particular to a plastic masterbatch for heat-insulating and anticorrosive hot-melt acrylic
color steel plate, a heat-insulating and anticorrosive hot-melt acrylic color steel plate and
their preparation methods.
[0002] During use, color steel plates are often exposed to the scorching sun. High
temperature causes paint and other adhesion layers of the color steel plate to crack and fall
off, and rain and other corrosive substances corrode the surface of the color steel plate,
resulting in rust on the surface of the color steel plate. Color steel plates are unable to
work effectively as a result of the decrease of its strength. At present, the surface of the
color steel plates on the market is mostly shield by aluminum alloy film, modified
polyester coating, or fluorocarbon coating. The film or coating is very thin and not
cost-effective.
[0003] Based on the above situation, the objective of the invention is to provide a
plastic masterbatch for heat-insulating and anticorrosive hot-melt acrylic color steel plate,

[0020] 7 parts of a porous insulation filler,
[0021] 3.2 parts of an antioxidant, and
[0022] 3.3 parts of an anti-ultraviolet agent.
[0023] Preferably, the vinyl ester glass flake mortar is a mixture of
high-temperature vinyl ester glass flake mortar and medium-temperature vinyl ester glass
flake mortar.
[0024] Preferably, the mass ratio of the high-temperature vinyl ester glass flake
mortar to the medium-temperature vinyl ester glass flake mortar is 1:(1.6-1.8).

masterbatch for heat-insulating and anticorrosive hot-melt acrylic color steel plate,
comprising:
[0030] weighing the following raw materials in parts by weight: polymethyl
methacrylate, ethylene-methyl methacrylate copolymer, vinyl acetate-methyl methacrylate
block copolymer, bismaleimide modified phenolic epoxy resin, vinyl ester glass flake

[0035] Compared with the prior art, the present invention has the following
advantages and beneficial effects:
[0036] According to the plastic masterbatch for heat-insulating and anticorrosive
hot-melt acrylic color steel plate of the invention, by selecting raw materials carefully and
optimizing the content of each raw material, polymethyl methacrylate, ethylene-methyl
methacrylate copolymer, vinyl acetate-methyl methacrylate block copolymer,
bismaleimide modified phenolic epoxy resin, vinyl ester glass flake mortar, a porous
insulation filler, an antioxidant, and an anti-ultraviolet agent are selected in an appropriate
ratio; they not only give full play to their respective advantages, but also complement each
other and promote each other. The ethylene-methyl methacrylate copolymer has a good
compatibility with other components, and can increase the fluidity of the raw materials
and enhance the binding force between the plastic layer and the color steel plate. The most
important thing is that the ethylene-methyl methacrylate copolymer can make
high-temperature vinyl ester glass flake mortar, medium-temperature vinyl ester glass
flake mortar, nanoporous graphene and microporous calcium silicate having good
dispersion and compatibility in the raw material system of the invention, and ensuring that
the plastic layer has good comprehensive performance. The vinyl acetate-methyl methacrylate block copolymer mainly plays a role in enhancing the binding force between the plastic layer and the color steel plate. The bismaleimide modified phenolic epoxy resin mainly plays a role to further improve the corrosion resistance of the plastic layer and further enhance the binding force between the plastic layer and the color steel plate. The plastic layer made of the plastic masterbatch has low thermal conductivity and good thermal insulation performance; it also has excellent salt spray resistance and excellent corrosion resistance, and can be soaked for more than 9536 hours without rust, blistering, or falling off.
[0037] In addition, the heat-insulating and anticorrosive hot-melt acrylic color
steel plate has high corrosion resistance , and can be used as metal building envelope
material in the industries like chemical industry, foundry industry, coal industry, ceramic
industry and food deep processing industry. The heat-insulating and anticorrosive hot-melt
acrylic color steel plate is cost-effective. The thickness of the plastic layer can reach
110-160m, and the plastic layer can be more artistic by rolling out concave and convex
patterns during its formation.
[0038] The preparation method of the invention has simple process and simple
operation, and saves manpower and equipment costs.
[0039] In order to enable those skilled in the art to better understand the technical
solutions of the invention, the preferred embodiments of the invention will be described

[00124] It can be seen from the above table that the heat-insulating and
anticorrosive hot-melt acrylic plastic layer made of the plastic masterbatch for
heat-insulating and anticorrosive hot-melt acrylic color steel plate has the following
advantages: the plastic layer has low thermal conductivity and good thermal insulation
performance; it also has excellent salt spray resistance and excellent corrosion resistance,
and can be soaked for more than 9536 hours without rust, blistering, or falling off.
[00125] The above are only the preferred embodiments of the invention. It should
be noted that the above preferred embodiments should not be regarded as limiting the
invention, and the protection scope of the invention should be subject to the scope defined by the claims. For those of ordinary skill in the art, multiple improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as falling within the scope of the invention.
