Abstract

The invention discloses tyrosine-based thermosetting phenolic resin with a biological adhesion resisting function, which comprises the following components in parts by weight: 0-6 parts of tyrosine or tyrosine derivatives, 4-10 parts of phenolic compounds and 8-14 parts of paraformaldehyde, wherein the relative molecular mass of paraformaldehyde is 90.08 g / mol; the ortho-position or para-position of the phenolic hydroxyl group of the phenolic compound is not occupied by other functional groups; the molar ratio of phenol to aldehyde is (1: 1.7)-(1: 2.2). The invention also provides a preparation method of the tyrosine-based thermosetting phenolic resin and application of the tyrosine-based thermosetting phenolic resin in an antifouling coating. The biological adhesion resistant phenolic resin material can be prepared and can be combined with other resin coatings for use, the raw materials are green and environment-friendly, the synthesis is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of antifouling materials, in particular to a tyrosine-based thermosetting phenolic resin with anti-biological adhesion function, a preparation method and application thereof. Background technique [0002] As one of the three thermosetting resins, phenolic resins have a long history of development and are widely used. With the advantages of high temperature resistance, high rigidity, corrosion resistance and less smoke, it has been widely used in transportation, construction, military industry, electronics and other fields. At present, phenol, one of the raw materials of phenolic resin, is extracted from petroleum. However, petroleum is a non-renewable natural resource, so phenol is unsustainable and toxic. Due to concerns about environmental and resource sustainability, there is an urgent need to find a safe and green phenolic compound to replace phenol to synthesize new phenolic resins and endow them with ...
