It is small, processing temperature range is wide, product colour is stable, product substance is lighter, cost is lower, after toughening modifying more suitable for low temperature ring
Border has compared to the higher Vicat softening point of PVC, can be applied to electrical product field such as socket, power pack, switch back seat
Deng, and it is able to satisfy all standard requirement of electrician's application field completely.
Preferably, the acrylic resin be homopolypropylene resin and acrylic resin reclaimed materials in mass ratio (1~
3): the compound of 1 composition, the melt flow index of homopolypropylene resin and acrylic resin reclaimed materials be (5~15g)/
10min.The application selects homopolypropylene resin and acrylic resin reclaimed materials compounding that stock utilization can be improved, and is conducive to provide
Source recycles, and reduces cost.
Preferably, the conventional flame retardants are phosphorus nitrogen bromine compound system fire retardant.It is resistance that the present invention, which is selected with phosphorus, nitrogen, bromine,
Fire the phosphorus nitrogen bromine compound system fire retardant of element, have additive amount it is low, without be precipitated, the characteristics such as water-fast, nontoxic.
Preferably, the inorganic enhanced fire retardant is answering for inorganic enhanced fire retardant 1 and inorganic enhanced fire retardant 2
With object, the inorganic enhanced fire retardant 1 is at least one of barium sulfate, montmorillonite, talcum powder；The inorganic enhanced resistance
Firing agent 2 is at least one of chopped glass fiber, roving glass fiber, glass powder, glass microballoon.It is found through experiment that the application selects addition
Different types of inorganic enhanced fire retardant will lead to the flame retardant properties, mechanical properties of polypropylene flameretardant material, shrinking percentage and
Vicat softening point changes.It is highly preferred that the inorganic enhanced fire retardant is the compound of barium sulfate and chopped glass fiber, and
The mass ratio of barium sulfate and chopped glass fiber is (1.5-2.0): when 1, the polypropylene flameretardant material being prepared has excellent flame retardant
Property, while possessing higher mechanical property and Vicat softening point.
Preferably, the toughener is at least one of POE, PP-MAN, EMA, promotes the toughening effect of material.
Preferably, the antioxidant is the mixture of hindered phenol antioxygen and phosphite antioxidant.
Preferably, the weight ratio of hindered phenol antioxygen and phosphite antioxidant is 1:(1.0-2.0 in the antioxidant),
Preferably 1:1, antioxygen property is good, and the polypropylene flameretardant material being prepared has both higher mechanical property and Vicat softening point.
Preferably, the lubricant is N, N'- ethylene bis stearamide, pentaerythritol stearate, single octadecanoid acid third
At least one of three alcohol esters.
The present invention also provides the preparation methods of the above-mentioned polypropylene flameretardant material that can be used for concealed bottom box production, including
Following steps:
(1) each component raw material is weighed in proportion, and each component raw material is put into high-speed mixer and is mixed；
(2) material of mixing is put into extruder, squeezes out, is granulated by frit reaction, obtains the polypropylene fire retardant
Material.
Preferably, in the step (2), the extrusion is squeezed out in double screw extruder, fabrication process condition are as follows: one
170-180 DEG C of area's temperature, two 175-185 DEG C of area's temperature, three 180-190 DEG C of area's temperature, four 180-190 DEG C of area's temperature, five Qu Wen
180-190 DEG C, 180-200 DEG C of head temperature, 300-450 revs/min of engine speed of degree.
Compared with prior art, the invention has the benefit that

Table 3
From the polypropylene flameretardant material and comparative example (PVC) mixed ingredients of embodiment 1-12, in figure 5 it can be seen that
1, the anti-flammability of polypropylene flameretardant material, oxygen index (OI) ratio PVC is higher, and self-extinguishing time ratio PVC is shorter, illustrates anti-flammability
It is more more excellent than PVC material.
2, the density of polypropylene flameretardant material is obviously lower than PVC mixed ingredients, it is meant that product substance is substantially reduced, total feed consumption
In constant situation, total output is obviously increased, and cost is lower.
3, the notch impact strength of polypropylene flameretardant material and fall-down test effect are better than PVC mixed ingredients, illustrate polypropylene
Fire proofing toughness is significantly stronger than PVC mixed ingredients, is more suitable for may cause the application environment of deformation of products, and be more suitable for low
Warm environment.Present invention addition barium sulfate and short glass fiber, the polypropylene flameretardant material being prepared mechanical property with higher, and
The mass ratio of barium sulfate and chopped glass fiber is (1.5-2.0): when 1, the polypropylene flameretardant material being prepared has excellent flame retardant
Property, while possessing higher mechanical property and Vicat softening point.
4, the shrinking percentage of polypropylene flameretardant material is similar to PVC mixed ingredients consistent, avoids in the production of concealed bottom box
Modification to original PVC injection mold.
5, the high temperature ageing experiment of polypropylene flameretardant material improves obvious than PVC mixed ingredients, and the product typed it out is not variable
Color.
6, the Vicat softening point ratio PVC mixed ingredients of polypropylene flameretardant material increase obvious, illustrate that polypropylene flameretardant material is infused
Molding concealed bottom box is moulded more tolerant to high temperature, is not easy softening transform.
7, for polypropylene flameretardant material by modified, oxidation induction period (OIT) generally all meets or exceeds common PVC material
Matter, but can see from test result, the ratio of hindered phenol antioxygen and phosphite antioxidant is most important, when ratio reaches
To 1:(1.0-2.0), effect is best when especially 1:1.
In the present invention, to improve stock utilization, cost is reduced, can be selected by homopolypropylene resin and acrylic resin
Reclaimed materials (1~3) in mass ratio: the acrylic resin of 1 composition, the melt of homopolypropylene resin and acrylic resin reclaimed materials
Flow index is (5~15g)/10min.
In the present invention, according to actual performance need can appropriate adjustment material composition and ratio, the polypropylene flameretardant material packet
Include the component of following parts by weight: 60-100 parts of acrylic resin, 2-5 parts of conventional flame retardants, inorganic enhanced fire retardant 20-40
Part, 2-5 parts of toughener, 0.2-0.6 parts of antioxidant and 0.5-1.0 parts of lubricant.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than protects to the present invention
The limitation of range is protected, although the invention is described in detail with reference to the preferred embodiments, those skilled in the art should
Understand, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the essence of technical solution of the present invention
And range.
