Abstract

The invention discloses a modified environment-friendly phenolic aldehyde thermal insulation material and a preparation method thereof. The method comprises the following steps of: sufficiently mixing 100 parts of resole, 5-15 parts of sodium sulfite, 10-30 parts of phenolsulfonic acid solution, 2-5 parts of stabilizer, 1-8 parts of nano calcium carbonate, 1-8 parts of calcium sulfate whisker, 0.1-3 parts of nano aluminum hydroxide, 0.1-3 parts of ethylene glycol and 15-30 parts of foaming agent by weight; uniformly spreading the mixture on a plane carrier; and uniformly heating through a lamination conveyor and performing foaming and curing molding. According to the invention, sodium sulfite and phenolsulfonic acid solution are used as composite catalysts; and since the sodium sulfite has the effects of deoxidizing and reducing the acidity of the mixed solution, under the joint effect of the sodium sulfite and phenolsulfonic acid solution, the corrosion of the phenolic aldehyde thermal insulation material on a metal component is avoided. The modified phenolic aldehyde thermal insulation material disclosed by the invention is far superior to the values stipulated by the national standard in terms of the indexes such as compression strength, bending strength, creep resistance, dimensional stability, water absorption and the like; and the corrosion on metals is obviously reduced in comparison with a common product.

Description

technical field [0001] The invention relates to a phenolic thermal insulation material and a preparation method of the material. Background technique [0002] Phenolic insulation material is a closed-cell rigid foam made of phenolic resin with foaming agent, curing agent and other additives. It has excellent thermal insulation performance and fireproof performance, and is widely used in building insulation, pipeline insulation and other occasions. The phenolic insulation material overcomes the shortcomings of the original foam plastic insulation material, such as flammability, smoke, and heat deformation, and retains the original foam plastic insulation material's light weight and convenient construction. However, the existing phenolic insulation materials have disadvantages such as easy corrosion of metal components, low strength, and easy pulverization during use. [0003] At present, the technical improvement of phenolic insulation board in the market mainly lies in imp...
