Abstract
The present invention discloses a micro-fluidic chip mold, which adopts 30-50 parts by weight of a macromolecule polymer as a raw material, and further comprises, by weight, 10-15 parts of a filler, 1-3 parts of a plasticizer, 8-10 parts of gypsum, 3-5 parts of bamboo charcoal, 5-8 parts of aluminum powder, and 20-25 parts of iron powder. The micro-fluidic chip mold has the following beneficial effects that: the component matching is reliable and reasonable, the aluminum powder and the iron powder are added, the wear resistance and the strength of the micro-fluidic chip mold can be substantially enhanced, the service life of the mold can be effectively prolonged, and the production cost is substantially reduced.
Description
technical field [0001] The invention relates to a mold, in particular to a microfluidic chip mold. Background technique [0002] High molecular polymer is one of the most common materials for preparing microfluidic chips. Because high polymers have the characteristics of low material cost and processing cost, and are suitable for mass production and preparation, they are especially suitable for scientific basic research and development of microfluidic chips. There are two fields of production and application. The current processing methods for polymer microfluidic chips are mainly divided into direct processing methods and indirect processing methods. Among them, the indirect preparation method based on mold replication is the most important processing method for polymer chips. This method is especially suitable for The batch preparation of polymer chips therefore plays an important role in the industrialization of microfluidic chips. However, the current microfluidic chip...
