Problems solved by technology

The existing refrigerator shell components are mainly sheet metal parts, which have the disadvantages of heavy weight and high production cost. Therefore, there is a need for a material that can replace the refrigerator shell sheet metal parts
Due to its good structural strength, flame retardancy and aging resistance, PVC board can be used to replace the refrigerator back panel of the refrigerator shell assembly, but the existing PVC board has the problem of poor appearance. A layer of aluminum foil is compounded on the surface to improve the appearance of the PVC board
However, since the linear thermal expansion coefficient of the PVC board is 80×10-6m / m·℃, the linear thermal expansion coefficient of the aluminum foil is 23×10 -6 There is a large difference in m / m·℃, which leads to the problem that the aluminum foil will fall off and the PVC board will warp due to the thermal expansion and contraction after the PVC board is laminated with the aluminum foil, making the PVC board after the composite aluminum foil unusable

Embodiment 1

[0026] Such as figure 1 As shown, the PVC aluminum foil plate with flame-retardant function of the present invention includes a PVC substrate 1, and an aluminum foil 3 is bonded to the surface of one side of the PVC substrate 1, and the linear thermal expansion coefficient of the aluminum foil 3 is 23×10 -6 m / m·°C, the aluminum foil 3 is bonded on the PVC substrate 1 through the hot melt adhesive 2, and the hot melt adhesive 2 is polyester hot melt adhesive. In order to enhance the bonding strength between the aluminum foil 3 and the PVC substrate 1 , the PVC substrate 1 is also embossed with embossed patterns.

[0027] The internal lubricant that the present invention uses is modified butyl stearate, and the modification method of modified butyl stearate is: natural kapok fiber is under nitrogen atmosphere, 200 ℃ of carbonization 6 hours, obtain carbonized kapok fiber, then Dissolve 30 parts of butyl stearate in 200 parts of ethanol, then add 12 parts of carbonized kapok fib...

Embodiment 2

[0031] The difference with Example 1 is that the weight ratio of PVC sheet material, calcium zinc stabilizer, reinforcing agent mbs resin, toughening agent chlorinated polyethylene, external lubricant polyethylene wax, internal lubricant and flame retardant magnesium oxide is 120:5.3:1.7:2.3:2.6:3.4:8.7.

Abstract

The invention discloses a PVC aluminum foil plate with a flame-retardant function and a processing technology thereof. The PVC aluminum foil plate comprises a PVC base plate, embossed patterns are arranged on the PVC base plate, aluminum foil is bonded to the surface of one side of the PVC base plate through a hot melt adhesive, and the difference between the linear thermal expansion coefficient of the PVC base plate and the linear thermal expansion coefficient of the aluminum foil is smaller than 8*10 <-6>m / m.DEG C. According to the processing technology, the defects in the prior art are overcome, the PVC aluminum foil plate produced through the processing technology is free of bulging and debonding phenomena, the warping degree of the produced PVC aluminum foil plate is small, and the PVC aluminum foil plate can be applied to a rear back plate of a refrigerator.

Description

technical field [0001] The invention relates to the technical field of PVC aluminum foil boards, in particular to a PVC aluminum foil board with a flame-retardant function and a processing technology thereof. Background technique [0002] PVC board has high structural strength, heat resistance and flame retardancy, and is widely used in construction and packaging materials. Existing refrigerator shell components are mainly sheet metal parts, which have the disadvantages of heavy weight and high production cost. Therefore, there is a need for a material that can replace the refrigerator shell sheet metal parts. Due to its good structural strength, flame retardancy and aging resistance, PVC board can be used to replace the refrigerator back panel of the refrigerator shell assembly, but the existing PVC board has the problem of poor appearance. A layer of aluminum foil is compounded on the surface to improve the appearance of the PVC board. However, since the linear thermal e...
