Embodiment 1

[0024] Step 1: Use 5 parts by weight of copper chloride and 5 parts by weight of ethylenediaminetetraacetic acid to prepare a solution, add 4 parts by weight of sodium hexadecylsulfonate into the solution and stir evenly, and finally add 5 to 10 parts by weight of Parts of sodium citrate, stir to mix well. The mixed solution was irradiated with a pulsed laser with a power of 10 W, a frequency of 20 Hz, and a processing time of 10 minutes. Copper nanowires were obtained by centrifugation under vacuum.

[0025] Step 2: Disperse 10 parts by weight of copper nanowires into a 1:1 mixture of 100 parts by weight of distilled water and ethanol, add 15 parts by weight of polyethylene glycol trimethoxysilyl propyl ether, control the reaction time for 8 hours, and the temperature at 40°C to obtain the modified copper nanowire fluid.

[0026] Step 3: The master batch of the coil cladding material is mainly prepared from the following raw materials according to the weight percentage of e...

Abstract

The invention discloses a preparation method of a copper nanowire toughened root-blocking waterproof coiled material cladding material, which solves the problems of poor adhesion and coordination between the existing clad material and the coiled material, and the problem that the root-blocking performance needs to be further improved. The technical solution includes the preparation of modified copper nanowire fluid: disperse 5-10 parts by weight of copper nanowires into 100 parts by weight of ethanol with a concentration of 50%, add 8-15 parts by weight of silane coupling agent and mix to obtain modified copper Nanowire fluid; preparation of coil coating material: the coil coating material is prepared by mixing the following raw materials through film processing, and the raw materials are: high-density polyethylene 75-80%, additives 1-5%, modified Copper nano wire fluid 10-15%, anti-aging agent 1-5%, stabilizer 1-5%. The invention has simple operation and high controllability, and the prepared copper nanowire has good compatibility with the coiled material, which can not only enhance the root-resistance characteristics of the material, but also ensure the adhesion and coordination between the cladding material and the coiled material, and has the advantages of Toughening enhancement.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a method for preparing a waterproof roll material cladding material. Background technique [0002] At present, as the requirements for building life become more and more stringent, people's demand for building waterproofing is gradually increasing, and the demand for waterproofing in areas such as building exterior walls and roofs is more stringent. Commonly used waterproof membrane products are waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass to form membranes. It is mainly divided into asphalt waterproofing membrane, polymer modified asphalt waterproofing membrane and synthetic polymer waterproofing membrane. Waterproof membranes are required to have good water resistance, stability to temperature changes, no flow, no foaming, no confusion at high temperatures; no brittle cracks at low temperatures, certain mechanical ...
