Abstract: A plugging material is prepared from the following raw materials in terms of mass fractions, which include: 1 to 3.6 parts of PETA-modified bisphenol A epoxy resin, 1.5 to 2.4 parts of addition product of m-phenylenediamine and methacrylic acid, 0.12 to 0.17 parts of nanosilica dispersion liquid, with the remainder being water, such that the sum of the mass fractions of the aforementioned raw materials totals 100 parts. The preparation method includes: pouring a water phase mixture into a continuously stirred oil-phase mixture to form a gel-forming liquid through continued stirring; transferring the gel-forming liquid to be mixed with dibenzoyl peroxide, and stirring and reacting at a temperature of 50° C. to 120° C. to obtain the plugging material. The plugging material is resistant to high temperatures and high salinity, and exhibits strong plugging performance.

Abstract: Disclosed is a test paper for detection of diabetic nephropathy, which includes a water-absorbing filter paper, a glass fiber membrane and a NC membrane, all of which are stacked successively from top to bottom. The test paper has a T1 testing region, a T2 testing region and a T3 reference region arranged along a transverse direction; the NC membrane is coated by urinary microalbumin antibodies in the T1 testing region, is coated by urinary haptoglobin antibodies in the T2 testing region and is coated by mouse anti-human IgG antibodies in the T3 reference region; and the glass fiber membrane is coated by urinary microalbumin labeled with colloidal gold in the T1 testing region, is coated by urinary haptoglobin labeled with colloidal gold in the T2 testing region and is coated by mouse anti-human IgG albumen labeled with colloidal gold in the T3 reference region.
