Description

A kind of method and microballoon foaming agent that microballoon foaming agent is prepared using spray-on process
Technical field
The present invention relates to foaming agent technical field, more particularly to a kind of method that microballoon foaming agent is prepared using spray-on process And microballoon foaming agent.
Background technology
The foaming agent that heat-expandable microsphere includes the shell of thermoplastic resin and is encapsulated in shell, commonly referred to as heat is swollen for it Swollen property micro-capsule.Thermoplastic resin generally includes vinylidene chloride based copolymer, acrylic copolymer and acrylate copolymer. The foaming agent mainly used includes hydrocarbon, such as iso-butane and isopentane.Thermal expansion foam microspheres have excellent foam performance, excellent Good solvent resistance, wearability, electrical insulating property, the advantages that good mechanical performance and nontoxic pollution-free, available for coating, spin Knit, plastic processing, adhesive, sealing ring, synthetic leather, insulation, the field such as lightweighting materials.In such microballoon, foaming agent leads to It is often the liquid that boiling temperature is not higher than thermoplastic polymer shell softening temperature.Once heating, foaming agent evaporates and increases internal pressure, At the same time, housing softens, so as to cause the microballoon significantly to expand.
Expandable microspheres are prepared using suspension polymerization substantially both at home and abroad at present.Suspension polymerisation will be by that will include foaming agent and gather The polymerizable compound for closing monomer is dispersed in incompatible liquid such as water and forms shell, and shell is to wrap up the thin layer form of interior foaming agent Formed.In process for suspension polymerization, foaming agent and polymerizable compound including polymerisable monomer are by continuously stirring or adding The stabilizer such as magnesium hydroxide or cataloid and keep suspended state.By suspension polymerisation, polymer can be formed It is spherical.
US 20110123807 proposes a kind of preparation method of the thermal expansion type foam microspheres with core shell structure, with foaming Agent is core, and long-chain crosslinking agent of the number-average molecular weight having using thermoplastic resin and between crosslink sites more than 500 is shell.Should Method can increase the viscosity of monomer and blowing agent blends, prepare the thermal expansion type microballoon with homogeneous diameter.But propylene The addition of esters of gallic acid long-chain crosslinking agent, adds the crosslink density in sheath polymers strand, improves the mechanical strength of shell, But foam stabilizing temperature range is also reduced simultaneously.
US7931967B2 prepares a kind of thermal expansion type in the presence of polymerizable organo-silicon compound with suspension polymerization Microballoon, shell composition includes polymerisable monomer copolymer and organo-silicon compound, by shell layer surface silicone functionalities to nothing The adhesive force of machine particle, a certain amount of inorganic particulate is adhered to by chemical bond in microsphere surface, avoids foam microspheres particle from making Caused agglomeration traits in standby process and foaming process.But cost of material is added using polymerizable organo-silicon compound, is influenceed The polymerisation of acrylate monomer, the inorganic particulate of microsphere surface bonding influence the purity of microballoon.
Suspension polymerisation uses HTHP polymerization technique, but these preparation methods have the following disadvantages:Equipment investment is big, instead High energy consumption is answered, polymerization exotherm easily makes the boiling vaporization of low boiling point hydrocarbon foaming agent under the high temperature conditions, is not easy processability stabilization Foam microspheres and processing safety is low, environmental requirement is tight, and production cost is difficult to control.
The content of the invention
It is big that the equipment investment of microballoon foaming agent is prepared for current suspension polymerisation, energy consumption of reaction is high, gathers under the high temperature conditions Closing heat release easily makes low-boiling foaming agent boiling vaporization, is not easy the stable foam microspheres of processability and processing safety is low, environmental protection It is required that tight, the shortcomings that production cost be difficult to control, microballoon foaming agent is prepared using spray-on process it is an object of the invention to provide a kind of Method and microballoon foaming agent, it has equipment simple, and technique is more environmentally friendly, and production cost is easily controlled, produce controllability The advantages of higher.
