Embodiment 1

[0024] Based on 100 parts by mass of PVC SG3 resin, 50 parts of dioctyl phthalate, 1 part of the compound of calcium zinc stabilizer and organic tin stabilizer, 0.02 part of fluorescent whitening agent, 5 parts of antioxidant 1010, spherical poly 1 part of silsesquioxane light diffusing agent and 1 part of transparent toner are dispersed and mixed uniformly in a high-speed stirring mixer, and a light-diffusing soft color PVC composition is produced by screw extrusion. When the composition is injection-molded into a film or strip with a thickness of 2 mm, it is soft, bright in color, can be bent arbitrarily, has a haze of 90 percent and a light transmittance of 83 percent.

Embodiment 2

[0026] 100 parts by mass of PVC SG3 resin, 100 parts of dioctyl phthalate, 4 parts of the compound of calcium zinc stabilizer and organic tin stabilizer, 0.2 part of optical brightener as light stabilizer, 0.5 part of antioxidant 1010 4 parts of cross-linked polymethyl methacrylate microsphere light diffusing agent, 5 parts of transparent toner, dispersed and mixed evenly in a high-speed stirring mixer, and extruded by a screw to produce a light-diffusing soft color PVC combination. When the composition is injection-molded into a film or rubber strip with a thickness of 2 mm, it is soft, bright in color, can be bent arbitrarily, has a haze of 93 percent and a light transmittance of 76 percent.

Embodiment 3

[0028] 100 parts by mass of PVC SG3 resin, 70 parts of dioctyl phthalate, 3 parts of calcium zinc stabilizer and organic tin stabilizer compound, 0.1 part of fluorescent whitening agent, 2 parts of antioxidant 1010, cross-linked 2 parts of polystyrene microsphere light diffusing agent and 5 parts of transparent toner are dispersed and mixed evenly in a high-speed stirring mixer, and extruded by a screw to produce a light-diffusion type soft color PVC composition. When the composition is injection-molded into a film or strip with a thickness of 2 mm, it is soft, bright in color, can be bent arbitrarily, has a haze of 92 percent and a light transmittance of 71 percent.

Abstract

The invention relates to the technical field of high-polymer materials, and discloses a photodiffusion-type flexible colored PVC (polyvinyl chloride) composition and application thereof in photodiffusion-type flexible colored LED (light-emitting diode) decorative lamp bars. The composition comprises the following components in parts by weight: 100 parts of PVC resin, 50-100 parts of plasticizer, 1-4 parts of heat stabilizer, 0.02-0.2 part of light stabilizer, 0.5-5 parts of antioxidant, 1-4 parts of photodiffusant agent and 1-8 parts of transparent toner. The composition is prepared by the following steps: uniformly dispersing and mixing the components in a high-speed mixing machine, and carrying out screw extrusion granulation while controlling the screw temperature at 120-180 DEG C. The thickness of the rubber strip extruded by the extruder is 2mm, the haze is greater than or equal to 90%, and the light transmittance is greater than or equal to 70%. By using the high-yield low-price PVC resin as the main material and adding the cheap plasticizer and the composition composed of the heat stabilizer, light stabilizer, antioxidant, spherical photodiffusant, transparent toner and other aids, the prepared photodiffusion-type flexible PVC rubber strip has the advantages of low price and bright color, and overcomes the defects in PC (polycarbonate), PMMA (polymethyl methacrylate) and PS (polystyrene).

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a soft colored PVC composition and application thereof, in particular to a light diffusion type soft colored PVC composition and its application in LED strip-shaped decorative lamps . Background technique [0002] Among LED lighting materials, light diffusing polycarbonate (PC), polymethyl methacrylate (PMMA), and polystyrene (PS) are the most widely used materials, but these materials are usually used For the manufacture of hard devices, and for some requirements to use soft materials, especially when manufacturing soft strip LED decorative lights, PC, PMMA, PS materials are difficult to meet the requirements. [0003] PVC is one of the earliest industrialized plastic products in the world. It is the second largest general-purpose plastic. Its usage is second only to polyethylene (PE). Its strength and modulus are the first among general-purpose plastics. It has excel...
