Description

Environment-friendly root-puncture-resistant PVC waterproof coiled material and preparation method thereof
Technical Field
The application relates to the technical field of waterproof coiled materials, in particular to an environment-friendly root-puncture-resistant PVC waterproof coiled material and a preparation method thereof.
Background
The PVC waterproof coiled material is a polymer waterproof coiled material which is formed by taking PVC resin as a base material, adding a certain amount of plasticizer, anti-aging agent, heat stabilizer, ultraviolet absorber, lubricant, filler and other processing aids, and performing one-time extrusion molding. At present, phthalate plasticizers are main plasticizers of polyvinyl chloride waterproof coiled materials, and the plasticizers mainly comprise dioctyl phthalate (DOP), dibutyl phthalate (DBP), diheptyl phthalate (DHP), diisodecyl phthalate (DIDP), diisooctyl phthalate (DIOP) and the like. Meanwhile, a lead salt type heat stabilizer is usually selected in a formula system of the PVC coiled material. It is now widely recognized that plasticizers in PVC coils migrate and lead salts slowly migrate to the surface of the coils with the plasticizers, they penetrate into the ground with rain, enter the water environment and soil, and eventually enter the body with drinking water and food. Along with the development of science, phthalate plasticizers are found to be difficult to degrade due to the fact that the phthalate plasticizers contain aromatic rings, chronic toxicity has quite large harm to human beings, liver tissue canceration can be caused, endocrine disruption is caused, and the use of phthalate plasticizers in European countries is limited; meanwhile, when the lead salt in the human body reaches a certain concentration, the liver is damaged, and the hematopoietic system and the nervous system of the bone marrow are damaged.
Meanwhile, plasticizer migration can also seriously affect the quality of a welded joint of a coiled material, so that the waterproof sealing performance is poor, and even water seepage of the joint is caused. In addition, PVC coils have been added with larger amounts of inorganic fillers due to dimensional stability requirements, resulting in greater water absorption (> 2.0%) of the coils. In the underground environment, mould, bacteria and the like in the soil can also enter the coiled material along with moisture, so that the mould corrosion resistance and the plant root puncture resistance of the coiled material are seriously affected.
The prior art has the following defects: (1) The phthalate plasticizer and the lead salt stabilizer are used, so that the health of human bodies can be endangered, and the environment is not protected; (2) Plasticizer migration seriously affects the overall waterproof effect of the coiled material; (3) The coiled material has high water absorption and poor mildew corrosion resistance and plant root puncture resistance.

Furthermore, when the environment-friendly root penetration-resistant PVC waterproof coiled material is in waterproof construction, hot air welding is carried out on long and short edges by adopting a seam welder, the welding width is 80-85 mm, the part of the elastomer film layer which is more on one side of the long edge is directly welded on the elastomer film layer on the upper surface of the other coiled material, and a sheet which is the same as the elastomer film layer and has the thickness of 1.2-2.0 mm and the length of 150-200 mm is adopted as a cover strip, and the hot air is welded at a weld joint of a short edge for reinforcement treatment.
The environment-friendly root penetration-resistant PVC waterproof coiled material disclosed by the application is subjected to a great deal of optimization on the use of raw materials, and particularly comprises the following three parts:
(1) the root-blocking plasticizer is used as the plasticizer of the PVC coiled material, has plasticizing effect on PVC resin powder and passivating effect on plant root systems, and is an environment-friendly plasticizer. The plasticizer has small molecular weight distribution coefficient and low molecular weight components, is difficult to migrate and precipitate in PVC coiled materials, is insoluble in water, resists water extraction, and cannot enter underground water systems. Meanwhile, the calcium-zinc composite heat stabilizer is selected for the PVC coiled material, and the stabilizer does not contain heavy metals such as lead salt and the like, so that the environment is not polluted, and the harm to human bodies is not caused in the production link of the PVC coiled material.
(2) Preferably, 2000 mesh light calcium carbonate or/and 2500 mesh heavy calcium carbonate subjected to oleophilic and hydrophobic modification is/are used for the PVC coiled material, so that the water absorption rate of the coiled material is smaller while the size change rate and hardness of the coiled material are improved. The surface energy of the powder after the hydrophobic modification is reduced, the compatibility with a PVC resin system is increased, the interface between inorganic and organic is eliminated, and the water absorption rate of the coiled material is reduced.
(3) The PVC coiled material provided by the application adopts the elastomer film layer, so that the excellent welding performance of the ethylene-propylene elastomer resin material can be utilized, the seam firmness and durability are higher, and the waterproof reliability is improved. The ethylene-propylene resin has compact molecular structure, low thermal dimensional change rate, high puncture resistance, strong physical root resistance, and simultaneously imparts chemical root resistance, so that the root resistance is particularly remarkable, meanwhile, the ethylene-propylene resin does not absorb water, and the film layer contains little filler, so that the film layer has extremely low water absorption rate, so that moisture is not easy to permeate and migrate to the PVC sheet layer, the water absorption rate of the PVC coiled material is reduced, and the root puncture resistance of the coiled material is remarkably improved.
Compared with the prior art, the application has the beneficial effects that,
(1) the PVC waterproof coiled material does not contain phthalate plasticizers and lead salts, so that the PVC waterproof coiled material is higher in environmental protection.
(2) The PVC waterproof coiled material has high seam peeling strength, and the welding seam is firm and durable.
(3) The PVC waterproof coiled material disclosed by the application is extremely low in water absorption rate, has dual functions of physical root resistance and chemical root resistance, and has excellent mould corrosion resistance and root puncture resistance.
(4) The components such as the root-blocking plasticizer, the mildew-resistant auxiliary agent, the ethylene-propylene elastomer and the like adopted by the PVC waterproof coiled material are mutually matched tightly to cooperatively realize the improvement of the root penetration resistance of the coiled material. The root-blocking plasticizer can effectively prevent plant root systems from growing into coiled materials; the mildew-resistant auxiliary agent MICROPEL 5 PVC is a spectrum antibacterial mildew-resistant agent, and can effectively protect PVC coiled materials from being corroded by harmful bacteria, fungi, algae and other organic microorganisms for a long time, so that the coiled materials can well maintain the original physical properties; the ethylene-propylene elastomer has higher crystallinity, compact molecular structure, chemical corrosion resistance and strong puncture resistance against plant root systems.
(5) The PVC waterproof coiled material creatively combines the film made of the root-resistant modified ethylene-propylene elastomer resin with the PVC sheet layer, and the preparation mode of high-temperature fusion lamination compounding through the calendaring rollers can ensure high compounding strength, and all the layers are firmly combined to form a unified whole; in addition, the parts of the upper and lower elastomer film layers of the PVC sheet layers which are arranged on the long sides of the coiled material can be compounded together to realize edge sealing protection of the PVC sheet layers, so that the 'full-package' protection of the ethylene-propylene elastomer film layer is added besides the protection effect of components such as root-blocking plasticizer, mold-resistant auxiliary agent, ethylene-propylene elastomer and the like, and the PVC coiled material provided by the application is endowed with excellent root penetration resistance.

Table 1 basic properties of waterproof roll
Table 2 waterproof roll application Properties
As can be seen from Table 1, compared with the prior art, the environment-friendly root penetration-resistant PVC waterproof coiled material prepared by the application has larger joint peeling strength and improved tensile strength. The most obvious characteristic is that the water absorption rate of the environment-friendly root-resistant PVC waterproof coiled material prepared by the application is smaller than that of the prior art. The elastomer film layer adopted by the application improves the tensile strength of the PVC waterproof coiled material, and as can be seen by comparing the example 1 with the comparative example 4 and the comparative example 5, the elastomer film layer and the modified filler are both helpful for reducing the water absorption rate of the coiled material, and the components of the application have synergistic effect.
The environment-friendly root-puncture-resistant PVC waterproof coiled material prepared by the application can be obtained from the detection of harmful substances of coiled materials, and the phthalate and lead can not flow out because the phthalate and lead are not added, so that the environment and human body can not be damaged.
As can be seen from Table 2, compared with the prior art, the environment-friendly root penetration-resistant PVC waterproof coiled material prepared by the application has better mold corrosion resistance, and the environment-friendly root penetration-resistant PVC waterproof coiled material prepared by the application has better compactness, low water absorption rate and difficult mold growth.
