Problems solved by technology

[0004] At present, most of the wet rubbing fastness improving agents on the market are polyurethane types, which mainly have the following defects: First, the wet rubbing fastness improving agents have high production costs and large dosages, which have an impact on fabric color and physical and mechanical properties
Second, the synthetic raw materials of some wet rubbing fastness improving agents are highly toxic, and there are potential safety hazards in production, which do not meet environmental protection requirements
For example, water-based polyurethane wet rubbing fastness improver uses toluene-2,4-diisocyanate (TDI) as a synthetic raw material, and TDI is highly toxic and carcinogenic

Embodiment 1

[0031] The preparation of the copper microcapsule wet rubbing fastness improving agent of the present embodiment 1 may further comprise the steps:

[0032] (1) Weigh 100mL of 0.05mol / L γ-glycidyl etheroxypropyltrimethoxysilane into a four-neck flask, add 8.8gL-ascorbic acid and stir thoroughly (stirring speed 500 rpm) and heat up to 80°C, measure Put 200mL of 0.5mol / L copper sulfate pentahydrate in a separatory funnel, add 60 drops per minute at 80°C and continue to stir for 3 hours. After cooling down, 3.20g of reddish-brown copper nanometer powder is obtained. All the medicines are analytically pure, and the water used is distilled water;

[0033] (2) Grind the reddish-brown copper nanometer ultrafine powder collected in step (1), wash with distilled water twice, and then dry in an oven at 85°C for 2 hours;

[0034] (3) 1.00g of reddish-brown copper nanometer ultrafine powder dried in step (2), 0.50g of 2,2'-azobisisobutyronitrile, 0.25g of divinylbenzene, 26.75g of styrene...

Abstract

The invention relates to a preparation method and an apparition of a wet rubbing fastness improver containing copper microcapsules. The preparation method comprises the following steps: (1), silane modified ultrafine copper nanopowder is prepared; (2), the ultrafine copper nanopowder is ground and dried to constant weight; (3), the dried ultrafine copper nanopowder, 2,2'-azodiisobutyronitrile, divinyl benzene, butyl acrylate, methyl methacrylate and distilled water are mixed uniformly, tricalcium phosphate is added, and the mixture is subjected to ultrasonic vibration to obtain a dispersing liquid; (4) the dispersing liquid is placed into a flask with four necks to be subjected to heating, micro-suspension polymerization, heating and curing, and a product is washed with excessive hydrochloric acid solution and then washed to neutral to obtain the wet rubbing fastness improver containing the copper microcapsules. The prepared wet rubbing fastness improver containing the copper microcapsules can improve the wearability of fabric dyed with reactive dye, and the preparation method has the characteristics of simplicity, low cost, little time and labor investment, low toxicity of synthetic raw materials and reduction of environmental pollution.

Description

technical field [0001] The invention relates to a preparation method and application of a wet rubbing fastness improving agent containing metal copper microcapsules. Background technique [0002] Nano-materials such as copper powder, nickel powder and secret powder can be applied to lubricating oil additives, which can significantly reduce the friction coefficient of the object surface. Among them, nano-copper has a good lubrication function and has a good repair function on the surface of the worn object. [0003] When ultrasonic waves propagate in water, a series of effects will be produced. When high-power ultrasonic waves act on the solution, negative pressure will be generated in the solution, and the negative pressure will tear the liquid apart, resulting in empty holes. At this time, the empty holes are filled with thin gas or vapor, forming For the cavitation nucleus, under the vibration of the sound field, when the sound pressure reaches a certain value, the bubble ...
