Abstract

The invention discloses an environmental protection modified melamino-formaldehyde melamine resin foam material and a preparation method. The environmental protection modified melamino-formaldehyde melamine resin foam material is prepared from the following raw materials in parts by weight: 65-80 parts of modified melamino-formaldehyde melamine resin, 3-6 parts of a foam stabilizer, 0.2-2 parts ofa foaming agent, 20-35 parts of a functional powder material, 0.2-0.5 part of a dispersant, 0.3-0.6 part of an accelerant and 2-5 parts of a curing agent. According to the environmental protection modified melamino-formaldehyde melamine resin foam material, the modified melamino-formaldehyde melamine resin serves as a main material, through addition of the functional powder material, the cost islowered, the strength is improved, and shrinkage is reduced, the percentage of close area of the foam material is increased, and the flame retardant property is improved; a method combining chemical and physical foaming is adopted, meanwhile a self-developed efficient HCGP-MW foam stabilizer is used, the foam stabilizing time is long, the percentage of close area is high (larger than or equal to 96%), and thus the foam material is light in weight, high in strength, and efficient in heat insulation; and the prepared environmental protection modified melamino-formaldehyde melamine resin foam material can be normally used in -60 DEG C-180 DEG C of the high-low temperature corrosive environments for a long time.

Description

technical field [0001] The invention relates to the technical fields of polymer materials, composite materials, anti-corrosion, high temperature resistance, flame retardant, heat insulation, heat preservation and new materials, in particular to an environmentally friendly modified melamine-formaldehyde melamine resin foam material and a preparation method thereof. Background technique [0002] Melamine formaldehyde melamine resin has excellent water resistance, heat resistance, aging resistance, chemical corrosion resistance, flame retardant and insulation properties, as well as high gloss, high wear resistance, high hardness and other characteristics, and it is non-toxic after curing, and can be widely used Used in the manufacture of molding compounds (daily tableware, electrical appliances), wood-based panels (plywood, reinforced wood panels, and laminated plastic panels), etc., in addition to being widely used as coatings, paint crosslinking agents, wood adhesives, paper ...
