Description
Technical Field
The invention relates to the technical field of preparation and application of acrylate materials, in particular to a composition for preparing a light-transmitting scattering acrylate product, the light-transmitting scattering acrylate product and a preparation method thereof.
Background
Acrylic polymers have excellent optical transparency due to their molecular structure tailorability and general amorphous noncrystalline properties, and have a wide range of applications from rubbers to plastics. In addition, the coating has the advantages of stability, weather resistance, good film forming property, adhesion, corrosion resistance, chemical resistance and the like. As a transparent material, organic glass (polymethyl methacrylate) has been widely used in many fields; the optical cement of acrylic ester is widely used in electronic products. Besides the extremely transparent articles, the semi-transparency and the surface texture are important characteristics of a plurality of daily articles and are also targets which are widely pursued by people.
In the aspect of material preparation, various fillers are added to improve the material performance and reduce the material cost. On some plastic products, the filler can even reach 80%, which greatly exceeds the amount of the body.
Acrylic polymers can also be reduced in cost by filling the filler in large amounts, however, even small amounts of conventional fillers completely sacrifice the light transmission characteristics of the acrylates. Even if the transparent powder on the market is applied to unsaturated resin, epoxy resin and the like of paint, the transparency of the product can be completely lost when the transparent powder is applied to the acrylate polymer.
Moreover, for the current environment-friendly and energy-saving UV curing technology, the product thickness is often limited due to the limitation of the irradiation depth of UV light; high fill further reduces the depth of UV light exposure. At high loadings, the cure tends to be only surface cure, with the glue migrating to the surface leaving a loose center of the fill powder, making thick film article preparation impossible.
Disclosure of Invention
The invention mainly aims to provide a composition for preparing an acrylate product, the acrylate product and a preparation method thereof, wherein the composition and the product can reduce the cost of the acrylate polymer and can ensure that the acrylate product has good light transmission scattering property and frosting effect; and the problem that the large-thickness acrylate product cannot be prepared by UV curing during high filling is solved.
In order to achieve the above object, according to one aspect of the present invention, there is provided a composition for preparing a light-scattering acrylate-based article, the composition comprising the following components in percentage by weight:
wherein, the light-transmitting scattering filler is an inorganic filler which has a refractive index close to that of a polymer formed by an acrylate prepolymer.
If transparent powder on the market is added into an acrylate product, the transparent powder is applied to an acrylate polymer because the transparent powder is mainly applied to unsaturated resin, epoxy resin and the like of paint and coating, so that the transparency of the product is completely lost. According to the invention, the inorganic filler with the refractive index close to that of the polymer formed by the acrylate prepolymer is added into the acrylate composition as the light-transmitting scattering filler, and the light-transmitting scattering filler can be well matched with the acrylate prepolymer, so that the production cost of the acrylate product can be greatly reduced, the light transmittance of the acrylate product cannot be greatly influenced, and various acrylate products with good light-transmitting scattering property and certain frosting effect can be obtained by adopting the composition.
Further, the light-transmitting scattering filler is one or more of sodium sulfate decahydrate, aluminum potassium sulfate dodecahydrate, magnesium sulfate heptahydrate, sodium acetate hydrate, sodium borate hydrate, aluminum sulfate, anhydrous sodium sulfate, potassium dihydrogen phosphate, sodium bicarbonate, anhydrous borax, sodium silicate, basic magnesium sulfate whisker, calcium sulfate hydrate, silica, and quartz powder. The light-transmitting scattering filler with the refractive index close to that of the polymer can be selected according to the specific type of the acrylate prepolymer so as to ensure that the product has the light transmittance as high as possible.
Further, the initiator is a thermal initiator or a photoinitiator; the auxiliary additive is one or more of a dispersant, a coupling agent, an anti-aging agent, an internal release agent, an anti-settling agent and a pigment; the acrylate prepolymer is a prepolymer mainly taking isooctyl acrylate and acrylic acid as monomers, or a polymethyl methacrylate prepolymer. Specifically, when an acrylate prepolymer taking isooctyl acrylate and acrylic acid as monomers is adopted, a photoinitiator is correspondingly adopted; when using a polymethyl methacrylate prepolymer, a thermal initiator is correspondingly used.
The prepolymer (pressure-sensitive adhesive prepolymer) taking isooctyl acrylate and acrylic acid as monomers is prepared by uniformly mixing isooctyl acrylate, acrylic acid and a photoinitiator in a reaction kettle, irradiating for a certain time to reach specific viscosity by UV lamp light, and introducing air to terminate polymerization. The polymethyl methacrylate prepolymer is prepared by adopting a methyl methacrylate monomer and azodiisobutyronitrile as an initiator, polymerizing at 70 ℃ to a certain viscosity and then terminating the polymerization.

The refractive index of the traditional transparent powder filler is close to that of unsaturated resin, epoxy resin and the like, and is about 1.55. There is no clear effect for acrylate glues with a refractive index around 1.43. Moreover, for UV-cured acrylate glue, the addition of unmatched large amounts of fillers tends to limit the thickness of the glue film to below 50 microns or to present serious poor curing problems.
Inorganic filler with a refractive index similar to that of a polymer formed by isooctyl acrylate prepolymer is added into the isooctyl acrylate prepolymer and the acrylic prepolymer to serve as a light-transmitting scattering filler; the pressure-sensitive adhesive tape with high light transmittance and good performance can be prepared under the conditions of high filling and large thickness (3 mm).

Further, the light-transmitting scattering filler is one or more of sodium sulfate decahydrate, aluminum potassium sulfate dodecahydrate, magnesium sulfate heptahydrate, sodium acetate hydrate, sodium borate hydrate, aluminum sulfate, anhydrous sodium sulfate, potassium dihydrogen phosphate, sodium bicarbonate, anhydrous borax, sodium silicate, basic magnesium sulfate whisker, calcium sulfate hydrate, silica, and quartz powder.
Further, one or more of magnesium sulfate heptahydrate, aluminum potassium sulfate dodecahydrate, sodium sulfate decahydrate, anhydrous sodium sulfate, and anhydrous borax are preferably used as the light-transmitting scattering filler. The refractive index of the copolymer is closer to that of a polymer formed by isooctyl acrylate and acrylic acid prepolymer.
Further, the auxiliary additive is one or more of a dispersing agent, a coupling agent, an anti-aging agent, an internal mold release agent, an anti-settling agent and a pigment.

According to another aspect of the present invention, there is provided a light-transmitting and light-scattering organic glass obtained by blending, extruding or casting and molding a composition for preparing a light-transmitting and light-scattering acrylic product, wherein the composition comprises the following components by weight:
wherein, the light-transmitting scattering filler is an inorganic filler with the refractive index close to that of polymethyl methacrylate.
Further, the light-transmitting scattering filler is one or more of aluminum sulfate, anhydrous sodium sulfate, potassium dihydrogen phosphate, anhydrous borax, sodium silicate, basic magnesium sulfate whisker and hydrated calcium sulfate; the auxiliary additive is one or more of a dispersant, a coupling agent, an anti-aging agent, an internal release agent, an anti-settling agent and a pigment.
