Abstract
The invention discloses a preparation technology of a polyurethane foam composite material with flame resistance. The preparation technology comprises the following steps: (1) polyether triols, a foaming agent, silicone oil, stannous octoate, sodium stearate, zinc stearate and water are added into a stirred tank for uniform stirring so as to obtain an A material; (2) polypropylene oxide, isocyanate, a fire retardant and water are added into another stirred tank for uniform stirring so as to obtain a B material; and (3) a mould is heated, a release agent is sprayed into the mould, and the A material and the B material are added into the mould for compression moulding by a press. Nano-magnesium hydroxide is used as the fire retardant, no pollution on the environment is caused, the preparation technology is simple, and requirements for equipment are low.
Description
Technical field
The present invention relates to the modification technology field of polyurethane foamed material, specifically a kind of preparation technology with polyurethane foam composite of flame retardant properties.
Background technology
Polyurethane foam is a kind of the components such as polyurethane prepolymer, whipping agent, catalyzer to be filled in to the special polyurethane products in withstand voltage inhalator jar, when material sprays from inhalator jar, the urethane material of foam shape can expand and form foam with the moisture generation curing reaction in air or the matrix that touches.Foam after solidifying has the multi-effects such as joint filling, bonding, sealing are heat insulation, sound-absorbing, is a kind of environmental protection and energy saving, material of construction easy to use, but is also a kind of extremely incendive material.The polyurethane foamed material great advantage is that light weight, heat-insulation and heat-preservation are good, sound insulation and buffering excellent in vibration resistance, has higher compressive strength and dimensional stability preferably.
