| titleOfInvention | Photoluminescent walkway block formed by double injection method using waste plastic and its manufacturing method |
| abstract | The present invention relates to a method of manufacturing a photoluminescent walkway block formed by a double injection method using waste plastics, the composition of which is an impurity removal process for removing impurities remaining in the waste plastic collected for recycling; and, impurities are removed Permeable resin composed of ABS resin (Acrylonitrile Butadiene Styrene resin), which has good light transmittance and excellent gloss, and PMMA resin (Polymethly Methacrylate resin) among the used waste plastics, and PP resin (Polypropylene) having low light transmittance and low gloss A sorting step of sorting with a non-permeable resin composed of a resin); A pulverizing step of finely pulverizing the permeable resin and the non-permeable resin, respectively, selected in the sorting process; and, after blending the pulverized non-permeable resin in a weight range of 10 to 15 wt% to a flame retardant 85 to 90 wt%, Primary mixture production process by mixing evenly so that there is no solid material using; and the phosphorescent pigment 4 to 8wt%, flame retardant 10 to 15wt%, impact modifier 1 to 3wt%, UV stabilizer to 73 to 84wt% of the ground permeable resin (UV Stabilizers) After mixing in a weight range of 1wt%, using a stirrer to mix the secondary mixture evenly so that there is no solid; And, the primary mixture produced in the primary mixture production process into a double injection mold After the primary mixture is formed into a lower plate, the secondary mixture is introduced into a double injection mold to form a secondary mixture into an upper plate, so as to contact the upper surface of the lower plate. A double injection process of molding the photoluminescent press block combined with the lower plate and the upper plate by injection; and an inspection and packaging process of inspecting the photoluminescent press block manufactured by the double injection process and packaging the finished product; As characterized by then n n Various types of waste plastics collected by recycling are sorted to separate them according to their characteristics or functions, and the selected waste plastics are divided into lower and upper plates to be firmly combined with each other to complete sidewalk blocks to maximize the efficiency of waste plastic recycling. It can work.n n n In addition, by molding the lower plate and the upper plate having different materials by the double injection molding method, the press block combined with the lower plate and the upper plate is manufactured through one injection process, thereby improving the productivity of the press block and reducing the cost. It has an effect.n n n In addition, by adding a photoluminescent pigment to the mixture constituting the top plate and injecting to form a civil mark, pattern mark, braille mark, and induction mark on the upper surface of the top plate, the functional expression of the use is clear without distinction between day and night It has the effect of making it work.n n n n Top plate, bottom plate, sidewalk block, double injection method, photoluminescent pigment, waste plastic |
