Description
Technical field
The present invention relates to a kind of composite and preparation method thereof, specifically a kind of hard bubbling for motor-car sealing strip
Polyurethane foam material and preparation method thereof.
Background technology
Motor-car sealing strip is mainly used in motor-car vehicle window, it may ensure that close between glass pane and the structural member of vehicle
Envelope so that can prevent the ambient influnence such as rainwater, dust and/or wind from entering vehicle interior.
Sealing strip material in the market is generally the materials such as polyvinyl chloride (PVC), vulcanization rubber, TPV：However, polychlorostyrene
Ethene (PVC) manufacturing procedure is complicated, and lower temperature resistance and resistance to ag(e)ing are poor, and feel is stiff under low temperature, influence sealing strip sealing effect
Really, PVC density is generally 1.15-1.20g/cm3, density is higher, in-convenience in use, especially in terms of smell and environmental protection by compared with
Big limitation, at relatively high temperatures, such as 50 DEG C or so will decomposite hydrogen chloride gas at leisure to polyvinyl chloride (PVC), processed
Foul smelling in journey, this gas is harmful, easily pollutes environment.Traditional vulcanization rubber processing complex procedures, basic working procedure
Including plasticating, kneading, roll or extrude, be molded and vulcanize, labor intensity is big, and plant equipment is numerous and diverse, due to addition carbon black,
The material such as the compounding ingredients such as accelerator, antiaging agent and framework material, vulcanization rubber belongs to the industry of heavy contamination, and smell is heavier,
Including the gas of the generations such as the not altogether clear refining glue of toxicity, vulcanization, plasticizing, there is different degrees of wound to human body
Evil.TPV thermoplastic dynamic perdurens, because TPV passes through sulfidation, so TPV has certain smell, it is impossible to meet current
The requirement of low smell.Except the requirement of environmental-protecting performance, special sealing strip fireproof security is also vital, is usually occurred
The situation of fire is easily triggered to occur when meeting with an accidet, it is therefore desirable to develop a kind of composite, the row of pernicious gas can be reduced
Put, can also improve fire resistance.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high, environmentally friendly the hard bubbling for motor-car sealing strip of fire resistance
Polyurethane foam material and preparation method thereof.
In order to solve the above-mentioned technical problem, the technical scheme that the present invention is provided is as follows：It is a kind of to be used for the hard of motor-car sealing strip
Polyurethane foam material and preparation method thereof is steeped, is made up of following quality proportioning component, isocyanates：Combination material=1：1.2, institute
The composition of combination material is stated based on following mass fraction, specific mass fraction is as follows：
Further, the silicone oil is silicone oil AK8802.
Further, the fire retardant is fire retardant TCPP.
Further, the isocyanates is TDI Tao Shi.
Present invention also offers a kind of preparation method of the hard-foam polyurethane expanded material for motor-car sealing strip, including with
Lower step：
A) combination material is prepared first：By polyethers HT-4110K, polyethers HS-3700, polyethers 3320, silicone oil, AFM180, water and
Fire retardant adds in reactor and carries out hybrid reaction, and mixing speed 100-120r/min, mixing time 8-9h can must combine material；
B) and then again by isocyanates with combining material by 1：1.2 mass ratio is well mixed, you can the foaming material is made
Material.
Beneficial effects of the present invention are as follows：
After above-mentioned material and method, because recipe ingredient collocation is reasonable and preparation method is proper so that preparation
Expanded material fire resistance is high, and chance fire is nonflammable, improves anti-flammability, and can reduce the discharge of pernicious gas, so as to protect
The security of vehicle is hindered.
