Abstract

The invention discloses plant oil filter paper, which is prepared from the following components in parts by weight: 10 to 80 parts of bast fibers, 30 to 80 parts of bamboo fibers, 10 to 50 parts of ceramic fibers, 1 to 20 parts of a fibrous adhesive, 0.1 to 5 parts of a dispersing agent and 5 to 20 parts of cellulose nanocrystals. The plant oil filter paper has the characteristics of high temperature resistance, high average void fraction, high filtering absorption performance, long service life, strong wet-and-dry strength and uniformity. The invention further provides a preparation method for the plant oil filter paper.

Description

technical field [0001] The invention relates to the technical field of filter paper, in particular to a vegetable oil filter paper and a preparation method thereof. Background technique [0002] Vegetable oil filter paper is mainly used to filter crude oil and refined oil in the process of vegetable oil processing and production. It can clarify, decolorize, purify, filter out suspended solids, colloidal impurities, phospholipids, heavy metals, etc. in oil, and separate solid and semi-solid impurities. Generally, it is mainly used in edible frying oil filter machines. Because the filter paper has adsorption and supports the adsorbent, it can absorb and filter out impurities such as suspended solids and harmful compounds in high-temperature frying oil, and fundamentally reduce the chance of oil deterioration. Inhibit the growth of acid value, prolong the service life of frying oil, and make the frying oil clear and transparent. [0003] Therefore, vegetable oil filter paper n...
