Abstract
The utility model proposes light GMT spare tire cover plate, formed by five layers of mold pressing, ground floor is non-woven fabrics decorative layer, the second layer is bonding polypropylene watertight composition, third layer is light GMT enhancement layer, and the 4th layer is bonding polypropylene watertight composition, and layer 5 is water-fast non-woven fabrics overcoat.Described light GMT spare tire cover plate main body is combined by bonding watertight composition and GMT, has waterproof, high strength, simultaneously extremely low organic volatile, reaches the object of waterproof, enhancing, low emission.The utility model has following advantage: 1, light GMT is that glass fibre and polypropylene mold pressing form, and has very high strength and modulus; 2, utilize polypropylene glued membrane (Main Ingredients and Appearance PE, PP, EVA etc.) characteristic, heat fused is bonding, and the adhesive film formed after cooling curing can intercept again the immersion of water, is combined to form dual waterproof construction with light GMT; 3,5 layers once hot-forming, improve production efficiency, reduce manufacturing cost.
Description
Technical field
The utility model relates to a kind of cover plate of spare tire of automobile, especially light GMT spare tire cover plate.
Background technology
In recent years, auto industry is transferred to the transition and upgrade stage grown steadily by high speed development, and at the beginning of 2013, continuous wide range of haze weather, makes the whole society profoundly experience air-polluting seriousness, and people are concern for the environment and disposal of pollutants problem more.
Spare tire cover plate is for isolating spare tyre under passenger car boot carpet, provides the storage space that clean and tidy for going on a journey.Present cover plate of spare tire of automobile fiberboard used, wood interlayer plate material, the control difficulty of its water proofing property and organic volatile discharge is large, and manufacturing expense is high, is difficult to satisfied current laws and regulations requirement.
Summary of the invention
For solving organic volatile discharge and water proofing property, ensureing the intensity of cover plate of spare tire of automobile, the utility model proposes light GMT spare tire cover plate.
The technical solution of the utility model is: light GMT spare tire cover plate, it is characterized in that: spare tire cover plate is formed by five layers of mold pressing, ground floor is non-woven fabrics decorative layer, the second layer is bonding polypropylene watertight composition, third layer is light GMT enhancement layer, 4th layer is bonding polypropylene watertight composition, and layer 5 is water-fast non-woven fabrics overcoat.
Beneficial effect: described light GMT spare tire cover plate main body is combined by bonding watertight composition and GMT, has waterproof, high strength, simultaneously extremely low organic volatile, reaches the object of waterproof, enhancing, low emission.The utility model has following advantage: 1, light GMT is that glass fibre and polypropylene mold pressing form, its shaping rear internal structure is just as armored concrete, there is very high strength and modulus, 100 ㎏ deformation under load amounts of exerting pressure are less than 15 ㎜, load is removed rear deformation and is recovered voluntarily, and excellent load-carrying properties can meet various loading demand; 2, utilize polypropylene glued membrane (Main Ingredients and Appearance PE, PP, EVA etc.) characteristic, heat fused is bonding, and the adhesive film formed after cooling curing can intercept again the immersion of water, is combined to form dual waterproof construction with light GMT; 3,5 layers can be once hot-forming, decrease the production cycle, improve production efficiency, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model light GMT spare tire cover plate.
Detailed description of the invention
Light GMT spare tire cover plate as shown in Figure 1, be: non-woven fabrics decorative layer 1, bonding polypropylene watertight composition 2, light GMT enhancement layer 3, polypropylene gather bonding watertight composition 4, water-fast non-woven fabrics overcoat 5 that non-woven fabrics decorative layer 1, bonding polypropylene watertight composition 2, light GMT enhancement layer 3, polypropylene gather bonding watertight composition 4 and water-fast non-woven fabrics overcoat 5(1-5 layer from top to bottom) by heating and mould pressing aftershaping.
Shown in Fig. 1, the thickness of non-woven fabrics decorative layer 1 is 1-2 millimeter, the thickness of bonding polypropylene watertight composition 2 is 0.1-0.2 millimeter, the thickness of light GMT enhancement layer 3 is 4-6 millimeter, the thickness that polypropylene gathers bonding watertight composition 4 is 0.1-0.2 millimeter, and the thickness of water-fast non-woven fabrics overcoat 5 is 0.5-1 millimeter.
