Problems solved by technology

[0006] 1. Washing with a single high-concentration lye, the PET material will be cracked under the action of strong alkali for a long time, so that the characteristics will be reduced. Because the types of residual glue are complex, heavy alkali cannot effectively remove all glue , does not have any cleaning effect on the pollutants in the capillary pores
[0007] 2. Washing with commercially available industrial cleaners may have a better effect than the above item, but the general commercially available ingredients do not have targeted formulas, and the washing effect cannot achieve the target, and they often contain nonylphenol and sodium tripolyphosphate. Environmentally Sensitive or Unfriendly Ingredients
[0008] 3. Use high-intensity mechanical force to rub the surface of PET, and use the method of grinding away the surface of the material to achieve the purpose of removing pollutants. The removal of residual glue can achieve a certain degree of effect, but PET bottle flakes are not regular flat surfaces. Therefore, there are still dead corners that cannot be removed, and it has no effect on cleaning por

Embodiment 1

[0033] A kind of PET bottle flake reuse processing soaking agent, is formed by mixing the raw materials of following components and parts by weight:

[0034]

[0035] The detergent can be prepared as a powder by general drying or vacuum drying, and is suitable for soaking recycled PET bottle flakes.

[0036] When the leaching agent prepared in this example and the commercially available tablet washing agent A are used for rinsing of general PET bottle flakes (there is no similar product sold in the market, compared with PET tablet washing agent), the rinsing effects are compared as shown in Table 1 :

[0037] Table 1

[0038]

[0039] Analysis of Table 1 shows that for general PET bottle flakes, the commercially available tablet washing agent A has no rinsing effect and cannot remove the infiltration residue in the capillary pores of PET, but the rinsing agent of this embodiment can achieve the effect.

Embodiment 2

[0041] A kind of PET bottle flake reuse processing soaking agent, is formed by mixing the raw materials of following components and parts by weight:

[0042]

[0043] The detergent can be prepared as a powder by general drying or vacuum drying, and is suitable for soaking recycled PET bottle flakes.

[0044] When the leaching agent prepared in this example and the commercially available tablet washing agent B are used for rinsing PET oil bottle tablets (there is no similar product sold in the market, compared with the PET washing tablet), the rinsing effect comparison is shown in Table 2 :

[0045] Table 2

[0046]

[0047] Dilution ratio

[0048] Analysis of Table 2 shows that for PET oil bottle tablets, the commercially available washing tablet B has no soaking effect and cannot remove the infiltration residue in the capillary pores of PET, but the soaking agent of this embodiment can achieve the effect.

Embodiment 3

[0050] A kind of PET bottle flake reuse processing soaking agent, is formed by mixing the raw materials of following components and parts by weight:

[0051]

[0052] The detergent can be prepared as a powder by general drying or vacuum drying, and is suitable for soaking recycled PET bottle flakes.

[0053] When the leaching agent prepared in this example and the commercially available tablet washing agent C are used for rinsing of general PET bottle flakes (there is no similar product sold in the market, compared with the PET washing tablet), the rinsing effects are compared as shown in Table 3 :

[0054] table 3

[0055]

[0056] Solubility

[0057] Analysis of Table 3 shows that for general PET bottle flakes, the commercially available tablet washing agent C has no rinsing effect and cannot remove the infiltration residue in the capillary pores of PET, but the rinsing agent of this example can achieve the effect.

Abstract

The invention relates to a reusing treatment immersion cleaning agent for a PET bottle flake. The reusing treatment immersion cleaning agent is prepared from the following raw materials in parts by weight: 10-25 parts of a compound surfactant, 1-5 parts of a chelating agent, 5-15 parts of a buffering agent, 1-5 parts of an expanding agent, 10-25 parts of a saponifier and 40-80 parts of a filler. Compared with the prior art, by adopting the surfactant compounded by surfactants with the emulsion dispersion property and the seepage property, the reusing treatment immersion cleaning agent has the strengthened seepage property and is capable of easily seeping into capillary pores of the bottle flake to remove pollutants. As for removing pollutants in the capillary pores with hard surfaces, the mechanical force is useless, and sufficient seepage time is needed, so that the formula needs to be operated in a static impregnation mode. When being used, the impregnation time of the PET bottle flake is generally 8-15 minutes, and the impregnation time of an oil bottle flake which is severely polluted is 20-35 minutes.

Description

technical field [0001] The invention relates to a leaching agent, in particular to a leaching agent for recycling PET bottle flakes. Background technique [0002] The cleaning of recycled PET bottles or other plastics belongs to the washing characteristics of "hard surfaces". The combination of pollutants and hard surfaces has several types such as polar adhesion, adhesive adhesion, capillary penetration and coating adhesion. Due to the characteristics of the product and material, the pollutants that are difficult to deal with in recycled PET bottles mostly occur in two types: adhesion and capillary penetration. [0003] Adhesion Adhesion is mostly manifested in the residue of the glue used for sticky labels on the surface of the PET material. In practical applications, there are more than a dozen types of glue used for labels, so the removal efficiency of various glue types varies greatly. Residual glue remains in the processing of PET recycled raw materials and subsequent...
