Technical method of novel root resisting copper mold based electrolytic copper foil

Abstract

The invention discloses a technical method of a novel root resisting copper mold based electrolytic copper foil. The method comprises the following steps: producing a single-surface photoelectrolyticcopper foil through a special anode plate and a titanium roller in an electrolytic cell, wherein the electrolyte contains 150-200g / L of copper, and 90-110g / L of sulfuric acid; heating the electrolyteuntil the temperature reaches 48-55 DEG C; adding 50-80 parts, by mass, of polyethylene glycol with molecular weight of 6000 to the 1000 parts, by volume, of electrolyte per hour; adding 20 parts, bymass, of low molecular peptide with molecular weight of 3000 to 1000 parts, by volume, of electrolyte; adding 20-30ml of 17% hydrochloric acid to the electrolyte; uniformly stirring; and feeding the electrolyte into an anode tank. The novel root resisting electrolytic copper foil is uniform in structures of crystals on two surfaces, and the crystals on the two surfaces are regularly distributed; the thickness uniformity deviation of the novel root resisting electrolytic copper foil is less than 0.27 microns; the surface roughness Ra is 1.5 microns; the tensile strength is 380-450N / mm<2>; and the ductility is beyond 8.0%.

Description

technical field [0001] The invention belongs to the technical field of electrolytic copper foil production, and in particular relates to a process method of a novel electrolytic copper foil with a root-blocking copper base. Background technique [0002] Traditional waterproof membranes, ordinary polymer waterproof materials, and various waterproof coatings cannot meet the requirements of building planting systems, because these materials do not have root resistance and are easily penetrated by plant root tips, causing building damage and leakage , directly lead to the failure of the "building planting and greening" system. [0003] With the development of the national economy and the continuous growth of the construction industry, my country's building waterproof material industry has developed rapidly, new materials and new processes have been increasing, and production capacity has been significantly improved. The product quality of some key enterprises has approached or r...
