The protection block is provided with an external rubber block and a bottom rubber block, wherein the elastic modulus of the bottom rubber block is more than that of the external rubber block; the two rubber blocks are superposed; the external rubber block mainly comprises the following raw materials: butadiene rubbers, natural rubbers, zinc oxide, stearic acid, vaseline, pine tar oil, sulfur and the like; and the bottom rubber block comprises the following raw material: polyurethaneWHT-1570IO. The manufacturing process comprises the steps of external rubber block processing, bottom rubber block processing and integral forming. The protection block and the manufacturing process have the following beneficial effects: the external rubber block and the bottom rubber block are respectively manufactured from two materials with different hardness; and the protection block can absorb the impact energy and buffer and resist strong impact and can inhibit resonance surge through interaction of the two rubber blocks, thus having good comprehensive collision defence effect.
Description
Technical field
The present invention relates to automobile safety anti-collision technique field, particularly belong to a kind of protection block of motor vehicle and manufacture craft thereof.
Technical background
The anticollision of motor vehicles product using in the market, its Practical Performance is not fully up to expectations.General traditional Federal bumper or improved type bumper/spoiler, anticollision effect is unsatisfactory, is more to play decoration function.Trace it to its cause, be mainly that metal bumper weight is large, if adopted, certainly will increase vehicle body deadweight, then bring the increase of oil consumption, thus most producer as far as possible need not, or select the bumper/spoiler of small dimension, light material.In addition, because metal bumper rigidity is large, while running into collision, buffering effect is poor, the extension of the loss that causes the accident thus.
Summary of the invention
Object of the present invention is to provide a kind of novel protection block of motor vehicle and manufacture craft thereof, to reach the object that quality is light, anticollision is effective.
Protection block of motor vehicle disclosed in this invention, has outer blob of viscose and primer piece, it is characterized in that, the modulus of elasticity of primer piece is greater than the modulus of elasticity of outer blob of viscose, and both are superimposed together; Wherein, the raw material ratio of outer blob of viscose (by weight) is: butadiene rubber, 60 parts; Natural rubber, 40 parts; Zinc oxide, 3 parts; Stearic acid, 0.5 part; Antioxidant 4010NA, 1.2 parts; Antioxidant H, 0.8 part; Petroleum ointment, 4 parts; Accelerant NOBS, 0.9 part; 660,9 parts of carbon blacks; Pine tar, 15 parts; Sulphur, 1.6 parts; The raw MAT'L of primer piece is: polyurethane WHT-1570IO.
The manufacture craft of protection block of motor vehicle disclosed in this invention, is characterized in that, comprises the steps:
1) outer blob of viscose processing;
Step 1-1, plasticates: two roller mill roll spacings are adjusted to 1 millimeter, and start idle running 5～10 minutes, then adds butadiene rubber and natural rubber to mould white silk, plasticates 8～10 times;
Step 1-2, mixing: the butadiene rubber through over-mastication is dropped into Banbury mixer hopper together with natural rubber, by raw material ratio, add successively zinc oxide, stearic acid, accelerant NOBS, antioxidant 4010NA, antioxidant H, carbon black 660, pine tar, sulphur, petroleum ointment, carry out banburying, after 5 minutes, take out;
Step 1-3, thin-pass: the sizing material through mixing is carried out to thin-pass with two roller mills, and roll spacing is adjusted to 0.5 millimeter, thin-pass 5～6 times, then roll spacing is adjusted to 5 millimeters, lower is stand-by;
Step 1-4, Mold Making: according to outer blob of viscose shape and size, make corresponding mould;
Step 1-5, outer blob of viscose is made: use vulcanizing press, preheated mold, temperature is 150～180 ℃, adjustment sulfide stress is 10～12MPa, adds outer blob of viscose film, matched moulds, presulfurization moulding 12 minutes, delivery, cleaning overlap, parks stand-by;
2) primer piece processing:
Step 2-1, according to the block-shaped making mould of primer, is arranged on injection machine;
Step 2-2, start preheating, it is 160～180 ℃ that injector head temperature is set, and adds polyurethane WHT-1570IO, starts injecting program, injection moulding;
Step 2-3, delivery, cooling, place stand-by;
3) global formation:
Step 3-1, by outer blob of viscose and primer piece corresponding surface brushwork adhesive, is then overlapped into both assembly to be integrated.
Protection block of motor vehicle disclosed in this invention and manufacture craft thereof, utilize two kinds of different materials of hardness to make respectively outer blob of viscose and primer piece, outer blob of viscose modulus of elasticity is little, hardness is low, when vehicle generation External Force Acting, energy-absorbing effect is relatively good, particularly can effectively alleviate extent of injury during vehicle generation slight impact; Primer piece hardness is higher, and modulus of elasticity is large, and rebound degree is high, shock-resistant, when Vehicular impact force rate is larger, can produce high resiliency, and moment changes crash direction.Therefore, the present invention, can absorbing impact energy when strong shock occurs vehicle, and Impact energy is changed into heat energy, can cushion and resist again powerful impact, and both interactions can suppress resonance and increase sharply, thereby reach good integrated campaign collision effect.
Accompanying drawing explanation
Accompanying drawing partly discloses specific embodiments of the invention, wherein,
1, protection block of motor vehicle front elevation;
2, protection block of motor vehicle birds-eye view;
3, A-A is to view;
4, B-B is to view.
The specific embodiment
As shown in Figure 1 and Figure 2, protection block of motor vehicle disclosed in this invention, consists of outer blob of viscose 1 and primer piece 2, and both are superimposed together.The two ends of primer piece 2 have is convenient to the hole slot 3 installed, can be directly and the position connection such as vehicle beam, longeron, chassis, vehicle body, can effectively alleviate the impact from different directions, thus the safety performance of raising automobile.
As shown in Figure 3, Figure 4, outer blob of viscose 1 and primer piece 2 both superimposed be by lay respectively at connecting pin 4 on primer piece and outer blob of viscose and with it corresponding connecting bore coordinate and realize.That is, the connecting bore on the connecting pin on primer piece and outer blob of viscose coordinates, or the connecting bore on the connecting pin on outer blob of viscose and primer piece coordinates, and its effect is all the same.For avoid superimposed rear gapped or install not firm, brushing one deck adhesion agent on the outside face of the corresponding surface of blob of viscose and primer piece and connecting pin and primer piece outside, as: Strong Adhesive FX-1103 or Kai Muluoke 250 adhesivess that Handan Xin Li Chemical Co., Ltd. produces.
