Abstract

The invention discloses a modified urea-formaldehyde resin composition which comprises urea-formaldehyde resin, weather resistance agent, stabilizer, filler, high temperature resistance agent and flame retardant, wherein the weather resistance agent is composed of 2-hydroxy-4-n-octanoyldiphenyl ketone; the stabilizer is composed of di-n-octyltin moleate; the filler is composed of carbon fiber; the high temperature resistance agent is composed of epoxy resin; and the flame retardant is composed of aluminum hydroxide. According to the modified urea-formaldehyde resin composition, the prepared modified urea-formaldehyde resin has the effects of no toxicity, favorable toughness, favorable weather resistance, stable molding and the like.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a formula of modified urea-formaldehyde resin. Background technique [0002] Urea-formaldehyde resin can be used to manufacture tableware, bottle caps and other daily necessities and mechanical parts, and can also be used as an adhesive. Urea-formaldehyde resin is a colorless plastic that can be used as molding material, adhesive, etc., and is prepared from urea and formaldehyde. The urea-formaldehyde resin molding compound is filled with cellulose. Furthermore, it is excellent in hardness and mechanical strength. However, it has the disadvantages of brittleness, water absorption, and poor dimensional stability, and cracks often occur even when it is left standing. Contents of the invention [0003] The purpose of the present invention is to provide a non-toxic, good toughness, good weather resistance and excellent stability of the formula of modified urea-formaldehyde resin. [0004] T...
