
Described PP-PET rete 204 is provided with protective film 205, protective film 205 can prevent in transit or other situation lower steel plates by scratch, pollution.
Described metal substrate 200 is cold-rolled steel sheet or galvanized steel plain sheet.
The preparation method of the described PP film of the present embodiment colorful covering membrane steel plate is as follows:
(1) clean metal substrate (cold-rolled steel sheet or galvanized steel plain sheet) is removed antirust oil, rust staining and dust that metallic substrate surfaces is adhered to, then oven dry.
(2) 2 sides at metal substrate all apply immersion coating, oven dry, formationization coating; Described immersion coating is the netted chemical composition coating of a kind of Chrome-free, and its thickness is 1 μ m-2 μ m, can increase corrosion resistance and the adhesive force of steel plate.
(3) steel plate after step (2) is processed through immersion coating is heated to about 220 ℃, covers one deck PP-PET film at the change coating surface of metal substrate one side, forms the PP-PET rete; This PP-PET rete is the figuratum high temperature resistance polyester film of printing.The PP-PET film has excellent physical property, chemical property and dimensional stability, the transparency, recuperability, and the surface pattern that can be beautifully printed is a kind of environment-friendly novel material of alternative PVC film.The PP-PET film through high temperature melt can with the steel plate close adhesion, peel strength can reach cupping 9mm, durability is better than gluing product.
The surface of the PP-PET layer that (4) obtains in step (3) applies layer protecting film, forms protective film; Can prevent that product finish paint in the processes such as transportation from being scraped and polluting.
(5) the change coating surface at the metal substrate opposite side applies one deck back of the body lacquer, and oven dry forms back of the body enamelled coating.
Obtain the described PP-PET film of the present embodiment colorful covering membrane steel plate by above-mentioned steps.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
