Abstract
The invention relates to a plate applied to internal decoration of a vehicle, in particular to a vehicle spare tire cover plate. The vehicle spare tire cover plate comprises a surface layer and a filling layer, wherein a cavity is formed in the surface layer and the cavity is filled with the filling layer. The vehicle spare tire cover plate is characterized in that the surface layer is made of unsaturated polyester resin, and the filling layer is made of polypropylene plastic foaming materials or rigid polyurethane. The invention additionally provides a method for manufacturing the vehicle spare tire cover plate. By means of the technical scheme, the heat-resistance performance of the product is improved, the product is prevented from deformation under the high temperature, and the weight of the product is prevented from being excessively large. The filling layer is used for further enhancing the strength of the product and additionally ensuring that the product is light in weight. Thus, the weight of the whole product can be effectively controlled.
Description
Technical field
The present invention relates to a kind of sheet material that is applied to automobile interior, relate in particular to a kind of vehicle spare tyre cover plate; The present invention provides a kind of preparation method of vehicle spare tyre cover plate simultaneously.
Background technology
Cover plate of spare tire of automobile product is arranged in car trunk, and for separating tyre-well and baggage container, play the effect of covering article in spare tyre, driver's tool and carrying baggage container, and apparent condition plays the effect of decorating baggage container.The material of existing spare tire cover plate is selected upper, adopts PP injection moulding more, PP bending block, but this material makes spare tire cover plate resistance to heat poor, and PP material sinter point is 90-95 ℃, under high temperature, strength character reduces, and can cause product generation deformation, affects product size; Also have and adopt PP wood flour board material, but the intensity of PP wood flour board material and Dent resistance are poor, easily cause the generation of fracture, Fragmentation Phenomena, and in order to improve its intensity, the product that adopts PP wood flour board hollow blowing method to make, although reached the intensity requiring, the weight of product is larger; In addition, adopt in addition hardboard, because it is solid construction, have equally the problem that weight is larger.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides the vehicle spare tyre cover plate of high, the lightweight and difficult generation deformation of a kind of intensity.
For achieving the above object, vehicle spare tyre cover plate of the present invention, comprises the inner skin covering of the surface that forms cavity, and is filled in the packed layer in cavity, described skin covering of the surface adopts unsaturated polyester resin to make, and described packed layer adopts acrylic plastering expanded material or hard polyaminoester to make.
By choosing of skin covering of the surface and packed layer structure and material, make skin covering of the surface can bear higher temperature, improved the resistance to heat of product, avoided product generation deformation under high temperature, avoid the weight of product excessive simultaneously, and packed layer is when further strengthening the intensity of product, guaranteed the lightweight of product, make the weight of whole product obtain actv. control.
As the restriction to aforesaid way, described skin covering of the surface thickness is 1-1.5mm.By by the restriction of skin covering of the surface thickness, make skin covering of the surface there is good ductility and manufacture toughness, can at high temperature keep good stability.
The present invention provides a kind of preparation method of vehicle spare tyre cover plate simultaneously, and the method comprises the steps:
Step 3, slaking moulding, packed layer material in cavity after foaming and intumescing, the moulding of vehicle spare tyre cover plate;
Step 4, die sinking pickup, opens hot-die mould, and the vehicle spare tyre cover plate of moulding is taken out.
By as above method, skin covering of the surface is placed in to hot-die mould, can the in the situation that of temperature constant, realize evenly solidifying of skin covering of the surface, improve its hardness, adopt and blow to moulding simultaneously, guaranteed the homogeneity of skin covering of the surface thickness, made the hardness of integral product balanced, further guaranteed in major ingredient process, the expansion effect of packed layer material and with the bond effect of skin covering of the surface, improved the intensity of integral product.
As the improvement to aforesaid way, the material feeding of described step 2 is carried out under vacuum condition in cavity.By the setting of vacuum condition, make packed layer material can be fast, be evenly distributed in inner chamber, guaranteed the Integral synchronous performance that packed layer material foaming expands, make final product there is good homogeneity hardness, simultaneously, under vacuum condition, moment before packed layer material is filled, skin covering of the surface produces certain amount of recovery, when this amount of recovery guarantees that packed layer material foaming expands, can improve the fusion amount of packed layer and skin covering of the surface, the bond effect of packed layer and skin covering of the surface is strengthened, effectively improve the bulk strength of product.
As the restriction to aforesaid way, the vacuum pressure in described cavity is-0.8MPa--1MPa that the dwell time is 3-5s.
As the restriction to the inventive method, in described step 1, to the air pressure of ventilating in die cavity, be 1.2MPa, duration of ventilation is 45-75s.
As the restriction to the inventive method, in step 2, described packed layer material is hard polyaminoester, and its A material is 100:50-60 with the weight proportion of B material.
As the restriction to the inventive method, in step 1, the mould temperature of hot-die mould is 180-200 ℃.
In sum, adopt technical scheme of the present invention, improved the resistance to heat of product, avoided product generation deformation under high temperature, avoid the weight of product excessive simultaneously, and packed layer is when further strengthening the intensity of product, guaranteed the lightweight of product, make the weight of whole product obtain actv. control.
