Embodiment 1

[0019] Negative ion surface treatment agent, according to the following ratio:

[0020]

[0021] The production technology of multifunctional water-based leather surface treatment agent comprises concrete steps as follows:

[0022] Preferably, the drying temperature of the oven is 50° C. to 200° C., multi-stage temperature control is implemented, and the temperature is raised in stages.

[0023] The raw materials except the thickener are added into the container in sequence, stirred evenly with a disperser, the stirring speed of the disperser is 500-2900 rpm, after filtering, the thickener is added to adjust the viscosity to obtain a topical agent.

Abstract

The invention discloses a formula for a multifunctional surface treating agent applied to aqueous leather. The formula comprises 3 to 35% of an aqueous polyurethane emulsion, 0.5 to 20% of a multifunctional finishing agent, 2 to 15% of aqueous wax, 0.3 to 3% of a leveling agent, 0.5 to 1.5% of a thickening agent, 0.5 to 1% of an antifoaming agent and 24.5 to 93.2% of water. The preparation processcomprises the following steps: adding all the above raw materials except the thickening agent into a container in proportion, carrying out uniform mixing through a dispersator, then carrying out filtering and adding the thickening agent to adjust viscosity so as to obtain the surface treating agent. The surface treating agent provided by the invention endows synthetic leather with special performances like antibacterial, sterilizing, anti-ultraviolet, anti-radiation, flame-retardant, temperature-adjusting, color-changing, self-cleaning and anti-doodling performances without any influence on the fastness and handfeel of the synthetic leather, and substantially prolongs the service life of the synthetic leather; a product having been treated with the surface treating agent has better handfeel and presents better visual impression; and the surface treating agent greatly improves the physical properties of the synthetic leather and allows the synthetic leather to have more excellent scrape resistance, water resistance, fire resistance and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of water-based synthetic leather surface treatment agents, in particular to the technical field of the formulation and process of a multifunctional water-based leather surface treatment agent. 【Background technique】 [0002] As a major producer of artificial leather and synthetic leather, my country is facing increasing pressure while the output of enterprises and total industrial output value are growing steadily, especially for exporting to the European market. The European Chemicals Agency officially announced the eighth batch of candidate list of substances of very high concern, including N,N-dimethylformamide (DMF). The promulgation of this regulation has once again put forward a severe test for synthetic leather manufacturers. [0003] It has become a development trend for water-based synthetic leather to replace traditional oil-based synthetic leather. Therefore, the finishing technology related to...
