First, it should be noted that, in the drawings, the same components or parts have the same reference numerals as much as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

1 is a schematic view illustrating a process for producing an asphalt modifier according to an embodiment of the present invention.
The asphalt modifier according to the present invention relates to an asphalt modifier which can be added to a waterproofing material, a waterproof sheet and the like containing asphalt to improve performance.
The present invention relates to a process for producing a polyurethane foam comprising 95 to 50% by weight of a chlorinated paraffin plasticizer and 5 to 50% by weight of a plasticizer containing at least one of diisononyl phthalate, soybean oil and soybean oil, 5 to 30% by weight of a polyolefin resin, 5 to 20% by weight of a C5 to C9 petroleum resin, 5 to 20% by weight of an ethylene methyl acrylate copolymer 5 Wherein the mixing ratio of the first mixing portion to the second mixing portion is from 1 to 20% by weight, the polyethylene graft maleic anhydride is from 5 to 20% by weight, and the polyethylene wax is from 1 to 15% 1 mixed portion: the second mixed portion is 50 to 95: 5 to 50 weight ratio.
Also, the process for producing the asphalt modifier of the present invention may be carried out by mixing and stirring a chlorinated paraffin plasticizer with a plasticizer containing at least one of diisononyl phthalate, soybean oil and soybean oil and stirring at 70 to 100 ° C for 3 to 5 hours to prepare a mixture A first mixing part manufacturing step; And a second mixing part manufacturing process at 150 to 190 캜 with a twin-screw extruder in combination with a chlorosulfonated polyethylene synthetic rubber, a polyolefin resin, an ethylene methyl acrylate copolymer, a polyethylene graft maleic anhydride, and a polyethylene wax, 2 The first mixing part can be manufactured by stirring the mixture at 70 to 120 ° C for 30 minutes to 2 hours.
95 to 50% by weight of the first mixed chlorinated paraffin plasticizer and 5 to 50% by weight of a plasticizer containing at least one of diisononyl phthalate type, soybean oil and soybean oil.
The chlorinated paraffin-based plasticizer serves to disperse the synthetic rubber and the polyolefin-based resin.
The chlorinated paraffinic plasticizer is preferably a liquid plasticizer having a specific gravity of 1.1 to 1.3, a chlorine content of 30 to 50% and a viscosity of 4 to 9 cps (test conditions: kinematic viscosity at 60 캜). This is because it affects the compatibility with asphalt. When the specific gravity is low, the physical property is decreased. When the chlorine content is adjusted upward by more than 50%, the tacky property is overcome and serves as a phase separation element with the base, and the chlorine content is less than 30% It is difficult to use it in products because it has weak adhesive force. When the viscosity is less than 4 cps, the dispersibility decreases. When the viscosity exceeds 9 cps, the viscosity difference with the base occurs and the miscibility becomes poor.
The first mixing part is mixed with a plasticizer containing at least one of diisononyl phthalate, soybean oil, and soybean oil as a plasticizer, which is an eco-friendly plasticizer and has an advantage of increasing the flash point when mixed. The processing temperature of the asphalt is about 150 캜. In this case, chlorine gas is generated. Therefore, it plays a role of raising the flash point by mixing a plasticizer containing at least one of diisononyl phthalate type, soybean oil and soybean oil, thereby suppressing the generation of chlorinated gas.
The plasticizer containing at least one of the diisononyl phthalate type, soybean oil and soybean oil preferably has a specific gravity of 0.92 to 0.98 and an ester content of 99% or more. The soybean oil and soybean oil used to solve the problem of raising the flash point are higher as the purity is higher because they act as plasticizers for increasing the mutual miscibility of SBS and ethylene methyl acrylate copolymer, To 0.98.
The first mixture may be stirred at 70 to 100 ° C for 3 to 5 hours to prepare a liquid mixture.
In the present invention, it is preferable that the second mixing portion comprises 5 to 35 wt% of a chlorosulfonated polyethylene synthetic rubber, 5 to 30 wt% of a polyolefin resin, 5 to 20 wt% of a C5 to C9 petroleum resin, 5 to 20% by weight, polyethylene graft maleic anhydride 5 to 20% by weight, and polyethylene wax 1 to 15% by weight.
The chlorosulfonated polyethylene synthetic rubber preferably has a chlorine content of 30 to 50% and an elongation of 700% or more. Polyethylene synthetic rubber, which improves the impact strength, is highly elastic due to its high elongation, and affects the overall crystallinity by decreasing the content of chlorine. Therefore, products with viscoelasticity with an optimum ratio of 30 to 50% The elasticity and heat resistance of the modifier can be secured at the same time.
The polyolefin-based resin preferably has a melt index of 3 to 6 (190 캜 / 2.16 kg), a specific gravity of 0.88 to 0.91, and a melting point of 100 to 106 캜. When a polyolefin resin has a melt index of 3 to 6 (190 ° C / 2.16 kg), which is close to the overall target value, a similar miscibility with respect to the entire product is formed, and a product having a low specific gravity and a heat resistance of 90 ° or more must be used. It is suitable for use as an asphalt modifier.
The C5 to C9 petroleum resin preferably has a specific gravity of 1.0 to 1.2, a softening point of 95 to 105 ° C, and an acid value of 0.05 or less. As the length of the carbon chain increases, the mechanical properties of the petroleum resin increase but the tacky property decreases. C5 ~ C9 petroleum resin has a specific gravity of 1.0 ~ 1.2, softening point of 95 ~ 105 ℃ and acid value of less than 0.05 because the most important role of tackifier and softening point is to have heat resistance over 90 ℃. Can be given at the same time.
The ethylene methyl acrylate copolymer is preferably mixed with two different ethylene methyl acrylate copolymers having a viscosity of 0.5 to 6 cps (test condition: kinematic viscosity at 60 캜) and a specific gravity of 0.90 to 0.95. Ethylene methyl acrylate has both heat resistance and unit cost factors, and is also excellent in chemical performance and weatherability. The ethylene methyl acrylate copolymer has miscibility with the asphalt modifier at the most suitable level in the range of 0.5 to 12 cps (test condition: 60 ° C kinematic viscosity). When the specific gravity of the ethylene methyl acrylate copolymer is high, the specific gravity is preferably 0.90 to 0.95 in order to increase the unit factor and the overall specific gravity.
The polyethylene grafted maleic anhydride preferably has a specific gravity of 0.90 to 0.93 and a viscosity of 0.5 to 2. In the case of polyethylene grafted maleic anhydride, it acts as a coupling agent to increase the bonding force between the crystalline polymer (LDPE series / LLDPE, PE base polymer, other crystalline region) and the amorphous polymer (rubber type) , The mechanical properties of the polar polymer, and the miscibility, and the viscosity is low, and it is preferable to add the polymer within 5 to 10%. When the specific gravity is very low, the degree of improvement in the physical properties is low and the specific gravity is preferably 0.90 to 0.93.
The polyethylene wax preferably has a specific gravity of 0.89 to 0.92 and a melting point of 100 to 120 ° C.
The polyethylene wax has a property of rapidly decreasing the viscosity at a temperature above the melting point, so that the processability is improved when the modified wax is processed into a modifier, and the meltability and the mixing property of the modifier can be improved when mixing the asphalt and the modifier. Since the polyethylene wax is made of polyethylene as the base, it is preferable to use the polyethylene wax at a processing temperature of 100 to 120 degrees and a specific gravity of 0.89 to 0.92.
Meanwhile, the second mixing portion may be blended at 150 to 190 ° C and extruded using a single-screw extruder or a multi-screw extruder to produce a pellet.
When the first mixing portion and the second mixing portion are manufactured, they can be mixed. The first mixing portion is put into the second mixing portion and stirred at 70 to 120 ° C for 30 minutes to 2 hours to form an asphalt modifier Can be produced.
Hereinafter, one embodiment of the present invention will be described in detail.

How to measure
1. Heat resistance test (softening point)
Perform softening point (℃) test by KS M 2250 (ks standard reading site)
2. Tg (-25 C); Differential Scanning Calorimetry (DSC)
DSC is a method of measuring the energy absorbed or released by a sample while heating, cooling, or maintaining a constant temperature. Measured by ASTM D 3418 (temperature rise 10 / min, dropping temperature 10 / min) using DSC equipment (Q2000)
3. Dynamic Shear Stress
Dynamic shear rheometer (DSR) using KS F 2393 method.
4. Dissolution Time Experiment
The temperature of the plasticizer (ex DINP) was raised to 150 ° C using a hot-water stirrer. The ratio of the asphalt modifier to the plasticizer was measured at 1:20, and the dissolution time was measured.
The physical properties of the asphalt modifier were summarized in Table 1 below.
In Examples 1 to 4, the softening point is higher than the comparative example by 10 ° C or more, and when the softening point is low, there is a high possibility that the problem will occur. That is, the friction between the asphalt and the vehicle tire may cause breakage, breakage, and denting because the asphalt packed with the temperature rise in the summer is especially melted and the mechanical properties are weakened. The product of the present invention has a softening point close to 90 캜.
Also, Tg is referred to as the glass transition temperature, and most of the low Tg material is in the rubber phase. The lower the Tg, the higher the fluidity at low temperature.
The lower the Tg value, the more elastic properties at low temperatures. In the case of winter or cold fat, when the temperature falls below -25 ° C, the asphalt itself is too brittle (hardness is increased) As shown in FIG. At this time, even a small impact may cause breakage, which is a problem.
In addition, since a substance having low Tg has fluidity at a low temperature, elasticity is generated. In the embodiments of the present invention, the Tg is less than -25 DEG C and therefore, the low temperature fluidity is excellent, .
In addition, the dynamic transfer stresses show that the embodiments are superior to the comparative examples.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge of.
