Embodiment 1
[0020] Embodiment 1: A refrigerator drawer decorative strip and its processing technology, comprising the following steps: Step 1, mixing ingredients: raw materials by weight 45 parts of calcium powder, 70 parts of PVC resin of SG-8, 5 parts of CPE, 3.5 parts of stabilizer 0.5 part of stearic acid, 0.5 part of PE wax, 1 part of dioctyl ester, 1 part of ACR and 1 part of hot silver transfer film. Weigh calcium powder, PVC resin, CPE, stabilizer, stearic acid, PE Wax, dioctyl ester and ACR are mixed in a high-speed mixer, and the mixing temperature is raised to 120°C for 20-30 minutes to obtain a hot mixture;
[0021] Step 2. Cool down: cool down the hot mixture to 45~55℃, and the cooling time is 10~15min;
[0022] Step 3, primary plasticization: send the material obtained in step 2 into the plasticizing machine to heat and plasticize. The plasticizing machine is equipped with 5 temperature zones, and the temperature of the 5 temperature zones is set at 183°C, 182°C, 180°C, 170...
Embodiment 2
[0026] The difference between embodiment 2 and embodiment 1 only lies in:
[0027] Mixing ingredients: raw materials by weight 50 parts of calcium powder, 75 parts of PVC resin, 5 parts of CPE, 3.5 parts of stabilizer, 0.6 parts of stearic acid, 0.6 parts of PE wax, 1 part of dioctyl ester, 1 part of ACR and hot silver transfer printing Weigh 1.2 parts of the film, put calcium powder, PVC resin, CPE, stabilizer, stearic acid, PE wax, dioctyl ester and ACR into a high-speed mixer for mixing, the mixing temperature rises to 125°C, and the time is 20~30min, a hot mixture is obtained.
Embodiment 3
[0028] The difference between embodiment 3 and embodiment 1 only lies in:
[0029] Mixing ingredients: raw materials by weight 50 parts of calcium powder, 80 parts of PVC resin, 8 parts of CPE, 5 parts of stabilizer, 1 part of stearic acid, 0.8 parts of PE wax, 1.5 parts of dioctyl ester, 1.5 parts of ACR. Weigh 1.5 parts of the transfer film, put calcium powder, PVC resin, CPE, stabilizer, stearic acid, PE wax, dioctyl ester and ACR into a high-speed mixer for mixing, and the mixing temperature is raised to 130°C. The time is 20~30min, and a hot mixture is obtained.

Abstract
The invention discloses a refrigerator drawer decorating strip in the field of processing and manufacturing of refrigerators and a processing technology of the refrigerator drawer decorating strip. The refrigerator drawer decorating strip comprises the following raw materials in parts by weight: 45-50 parts of calcium powder, 70-80 parts of PVC resin, 5-8 parts of CPE, 3.5-5 parts of a stabilizer, 0.5-1 part of stearic acid, 0.5-0.8 part of PE wax, 1-1.5 parts of dioctyl phthalate, 1-1.5 parts of ACR and 1-1.5 parts of a silver plated transfer printing film. The process comprises the following steps: mixing: after mixing ingredients, heating to obtain a hot mixture; cooling: cooling the hot mixture until the temperature reaches 45-55 DEG C; primary plasticizing: feeding a material obtained from the step two into a plasticator for heating and plasticizing, and extruding particles out; secondary plasticizing: conveying the particles obtained from the step three to a hard shaping machine, and extruding and heating to obtain a plasticized material; and heat transfer printing: feeding the plasticized material to heat transfer printing equipment and carrying out surface printing to obtain the silver plated refrigerator drawer decorating strip. By the two-time plasticizing technology and the heat transfer printing technology, surface gloss of the plasticized material is ensured to guarantee the effect of heat transfer printing, and the decorating strip is metallic, and is attractive and elegant in appearance.
Description
technical field [0001] The invention relates to the field of processing and manufacturing of a refrigerator, in particular to a decorative strip for a refrigerator drawer and a processing technology thereof. Background technique [0002] Refrigerators, freezers and other home appliances widely use drawer doors as storage mechanisms, which have the characteristics of large storage capacity, strong durability, and flexible retrieval. [0003] Existing refrigerator drawers are mainly made up of guide rails, slide rails, rollers, drawers and decorative strips, and the decorative strips and drawers are made of different materials respectively. [0004] At present, the upper and lower decorative strips of the front door of the refrigerator are made of plastic parts. In order to achieve both beautiful and durable effects, most manufacturers design to spray metal texture paint on the plastic parts. However, this will not only easily pollute the environment, but also spray parts Low...
