Detailed Description
For purposes of the following detailed description, it is to be understood that the invention may assume various alternative variations and step sequences, except where expressly specified to the contrary. Moreover, other than in any operating examples, or where otherwise indicated, all numbers expressing, for example, quantities of ingredients used in the specification and claims are to be understood as being modified in all instances by the term "about". Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
When a range of values is disclosed herein, the range is considered to be continuous and includes both the minimum and maximum values of the range, as well as each value between such minimum and maximum values. Further, when a range refers to an integer, each integer between the minimum and maximum values of the range is included. Further, when multiple range-describing features or characteristics are provided, the ranges may be combined. In other words, unless otherwise indicated, all ranges disclosed herein are to be understood to encompass any and all subranges subsumed therein. For example, a stated range from "1 to 10" should be considered to include any and all subranges between the minimum value of 1 and the maximum value of 10. Exemplary subranges of the range 1 to 10 include, but are not limited to, 1 to 6.1, 3.5 to 7.8, 5.5 to 10, and the like.
In order to solve the technical problems, the first aspect of the invention provides a decorative material, which comprises, by weight, 30-60 parts of resin, 1-10 parts of reinforcing filler, 2-8 parts of plasticizer, 1-10 parts of flame retardant, 0.5-2 parts of ultraviolet absorber, 0.1-1 part of coupling agent, 0.5-1.5 parts of hindered amine light stabilizer and 1-2 parts of foaming agent, wherein the reinforcing filler is glass fiber, and the diameter of the glass fiber is 7-24 μm.
As a preferred technical scheme, the diameter of the glass fiber is 7-11 μm.
The glass fiber is an inorganic non-metallic material with excellent performance, has various varieties and has the advantages of good insulativity, strong heat resistance, good corrosion resistance and high mechanical strength. The mechanical strength of the whole material can be improved by adding a certain amount of glass fibers into the decorative material, but when the diameter of the glass fibers is too large, the problem of compatibility between the glass fibers and resin is serious, and the mechanical property of the decorative material can be influenced. The inventors have found that when glass fibers having a diameter of 7 to 11 μm are selected, the decorative material has both good mechanical strength and good smoothness and compatibility.
As a preferable technical solution, the resin is a mixture of phenolic resin and polyurethane resin, and the mass ratio between the phenolic resin and the polyurethane resin is 1: (1.5-2).
Although the strength of the glass fiber is high, the toughness of the whole material is reduced to a certain degree, and the inventor uses certain phenolic resin and polyurethane resin for compounding, so that the whole decorative material has good toughness and good strength.
As a preferable technical scheme, the coupling agent is at least one selected from silane coupling agent, phosphate coupling agent and phthalate coupling agent.
As a preferred technical scheme, the coupling agent is a silane coupling agent.
The inventor adds a certain amount of silane coupling agent to improve the compatibility between the glass fiber and the phenolic resin and the polyurethane resin, and further improve the uniformity of the mechanical property of the whole material.
As a preferable embodiment, the plasticizer is at least one selected from the group consisting of dihexyl phthalate, di-n-octyl phthalate, triphenyl phosphate, octyl epoxy soybean oleate, dioctyl sebacate, diisodecyl phthalate, and diphenyl-octyl phosphate.
As a preferred technical scheme, the plasticizer is dihexyl phthalate.
As a preferable technical scheme, the flame retardant is a mixture of an organic flame retardant and an inorganic flame retardant, and the weight ratio of the organic flame retardant to the inorganic flame retardant is (2-5): 1.
as a preferable technical scheme, the organic flame retardant is an organic bromine flame retardant and/or an organic phosphorus flame retardant.
As a preferable technical scheme, the organic bromine flame retardant is at least one selected from decabromodiphenylethane, (4-bromophenyl) diphenyl phosphorus oxide and p-bromoethylbenzene.
As a preferable technical solution, the inorganic flame retardant is at least one selected from antimony trioxide, magnesium hydroxide, aluminum hydroxide and zinc borate.
The brominated flame retardant is a novel pollution-free flame retardant, does not generate toxic substances during combustion, has better thermal stability, better flame retardant effect and better dispersibility and miscibility in resin, and is beneficial to the molding processing of the resin. The inorganic flame retardant has good thermal stability and good smoke suppression effect, and can slow down the thermal decomposition temperature of the resin under the condition of a certain using amount, but the inventor finds that the fluidity of the resin is deteriorated and the molding processability of the resin is influenced when the adding amount is large, so the adding amount of the inorganic flame retardant is controlled within a certain range.
In a preferred embodiment, the ultraviolet absorber is at least one selected from the group consisting of salicylates, benzophenones, benzotriazoles, acrylonitriles, and triazines.
As a preferable technical scheme, the ultraviolet absorbent is a benzotriazole.
The molecules of the benzotriazole ultraviolet absorbent contain ortho-hydroxyphenyl substituent groups, and a chelate ring is formed by ortho-hydroxyl and nitrogen atoms or oxygen atoms in the compound, after the compound absorbs ultraviolet rays, hydrogen bonds are broken to generate molecular isomerism, the intramolecular structure generates thermal vibration, the hydrogen bonds are broken, the chelate ring is opened, the intramolecular structure is changed, and thus harmful ultraviolet light is changed into harmless heat energy to be released, so that the high-molecular polymer material is protected. However, the radicals and peroxides generated by the ultraviolet irradiation are not eliminated by the ultraviolet absorber and remain in the polymer material, which is harmful to the properties of the polymer. By adding a certain amount of hindered amine light stabilizer, the hindered amine light stabilizer is oxidized to produce corresponding nitroxide free radicals, and the nitroxide free radicals can effectively capture free radicals generated by photolysis and peroxide generated by decomposition so as to prevent oxidative degradation of high molecular polymers and improve yellowing resistance and aging resistance of the whole decorative material.
The second aspect of the present invention provides a method for preparing the decorative material, which at least comprises the following steps:
(1) mixing epoxy resin, reinforcing filler, plasticizer, flame retardant, ultraviolet absorbent, coupling agent, hindered amine light stabilizer and foaming agent to prepare a molding material;
(2) and (3) putting the mould material into a mould, carrying out hot press molding, and cooling to obtain the product.
