Abstract

The invention discloses a thermosetting phenol resin which comprises in parts by weight of: 30 parts of phenol; 10-15 parts of formaldehyde; 10-15 parts of ethyl alcohol; 5 parts of tritolyl phosphate; 1-3 parts of boron compound; 1 part of polysiloxane; 0.2 part of antiager TCY2-3; 10 parts of fillers; 0.1-0.5 part of antioxidant; 1-3 parts of catalyst and 1.5 parts of surface-active agent. The tritolyl phosphate and the boron compound are added in the preparation of the phenol resin, increasing the corrosion resistance of the phenol resin. Meanwhile, the addition of the antiager increases the tenacity of the phenol resin. In the invention, the preparation process is simple and can be controlled easily and convenient for production.

Description

Technical field [0001] The present invention involves a thermosethel phenolic resin, which belongs to the field of polymer material technology. Background technique [0002] Universal plastic applications are in high -end fields such as engineering industry and national defense technology, such as automobiles, aerospace, construction, communications and other fields.Plastic can be divided into thermoplastic plastic and thermal solid plastic according to its peratable classification.Under normal circumstances, thermoplastic plastic products can be recycled, while thermosetry plastic cannot.Thermosetry plastic made of phenolic resin as the main raw material, such as phenolic mold pressure plastic (commonly known as electric wood), has the characteristics of strong durability, stable size, and other chemicals other than strong alkali.The preparation process control is complicated and is not easy to produce.
