Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions provided by the embodiments of the present invention are described in detail below.
The embodiment of the invention discloses a material for a shell and/or a mask of a lamp, which comprises the following raw materials in parts by weight:
the homopolypropylene (homopolyPP) and the random copolymerization polypropylene (random copolymerization PP) are main raw materials of the material, and the compound melt index range of the homopolypropylene and the random copolymerization polypropylene in the embodiment is 10-20g/10 min. The melt index was measured under the conditions specified in the national standard, where the temperature was 230 ℃ and the mass was 2.16 kg.
The photodiffusion modifier is a main reagent for adjusting the optical transmittance in the material, and refers to special organic siloxane resin spherical micro powder (preferably Dow Corning EP2720) or polymethyl methacrylate photodiffusion agent (preferably Japanese Brillouin MP-90), and the functional group has good dispersibility in a plastic base material.
In this example, the blue light modifier (i.e., blue light absorber) refers to nano zinc oxide or nano cerium oxide, and has an average particle diameter of 10 to 30nm, preferably DK-ZnO-15 or DK-CeO of Beijing Dekkera2-20；
In this example, the antioxidant functions primarily to prevent oxidation of the material during processing. In the related art, there are various kinds of antioxidants. Experiments show that the hindered phenol antioxidants (such as the antioxidant 1076) and the phosphite antioxidants (such as the antioxidant 168) can improve the oxidation resistance of the material in the processing process.
The long-term anti-aging auxiliary agent has the function of improving the long-term anti-aging performance of the material during use. In this embodiment, a hindered amine-based anti-aging aid, a hindered phenol-based anti-aging aid, a phosphite complex-based anti-aging aid, or the like may be used. The phosphite compound anti-aging additive such as UV-944 comprises 1,3, 5-trimethyl-2, 4, 6- (3, 5-di-tert-butyl-4-hydroxybenzyl) benzene/tetra (2, 4-di-tert-butylphenyl) 44 biphenyl diphosphite as an internal component, has a good light stabilizing effect, and can enable the material to have good photo-oxidative aging performance under long-term photo-thermal conditions.
In the embodiment, the glow wire improvement aid has the effect of improving the performance of the glow wire of the material, so that the material has stronger fire resistance and high temperature resistance. The experiment shows that the pentabromobenzyl polyacrylate is more suitable for the material.
The transparent modifier (i.e. nucleating agent) is a new functional assistant in incomplete crystallization plastics such as polyethylene, polypropylene and the like, and can accelerate crystallization rate, increase crystallization density and promote grain size refinement by changing crystallization behavior of resin, so as to achieve physical and mechanical properties such as shortening molding period, improving product transparency, surface gloss, tensile strength, rigidity, heat distortion temperature, impact resistance, creep resistance and the like. Experiments show that the material has more excellent material performance by adopting the sorbitol nucleating agent. The sorbitol-based nucleating agent may be 1,3:2, 4-bis 3, 4-dimethylbenzylidene sorbitol acetal.
The properties of the materials provided herein are further illustrated by experimentation.
Experimental example:
the raw materials of the experimental examples and comparative examples are shown in table 1:
table 1 raw material table
(Note: in comparative example 2, PMMA is Mitsubishi PMMA-VH001)
Respectively putting the components into a low-speed mixer, stirring for 5 minutes to uniformly mix the components, discharging, and then extruding and granulating by using a double-screw extruder; wherein the processing temperature of the screw extruder is 180-200 ℃, the specific temperature setting is shown in Table 2, and the screw revolution is 30 HZ.
TABLE 2 screw temperature set point
The pellets formed in the experimental examples and the comparative examples were subjected to various property tests according to national standards, and the test results are shown in Table 3.
Table 3 results of performance testing
As can be seen from Table 3, the density, glow wire, and injection cycle parameters of the materials of examples 1-4 substantially reached or even exceeded the performance of the current PMMA material (comparative example 2). Meanwhile, the density of the experimental examples 1-4 is obviously lower than that of PMMA material, and the weight is lighter under the same volume; and as the main material is polypropylene, the material has obvious price advantage compared with PMMA material; meanwhile, the photo-oxidative aging performance of the experimental examples 1-3 is obviously better than that of a PMMA material, so that the material has longer service life.
In addition, as can be seen from table 3, although the main raw materials and the mixture ratios adopted in comparative example 1 and experimental examples 1-4 are substantially the same, due to the differences of the types of the additives and the performance of the parameters, the comparative example 1 has obvious defects in the performance aspects of glow wire ignition temperature, injection molding cycle and the like, and cannot meet the performance requirements of the shell and/or the face mask of the lamp.
In summary, the material for the housing and/or the face mask of the lamp provided by the embodiment of the invention has a transmittance similar to that of the conventional PMMA material, a higher glow wire ignition temperature, a lower density, a shorter molding cycle, and a more excellent photo-oxidation aging property.
The material that is used for casing and/or face guard of lamps and lanterns that this embodiment provided can be applied to various lamps and lanterns, include and be not limited to down lamp, ceiling lamp, kitchen and bathroom lamp, ornament lamp, desk lamp etc. can reduce lamps and lanterns cost when promoting lamps and lanterns performance by a wide margin. It should be noted that, although the material of the shell and/or the mask of the lamp provided in this embodiment is generally applied to the shell and/or the mask of the molded lamp, it is not excluded to apply the material to the molding of lamp components whose operating conditions require to be similar to those of the shell or the mask, and even to apply the material to components whose operating conditions require to be similar to those of other electrical products.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
