Embodiment 1

[0017] Coat the surface of the aluminum-plastic plate with a thickness of 4mm with adhesive and dry it, and then put it on the PVC color pattern film with a thickness of 0.3mm at 200°C, 6kg / m 3 Roll down to obtain the aluminum-plastic panel 1 with PVC color pattern finish. The binder is composed of a colloid and a curing agent with a mass ratio of 3:1, and the mass percentages of the components of the colloid part are: polyether 10%, polyester 35%, phthalic anhydride 4.8%, MDI 7%, cyclic Hexane 20%, the balance is ethyl ester. The curing agent is a mixture of 35% by mass of TDI, 18% by mass of MDI, 18% by mass of trimethylolpropane and 29% by mass of ethyl ester.

Embodiment 2

[0019] Coat the surface of the aluminum-plastic plate with a thickness of 2mm with adhesive and dry it, and then put it on the PVC color pattern film with a thickness of 0.1mm at 160°C, 4kg / m 3 The lower roll press obtains the aluminum-plastic panel 2 with PVC color grain finish. The adhesive is composed of a colloid and a curing agent with a mass ratio of 4:1, and the mass percentages of the components of the colloid part are: polyether 12%, polyester 30%, phthalic anhydride 5.5%, MDI 8%, cyclic 10% hexane, the balance is ethyl ester. The curing agent is a mixture of 38% by mass of TDI, 10% by mass of MDI, 10% by mass of trimethylolpropane and 42% by mass of ethyl ester.

Embodiment 3

[0021] Coat the surface of the aluminum-plastic plate with a thickness of 3mm with adhesive, dry it, and then put it on the PVC color pattern film with a thickness of 0.1mm at 180°C, 4kg / m 3 The lower roll press obtains the aluminum-plastic panel 3 with PVC color grain finish. The binder is composed of a colloid and a curing agent with a mass ratio of 4:1, and the mass percentages of the components of the colloid part are: polyether 11%, polyester 32%, phthalic anhydride 5%, MDI 7.5% , Cyclohexane 15%, the balance is ethyl ester. The curing agent is a mixture of 30% by mass of TDI, 13% by mass of MDI, 12% by mass of trimethylolpropane and 45% by mass of ethyl ester.

Abstract

The invention provides a preparation method for a plastic-aluminum plate with a PVC color-pattern facing. The method comprises the following steps: coating the surface of a plastic-aluminum plate with a binder; then carrying out drying; and subjecting the dried plastic-aluminum plate and a PVC color-pattern film to rolling at a temperature of 160 to 200 DEG C so as to obtain the plastic-aluminum plate with the PVC color-pattern facing. The invention also provides the plastic-aluminum plate with the PVC color-pattern facing prepared by using the method. The plastic-aluminum plate with the PVC color-pattern facing prepared by using the method has rich and colorful appearance and good fire resistance, corrosion resistance and thermal insulation performance. Moreover, the plastic-aluminum plate with the PVC color-pattern facing appears to be smooth and beautiful; the PVC color-pattern film is tightly bonded with the plastic-aluminum plate, hardly falls off and has good quality, so good practicality is realized.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a PVC color-patterned aluminum-plastic panel and a preparation method thereof. Background technique [0002] After more than ten years of development in the aluminum-plastic panel industry, it has now become one of the interior and exterior walls of large-scale buildings, landmark buildings and high-end residential buildings in China. The technology is mature, the production scale is large, the construction is simple, the appearance is diverse, and the market prospect is booming. Estimate. [0003] With the development of the times, the pace of urban construction has made great strides, and the consumption level of residents has risen in step with the taste of life. The traditional simple appearance, single color, and boring aluminum-plastic panels have been difficult to meet people's needs for high-quality and comfortable life. People look forward to a warm and leis...
