Abstract
A single-component foam polyurethane material contains prepolymer and propellant, and is prepared through mixing isocyanate with polyether in mole ratio of (1.05-1.25):1 under protection of nitrogen gas in sealed reactor with reflux unit, stirring, raising temp, constant-temp reaction at 80-125 deg.C for 1-1.5 hrs, pouring into cans, injecting propellant and sealing. Its advantages are convenient application, high performance and nearly no environmental pollution.
Description
The present invention relates to a kind of foam material and manufacture method thereof that is used for the building decoration field, be particularly related to a kind of polyurethane foam material and manufacture method thereof, can be used in the building decoration filling, aspects such as damping in bonding, insulation, waterproof, insulation and the packed and transported, buffering.
The existing polyurethane foam material that is used for architectural decoration generally adopts isocyanic ester and the two component in-situ sprayings of polyethers or injects foaming and makes, as " polyurethane foam material technology is to the influence of end properties " that the last 11-18 of " electronics manufacturing engineering " nineteen ninety-five the 1st volume published on the phase, free isocyanate monomer wherein has stronger toxicity.Present stage often adopts fluorine Lyons compounds to make whipping agent simultaneously, " 5103 low fluorine Lyons polyurethane foam material " of recruiting foam material factory to declare as Wuxi City section in " national product innovation storehouse ", to the harm of human body and seriously polluted to environment, and having relatively high expectations to execution conditions and personnel.
The purpose of this invention is to provide a kind of single-component foam polyurethane material and manufacture method thereof.This foam material adopts the form of aerosol, and whipping agent is airborne moisture, adopts non-cfc class propellent, owing to be the performed polymer of single component, do not contain the free isocyanate-monomer in the system, so toxicity is minimum, environmentally safe, easy to operate, be easy to carry.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of single-component foam polyurethane material comprises performed polymer, propellent that isocyanic ester and polyethers hybrid reaction obtain.
A kind of method of making single-component foam polyurethane material; isocyanic ester and polyethers are taken back in the reactor that flows device airtight; press 1.05-1.25 under the nitrogen protection condition: 1 mixed in molar ratio; stir and heat up; between 80-125 ℃ isothermal reaction 1-1.5 hour; in vacuum tank installation, carry out cannedly then, charge into propellent, pack and get product.
High expandable polyurethane foamed glue of the present invention, need only one press gently, performed polymer mixture and propellent in the jar can be sprayed together, the micro-moisture that exists in air can make the rapid curing cross-linked of system, and emit carbonic acid gas, carbonic acid gas and propellent are with advancing to make its foaming and intumescing, and be easy to use, and human body and environment are existed harm and pollution hardly, time saving and energy saving, excellent property, according to detection: expansion multiple be 30-60 doubly, surface drying time is 6-15 minute, the completely solidified time is 1-3 hour, cohesive strength is more than or equal to 800 kPas, and ultimate compression strength is more than or equal to 50 kPas, and shearing resistance is more than or equal to 600 kPas.
The present invention is further detailed explanation below in conjunction with embodiment:
Implement 1, with diphenylmethanediisocyanate and glycerol polyethenoxy ether mixed in molar ratio by 100: 83, stirred 2 hours at 80 ℃ of following constant temperature, stopped reaction and with the system cool to room temperature, press the triethylene diamine catalyzer of mass ratio adding 2%, 1% organic silicone suds-stabilizing agent, 2% aluminium hydroxide and 1.5% weisspiessglanz compound fire retardant, at room temperature stirred 50 minutes, in the vacuum tank installation, carry out canned then, charge into propellent, propellent can adopt liquefied petroleum gas (LPG), the mass ratio of propellent and content is 1: 2, gets product after the sealing, and the gained finished product is a flame-retardant polyurethane single-component foamed glue.
Embodiment 2, with the polymethine polyphenyl polyisocyanate, sorbyl alcohol polyethers and glycerin polyether are pressed 100: 80: 10 mixed in molar ratio, stirred 1.5 hours at 90 ℃ of following constant temperature, stopped reaction and with the system cool to room temperature, press the triethylene diamine of mass ratio adding 2.5%, 0.5% stannous octoate, 1.5% organic silicone suds-stabilizing agent, 2% aluminium hydroxide and 1.5% weisspiessglanz compound fire retardant, 0.1% 2.6-d-tert-butyl-p-cresol anti-aging agent, at room temperature stirred then 40 minutes, in the vacuum tank installation, carry out canned then, charge into propellent, propellent is a dme, the mass ratio of propellent and content is 1: 2, gets product after the sealing.
