the preparation method of the environment-friendly liquid laundry detergent plastic bottle comprises the following steps:
step one: pouring PBAT, polylactic acid, calcium carbonate powder and white fibrilia into a mixer for mixing, and uniformly mixing at the rotating speed of 1100-1600 rpm to obtain a mixture A;
step two: pouring the mixture A obtained in the step one into heating stirring equipment for stirring, stirring the mixture A at 160 ℃, adding a plasticizer, an oxidant, a stabilizer and a lubricant into the heating stirring equipment, and stirring for 55 minutes to obtain a mixture B;
step three: adding a photosensitizer and a colorant into the mixture B obtained in the step two, and continuously mixing to obtain a mixture C;
step four: adding the mixture C obtained in the step three into a blow molding machine, extruding the mixture into bottle blanks by the blow molding machine at the temperature of 170 ℃, then blowing up, and then cooling and molding in cold water to obtain a primary liquid laundry detergent plastic bottle;
step five: cutting and polishing the convex parts or burrs of the liquid laundry detergent plastic bottle prepared in the step four;
step six: and (3) feeding the cut and polished laundry detergent plastic bottles into inspection equipment, and inspecting whether the laundry detergent plastic bottles leak air or not.
Specifically, the plasticizer may be one or more of phthalate esters, aliphatic dibasic acid esters, phosphate esters and chlorinated paraffin.
Specifically, the antioxidant is peroxide decomposer, which can be one of Liu Chun acute thioether, thiopropionate, organic phosphorous acid compound and dithionate.
Specifically, the stabilizer can be one of a calcium-zinc stabilizer or a low-toxicity barium-cadmium-zinc stabilizer.
In particular, the lubricant may be monoglyceride of stearic acid.
Specifically, the photosensitizer may be one of iron diethyldithiocarbamate and iron dibutyldithiocarbamate.
Specifically, the length of the white fibrilia ranges from 20mm.
Specifically, the rotational speeds involved in step 1 are in order: 1100 rpm, 1500 rpm and 1600 rpm.
Specifically, the device for checking whether the air leaks in the step six may be a bottle air leak quick detecting machine.
The laundry detergent plastic bottles prepared in examples 1-3 were tested for tensile strength, elongation at break and impact strength, 30 laundry detergent plastic bottles were randomly drawn, 10 were grouped, and the tensile strength, elongation at break and impact strength were tested, respectively, and averaged.
Table 3: tensile strength, elongation at break and impact strength of laundry detergent plastic bottles
| Tensile Strength/Mpa | Elongation at break/% | Impact strength/Mpa | |
| Plastic bottle for liquid laundry detergent | 48.65 | 52 | 18.95 |
