Modified alkyd resin for laminated board and preparation method and usage thereof

Abstract

The invention discloses a modified alkyd resin of laminated board, preparing method and usage in phenol resin domain, which is characterized by the following: adopting organic phenol monomer with linear hydrocarbon group and aldehydes monomer under the function of activator; getting the product; making the resin as transparent liquid with low viscosity and high dipping property; setting the number average molecular weight between 450 and 600 (GPC detection); decreasing evolution and discharge of free phenol effectively; adopting compatible diluent system. This resin possesses good storing stability, which is fit for dipping paper, cotton fabric and fiberglass cloth and so on reinforced materials.

Description

technical field

[0001] The invention belongs to the field of phenolic resins, in particular to a modified phenolic resin for laminates, a preparation method and application thereof. Background technique

[0002] In recent years, with the continuous expansion of the market for household and industrial laminates, the market demand for phenolic resin laminates, whether based on paper or cotton cloth and glass fiber cloth, is increasing.

[0003] Phenolic resin is a kind of synthetic resin that was first discovered and produced industrially. It has a wide range of raw materials, low price, high mechanical strength, hard wear resistance, heat resistance, flame retardancy, resistance to most solvents, and electrical insulation properties. Good advantages, so far, the impregnation resin used in the actual laminate production process is still mainly phenolic resin system. However, phenolic resin has fast curing reaction speed and poor storage stability, which brings certain difficu...
