Embodiment

[0031] A special material for septic tanks, its components and parts by weight are as described in Table 1, and it is prepared by the following method:

[0032] S1. Mix HDPE, calcium carbonate, PP, naphthenic oil, zinc stearate and SEBS in the formula, soften and melt at 80-150°C;

[0033] S2, pulverizing the anti-biological agent and spraying it with LLDPE melt, cooling to room temperature to obtain anti-biological microcapsules;

[0034] S3. Add the anti-biological microcapsules obtained in S2 to the melt of S1, and inject to obtain the special material for septic tanks described in this application.

Abstract

The invention discloses a septic tank special material with good processing fluidity. The septic tank special material is prepared from the following components in parts by weight: 100 parts of HDPE (high-density polyethylene); 5 to 20 parts of calcium carbonate; 1 to 10 parts of PP (propene polymer); 1 to 5 parts of naphthenic oil; 0.5 to 2 parts of zinc stearate. The invention also discloses a preparation method of the septic tank special material. The preparation method comprises the following steps: S1, mixing the HDPT, the calcium carbonate, the PP, the naphthenic oil, the zinc stearate and the SEBS, softening and fusing; S2, smashing an anti-bio agent and spraying on LLDPE (linear low density polyethylene) flux, and cooling to room temperature, so as to obtain an anti-bio microcapsule; S3, adding the anti-bio capsule obtained in S2 into the fusant of S1, and performing injection molding.

Description

technical field [0001] The invention relates to the field of septic tank sewage treatment, more specifically, it relates to a special material for septic tanks and a preparation method thereof. Background technique [0002] Septic tank is a treatment facility that uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage. It is a primary transitional domestic sewage treatment structure, so it plays a role in purifying sewage and preventing pipeline blockage. positive effect. The traditional septic tank is made of brick or concrete, but this traditional septic tank will leak after a period of use, and the sewage will enter the underground environment and cause secondary pollution to groundwater. In addition, these The traditional septic tank is relatively bulky, and its construction and maintenance are relatively inconvenient. Therefore, using new materials to build septic tanks has become one of the key research an...
