In existing automobile industry, the cover plate of spare tire of automobile is typically punched into using the gluing composite carpet of hardboard
Type, PP（Polypropylene）Injection molding, PP cellular boards punching/pressing mold shaping, PP wood flour board（Containing hollow blowing method）Compression molding etc.
What material and production technology were made.Above-mentioned cover plate of spare tire of automobile has the following disadvantages, and weight is heavy, high temperature deformation is big, sound insulation
The defect such as noise reduction is bad, bearing capacity is limited.With automotive material technology development and automobile consumer's theory it is continuous
Change and ripe, existing cover plate of spare tire of automobile can not meet auto vendor and consumer to the durability of automobile, security, relax
Requirement in terms of adaptive, the feature of environmental protection and economy.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and there is provided a kind of load is big, sound insulation and noise reduction effect is good, matter
Amount is light, with the cover plate of spare tire of automobile that polyurethane composite plate is base material, to meet durable automobile industry, safety, light weight, relax
Suitable, environmental protection, the requirement of economy.
The technical scheme provided according to the utility model, it is a kind of with the automobile spare tire lid that polyurethane composite plate is base material
Plate, structure is as follows：Including nonwoven layer, bonding fiberglass layer, polyurethane PU layer and side precoat；The polyurethane PU layer is located at
Centre, is respectively equipped with one layer of bonding fiberglass layer, side precoat is provided with above the bonding fiberglass layer at top, the bottom of positioned at up and down
Provided with layer of non-woven fabric layer below the bonding fiberglass layer in portion.
The polyurethane PU layer material therefor is the PU of polyurethane cell structure.
The bonding fiberglass layer material therefor is that glass fibre passes through high temperature with polypropylene PP or high density polyethylene
High pressure and cool down compacting composition form.
The nonwoven layer material is polyethylene terephtalate.
The polyurethane composite plate grammes per square metre is 1500g/m2To 3500g/m2。
The side precoat material therefor is non-woven fabrics, fabric, chamois leather fabric or needle punched carpet.
The beneficial effects of the utility model：The utility model weight is very light, and sound insulation and noise reduction effect is good, polyurethane PU plate weight
Amount is light, load-carrying ability is big, and with high buffering high impact properties；Described PP fiberglass layers are thermoplastic composites, heated
The body shape of spare tire cover plate needed for being formed after molding, is easy to the cooperation and assembling of spare tire cover plate.
As an improvement, described binding agent is HDPE film or PP films, described HDPE film is that polythene material is made, institute
The PP films stated are that polypropylene material is made, after hot-forming, make to bond very firmly between product each several part, and environmental protection
Property is preferable.And do not need adhesive to combine between the base material and fabric, VOC emission is low, reduce in-car harmful substance
Discharge, low-carbon environment-friendly improves in-car environment by bus, meets the development trend of automobile industry.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals：1st, nonwoven layer；2nd, fiberglass layer is bonded；3rd, polyurethane PU layer；4th, side precoat.
Embodiment
As shown in Figure 1：It is a kind of with the cover plate of spare tire of automobile that polyurethane composite plate is base material, structure is as follows：Including nonwoven
Layer of cloth 1, bonding fiberglass layer 2, polyurethane PU layer 3 and side precoat 4；The polyurethane PU layer 3 is located at centre, sets respectively up and down
There is one layer of bonding fiberglass layer 2, the top of bonding fiberglass layer 2 positioned at top is provided with side precoat 4, the bonding glass positioned at bottom
The lower section of layer 2 is provided with layer of non-woven fabric layer 1.
Above each several part first nonwoven layer 1, bonding fiberglass layer 2, polyurethane PU 3 part heating and melting of layer and suppresses cooling
Shaping, the composite plate after shaping bonds with side precoat 4 by baking oven heating again and is molded into spare tire cover plate again.
As shown in figure 1, described nonwoven layer 1 typically uses PET fabric hot rolled nonwoven fabrics, it can be changed according to different requirements
For spunlace non-woven cloth, spun-bonded non-woven fabrics or needle punched non-woven fabrics.
As shown in figure 1, described bonding fiberglass layer 2 is a kind of thermoplastic composite, using glass fibre and PP glue
Powder or glued membrane mixing hot pressing, can also be glued together with nonwoven layer 1, polyurethane PU layer 3, side precoat 4, according to not simultaneously
Same bearing requirements, can freely adjust corresponding grammes per square metre, the grammes per square metre of general PP fiberglass layers can be 200-1000g/m2.According to
Different heat resistance requirements, can also be replaced with PP rubber powders or glued membrane HDPE rubber powder or glued membrane.
