Description
Technical field
The present invention relates to polyether silicones synthesis technical field, specially a kind of polyethers with good emulsifiability is organic
Siliceous copolymer and synthetic method and application.
Background technique
Polyurethane foam plastics is a kind of important synthetic material, and with porosity, relative density is small, specific strength is high, excellent
Good physical mechanical property, acoustical behavior, electric property and chemical-resistance.According to the change of raw materials used difference and formula
Change, polyurethane foam plastics can be made into soft, semi-rigid and rigid polyurethane foam.Polyurethane foam plastics is by a variety of originals
Material is chemically reacted in a short time (such as isocyanates, polyalcohol, foaming agent etc.), and colloid is become by liquid and is become again
High polymer experiencings the complex processes such as foaming, gel therebetween.
It in entire chemical reaction process, is acted on by polyurethane foam stabilizer, just uniform in foaming, foam can be made steady
It is fixed, the foams of uniform foam cell are made.Its role mainly has:
(1) each component in emulsion foam system.The intermiscibility of each component in foam formulation is poor, foam stabiliser tool
There is the molecular structure of amphipathic (oleophylic/hydrophilic), it can be made to be uniformly mixed with emulsion foam raw material, before improvement material reaction, instead
Compatible state in answering, so that foamable reaction and cross-linking reaction be made to go on smoothly.
(2) nucleation and stable foam.Since foam stabiliser can reduce the surface tension of material, when stirring, is easy to make to mix
The air entered forms nuclei of bubbles, these nuclei of bubbles play the role of similar " nucleus ", and the gas for reacting generation enters nuclei of bubbles simultaneously
Bubble is set constantly to grow up；In foaming process, foam stabiliser makes the cell wall of thinning by reducing the stress in cell wall
Stablize, being uniformly distributed makes fizzy, collapse hole without causing foam aperture to merge with macropore.
(3) closed pore/aperture effect.It is good exhausted that rigid polyurethane foam abscess closed pore can just be such that foamed product has
Thermal effect and enough mechanical strengths, foam stabiliser obtain uniform foam cell by the way that the surface tension of foaming system is effectively reduced
Fine and closely woven and rate of closed hole is higher than 95% foams, to guarantee foam thermal insulation performance.The abscess of flexible polyurethane foam is necessary
It is aperture can just make product soft and springiness.Due to the effect of foam stabiliser, when system is in the low viscosity stage,
Cell wall is stablized, and when air bubble growth is to the thickness for being suitable for aperture, the abscess under the collective effect of catalyst and foam stabilizer
Rupture is " aperture ".The defects of foam stabiliser can be by controlling the foamed open cell time, eliminating foam cracking, closed pore, assigns
The good air penetrability of foam and comfort property.Therefore foam stabiliser not only plays even bubble, and to the bubble of polyurethane foam
The properties of product such as pore structure, intensity, thermal coefficient, air penetrability have an important influence, and play irreplaceable role.
For polyurethane foam stabilizer mainly using siloxanes segment as hydrophobic group, polyether segment is that hydrophilic group passes through chemical bond
Be formed by connecting polyether silicones copolymer.
