Abstract

The invention discloses a preparation method of a magnesia combined rosin modified phenolic resin composite heat insulating material, and belongs to the technical field of the preparation of high-temperature-resistant composite materials. The preparation method comprises the following steps of (1), putting organic silicon and magnesia into a sand mill and grinding; (2), crushing boron phenolic resin, adding ethanol and confecting to be boron phenolic resin glue liquor; (3), adding the organic silicon and the magnesia in the step (1) into the glue liquor in the step (2), adding a drier and uniformly agitating; (4), finally cutting PAN (Polyacrylonitrile)-based 1K plain carbon cloth into a cloth piece of 1,000mm*1,000mm, putting into mixed liquor which is uniformly agitated in the step (3) and placing at a ventilating and drying place; (5), cutting the dried cloth piece to be in a size of 200mm*200mm, putting into a baking box, pre-baking, taking out, then paving layers, carrying out die pressing and finally preparing to obtain a magnesia modified boron phenolic resin high-temperature-resistant composite material by adopting a lamination molding process. The preparation method has advantages that production raw materials are cheap and easily obtained, the emissions of the three wastes do not exist in industrial production, the ablation resistance is high, the mechanical performance is good, and the like.
