Abstract
Latex spray foams formed from a two-part foamable composition are provided. The A-side contains a functionalized latex and an acid and the B-side contains a polyfunctional aziridine crosslinking agent, a plasticizer, a base, and, optionally, a non-functionalized resin. The acid and the base form a blowing agent package that when mixed, react to form a gas. The A- and B-side also contain thickening agents. The polyfunctional aziridine crosslinking agent is diluted by a plasticizer, which reduces the viscosity of the B-side and reduces the amount of ethyleneimine, a toxic component in the polyfunctional aziridine crosslinking agent. The presence of a plasticizer also permits the inclusion of other materials that may add functionality and/or cost savings to the foamed product. The plasticizer should have no acidic protons to react with the crosslinking agent. When no acidic protons are present, the B-side is stable for extended periods of time.
Description
Technical field of the present invention and industrial applicibility
The present invention relates generally to foam, relates more particularly to by having two portions spraying foam that A side that comprises latex and the foamable composite that comprises the B side of polyfunctional aziridine linking agent and softening agent form.This foam is used for cavity filling, crack and slit sealing and the insulating property with enhancing buildings, car and utensil, and is that carpet, liner, mattress, bolster and toy form backing.This foamy preparation method also is provided.
Background technology
The spraying foam has been widely used in insulation and the structure enhanced field.For example, the spraying foam is generally used for making object (for example automobile, heat channel, electricrefrigerator, ship and building structure) insulation or introduces structural strength for it.In addition, the application below the spraying foam for example is used for: be used for the liner of furniture and bed accessory, the bedding and padding that are used for carpet lower floor, sound absorbent material, fabric laminate products and energy-absorbing material.At present, the spraying foam especially as the insulating compound of home wall or those foams of sealing agent, is a urethane spraying foam.
Urethane spraying foam and preparation method thereof is known.Usually, urethane spraying foam is to be formed by two kinds of components of separating, so-called " A " side and " B " side, and it reacts when contacting with each other.First component, or " A " side comprise isocyanic ester, for example on molecule, have two or POLYMETHYLENE POLYPHENYLISOCYANATE of high NCO (nitrogen, carbon and oxygen) functional group's per-cent.Second component, or " B " side comprise nucleophilic reagent, for example comprise two or more than polyvalent alcohol, siloxanes tensio-active agent, whipping agent, catalyzer and/or other auxiliary agents of two hydroxyls.This nucleophilic reagent is polyvalent alcohol, primary and secondary polyamines and/or water normally.Preferably, the mixture that uses two pure and mild triols is to reach required foam properties.Total hydroxyl value of design polyvalent alcohol is to reach 1: 1 first component: the second ratio of component (A: B).
Usually these two kinds of components are transported in the spray gun (for example collision type spray gun) through the pipeline that separates.This first and second component is passed through aperture to form single component logistics separately with the high pressure pumping.The logistics of this first and second component intersects and is mixed with each other in this rifle, begins reaction.Reaction heat makes that the temperature of reactant raises in this first and second component.The rising of this temperature causes the whipping agent evaporation that is arranged in second component (" B " side) and forms foam mixture.Along with this mixture leaves this rifle, this mixture contacts with the surface, with its adhesion, and continues reaction till the isocyanate groups complete reaction.Resulting heat transmission resistance or R value can be the 3.5-8/ inch.
