Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is cross-sectional schematic of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
As shown in Figure 1 and Figure 2,1 is safety belt, and 2 is EVA protective sleeve, and 3 is the upper strata EVA sheet of well cutting shape, and 4 is lower floor's EVA sheet.During making, lower floor's EVA sheet 4 is placed in mould, then safety belt 1 is put into, then put into upper strata EVA sheet 3, make after cold pressing together after matched moulds compacting and cooling.
The present invention's pressing process process of colding pressing depends on application requirement, and fusion type can be divided into suppress, and separate type is suppressed.
Fusion type suppress: by control cold pressing compacting temperature and pressure upper strata EVA sheet 3 and lower floor's EVA sheet 4 are fitted tightly on safety belt 1, become integrated product, inseparable.
Separate type is suppressed: place heatproof isolated film or coating grease on the surface of safety belt 1, by compacting of colding pressing, upper strata EVA sheet 3 and lower floor's EVA sheet 4 can be pressed together and become EVA protective sleeve 2, can separate after depanning with safety belt 1.
Described temperature of colding pressing compacting is 125 ~ 135 DEG C, and pressure is 50 ~ 70KG/ square centimeter.
Described EVA protective sleeve (upper strata EVA sheet and lower floor's EVA sheet) is foamed by EVA material and makes; By weight, described EVA material is composed of the following components:
100 parts of EVA,
20 ~ 50 parts of fillers (calcium carbonate or talcum powder),
40 ~ 70 parts of blowing agents (AC-3000H),
0.5 ~ 0.6 part of bridging agent (DCP, TAIC or BIPB),
1 ~ 2 part of foamed promoter (zinc oxide),
0.5 part of lubricant (stearic acid),
3 ~ 5 parts of antistatic additive,
12 ~ 20 parts of fire retardants (magnesia),
1 part fast ripe dose (TAC),
1 ~ 20 part of colouring agent.
In described EVA material foaming process: blowing temperature is 150 ~ 170 DEG C, expansion rate is 90 ~ 110 seconds/mm, and pressure is 150kg/ square centimeter.
Described safety belt can be made up of leather, canvas, chemical fibre or polyamide fibre.
The parcel scope of EVA protective sleeve or length can adjust according to actual needs, such as overall parcel, local parcel, and point-like is wrapped up.
Bulk packaging type: for industrial safety band, can adopt fusion type to suppress, and by all safety belt regions parcel EVA protective sleeve, makes integral safety band, has both ensured intensity and the size of existing safety belt, increase comfort and human contact's security again.
Local packaging type: for car belt; fusion type can be adopted to suppress, add the scheme of local parcel, only on several points of safety belt and human contact, wrap up EVA protective sleeve; do not affect the proper motion of the Shen Juan mechanism of car belt, meet comfortableness and cost requirement simultaneously.
Independent interconnection system: for car belt, also can adopt separate type to suppress, then connect separately or be assembled on safety belt, can adopt the buckle of belt-like, or the method that nylon is bonding.Can on safety belt, reserve several hole or stick nylon butt strip in advance.After the upper-lower position of adjustment EVA protective sleeve, press buckle or glue nylon6 chips, allowing EVA protective sleeve rest on the position of comfortable laminating human body.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
