Problems solved by technology

Generally, the weight of foreign absorbent filter paper is as high as 360g / m2, and the thickness can reach 0.64mm. Due to the high price of foreign high-purity cotton pulp, the price of imported absorbent filter paper is as high as 100,000 yuan / ton, and the cost of use is high, which is not conducive to save resources
At present, domestic research on liquid-absorbing filter paper is still blank, and no manufacturer produces this liquid-absorbing filter paper.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The colloidal gold immune supporting water-absorbing material provided by the invention comprises the composition of the following weight percentages:

[0022] Wood fiber 20-80%;

[0023] Cotton fiber 10-40%;

[0024] Special fiber 10-40%.

[0025] In the colloidal gold immune supporting water-absorbing material provided by the present invention, the special fiber can be selected from corrosion-resistant fibers, specifically polytetrafluoroethylene fibers (Teflon TFE), tetrafluoroethylene-hexafluoropropylene copolymer fibers (TeflonFEP), One of polyvinylidene chloride fiber (Kynar) or ethylene-chlorotrifluoroethylene copolymer fiber (Halar) or their mixture.

[0026] The above-mentioned colloidal gold immunization supporting water-absorbing material, wherein, the special fiber can be selected from high temperature resistant fiber, specifically...

Abstract

The invention discloses a colloidal gold immune matched water absorbent material and a preparation method thereof. The water absorbent material comprises the following compositions in percentage by weight: 20 to 80 percent of wood fiber, 10 to 40 percent of cotton fiber and 10 to 40 percent of special fiber. By the colloidal gold immune matched water absorbent material and the preparation method thereof, different pulps are blended and subjected to wet papermaking by combining a fourdrinier former and an inclined wire former, so that the colloidal gold immune matched water absorbent material with relative low weight and high uniformity is produced, and the cost is greatly reduced on the premise of meeting the requirement on accuracy of test paper for quick detection.

Description

technical field [0001] The invention relates to a water-absorbing material and a preparation method thereof, in particular to a colloidal gold immune supporting water-absorbing material and a preparation method thereof. Background technique [0002] Currently, most immunoassays require expensive analytical equipment and instruments, and require professionals to operate the assay. Although these detection methods have high sensitivity and accuracy, they cannot meet the daily needs of people's health protection due to expensive equipment, inconvenient portability, and strong professionalism. The colloidal gold immunochromatography diagnostic technology solves the problem that has been puzzling people's rapid inspection, and the biological quick test strip filter paper is a supporting product for the colloidal gold immunochromatography of the immunological detection. [0003] Colloidal gold immunochromatography (GICA) is a new in vitro diagnostic technology developed on the ba...
