Abstract
The invention relates to hard polyurethane foam with efficient flame retardant property, which is compounded by an intumescent flame retardant, a solid flame retardant and a liquid flame retardant in a multielement manner. The hard polyurethane foam is prepared by adopting the following steps: with polyether polyol, a catalyst, a foaming agent, a foam stabilizer, the intumescent flame retardant, the solid flame retardant and the liquid flame retardant as raw materials, mechanically stirring and mixing the raw materials at normal temperature according to a certain proportion, and mixing and foaming the raw materials with polyisocyanate to obtain the flame-retardant hard polyurethane foam finally.
Description
Technical field
The present invention relates to a kind ofly by expansion type flame retardant and the composite composition with highly effective flame-retardant characteristic of solid-state fire retardant, belong to the mode of utilizing the multiple material compounded combination and obtain the technical field with flame retardant properties material.
Background technology
Hard polyurethane foams (RPUF) because thermal conductivity is low, ultimate compression strength is high, light weight, cohesiveness be good, be easy to the series of advantages such as processing, therefore in construction wall energy-saving heat preserving field, have a wide range of applications; The alternative traditional inorganic heat insulation materials of polymer porous plastics such as employing urethane are widely used in building field has become one of important measures of various countries' sustainable development economy, save energy.
The hard polyurethane foam warming plate self is exposed to very easily burning under thermal source or burning things which may cause a fire disaster, and flame propagation velocity is very fast, and its LOI value is only 19.2%, and therefore, this material need to improve energetically its flame retardant properties when building field is further applied.
At present, two kinds of main paties of the inflammable problem of solution hard polyurethane foam warming plate are: one, by using fire retardant to carry out flame-retardant modified to the warming plate core; Two, by using the organic or inorganic fire retardant to do fire-retardant finish to the warming plate surface.
For example, number of patent application 201220017493.6 discloses a kind of six cladded type flame retardant polyurethane thermal insulating composite panels, and its characteristics are that its six faces are coated by fire-retardant cement-based interface felt, have surface flame-retardant performance preferably; Similarly, 201020232569.8 disclose a kind of waterproof thermal-insulated fireproof decorative integral board, and same effects on surface has been done fire-retardant finish.
The present invention mainly solves the inflammable problem in hard polyurethane foam surface by fire-retardant finish is done to flame retardant coating in the warming plate surface.
Summary of the invention
The present invention adopt expansion type flame retardant and solid-state fire retardant composite, after liquid adhesive fully mixes, be coated on hard polyurethane foam warming plate surface and prepare fire protection coating.
Raw materials used: hard polyurethane foam warming plate, expansion type flame retardant (technical grade), solid-state fire retardant (technical grade), liquid adhesive (technical grade).
For technical scheme of the present invention further is described, listed following detailed content:
