Abstract

The utility model discloses a bamboo-wooden gummed compartment baseboard for passenger-carrying vehicles, being mainly made of raw materials of bamboo and wood. Being manufactures by the process of coating or sinking glue, lay-up, hot pressing, etc., the utility model is characterized in that a surface layer adopts a woody veneer, a sandwich layer adopts a bamboo screen, and a base layer adopts a bamboo mat or a woody veneer. The physical and mechanical properties of finished goods completely conforms to the prescribed technical requirements of trade standards of < < bamboo split plywood (LY/T1575-2000) used for the bottom plate of an automobile compartment > >. The utility model can not only directly meet the requirements for the physical and mechanical property and the appearance of platform floor of ordinary passenger vehicles but also pave plastic floor leathers or carpets on an upper surface of the platform floor according to the decorative requirements of high-grade passenger vehicles to improve the decorative effect. Therefore, the defects of easy relative slipping of the floor leather and the bottom plate, the work waste for assembly and the easy damage of the paved materials can be avoided.

Description

A kind of passenger car closes cabin floor with the bamboo wood glue

One, technical field

The utility model belongs to the wood-based plate manufacturing technology in the timber industry.

Two, background technology

The material that the passenger car cabin floor is commonly used is bamboo plywood, wood gluing plate, plastic molding board etc.Plastic molding board price height, and have shortcomings such as poor flexibility, human body tactile property be bad, now seldom adopt.Bamboo plywood has replaced the main flow material that the wood gluing plate becomes the passenger car cabin floor owing to mechanical property brilliance, good springiness.But the bamboo plywood surface material is generally hand-knitted bamboo mat or the softening bamboo chip that flattens, and appearance is attractive in appearance inadequately, and thermal insulation is also relatively poor.Common solution is to lay plastic floor leather or carpet to improve decorative effect at the upper surface of cabin floor.The main deficiency of this method is that flooring laminate separates with baseboard material, easily produces relative slippage, and not only assembling is taken a lot of work, and paver is fragile.

Three, summary of the invention

The purpose of this utility model is a kind of bamboo wood composite veneer structure of design, makes it sticking for whole with surperficial paver, and improve the plate surface evenness, the novel passenger car that reduces the sheet metal thickness deviation closes cabin floor with the bamboo wood glue.

Technical solution of the present utility model is: with Wooden veneer, bamboo curtain splint or Wooden veneer, bamboo curtain splint, bamboo mat is primary raw material, it is characterized in that surface layer (1) adopts Wooden veneer; Core material adopts bamboo curtain splint; Primer adopts bamboo mat or Wooden veneer.Through assembly, soak/gluing, drying, obtain passenger car cabin floor blank after hot-forming, on wide-belt sander, carry out thick surely sanding after being sawn into specification by the size of customer requirements, can obtain finished product passenger car cabin floor.The user can lay the assembling use behind the direct as required or bonding flooring laminate when making passenger vehicle.

Four, description of drawings

Fig. 1 is that surface layer, bamboo curtain splint are that sandwich layer, bamboo mat are the passenger car cabin floor structural representation of bottom for Wooden veneer, and surface layer among the figure (1) is a Wooden veneer, and (2) are vertical bamboo curtain splint, and (3) are horizontal bamboo curtain splint, and (4) are the bottom bamboo mat;

Fig. 2 is that surface layer, bamboo curtain splint are the passenger car cabin floor structural representation of sandwich layer and bottom surface for Wooden veneer, and surface layer among the figure (1) is a Wooden veneer, and (2) are vertical bamboo curtain splint, and (3) are horizontal bamboo curtain splint, and (4) are Wooden veneer.

Five, the specific embodiment

Embodiment one:

With bamboo curtain splint, bamboo mat, Wooden veneer is that raw material is made the passenger car cabin floor, its structure and manufacture method following (with reference to accompanying drawing 1):

Earlier bamboo is cutd open into thin bamboo strips used for weaving, be woven into bamboo mat and bamboo curtain splint respectively with thin bamboo strips used for weaving then.After bamboo mat and bamboo curtain splint are dried to water ratio≤8%,, be 20%～30% liquid phenolic resin adhesion agent dipping with solid content with multilayer bamboo curtain splint and one deck bamboo mat; Bamboo mat behind the impregnation and bamboo curtain splint are carried out ageing or low temperature drying.

To water ratio≤8%, single face is coated with the phenolic resin glue of solid content about 48% with wooden (poplar or pine) veneer drying, and glue-spread is controlled at 150～200g/m ²About; Ageing.

With the veneer is top layer (1), and bamboo curtain splint is sandwich layer (2), (3), and bamboo mat is that bottom (4) (with reference to accompanying drawing 1) carries out assembly.135～145 ℃ of temperature, carry out hot pressing under the condition of pressure 2.6～3.0MPa.

The half-finished product plate that is hot pressed into is sawn into the size that needs after stacking, cooling off, with wide-belt sander sanding is carried out on the veneer surface of top layer (1), and acquisition thickness of slab passenger car even, surfacing closes the cabin floor finished product with the bamboo wood glue.The physics of finished product, mechanical property meet the technical requirements of " automobile bodies base plate thin bamboo strips used for weaving veneer sheet (LY/T 1575-2000) " industry standard defined fully.

Embodiment two:

With bamboo curtain splint and Wooden veneer is that raw material is made the passenger car cabin floor, its structure and manufacture method following (with reference to accompanying drawing 2):

Earlier bamboo is cutd open into thin bamboo strips used for weaving, weave bamboo curtain splint with thin bamboo strips used for weaving then.After bamboo curtain splint is dried to water ratio≤8%, be 20%～30% liquid phenolic resin adhesion agent dipping with multilayer bamboo curtain splint solid content; Bamboo curtain splint behind the impregnation is carried out ageing or low temperature drying.

With the veneer is top layer (1) and bottom (4), and bamboo curtain splint is that assembly is carried out in sandwich layer (2) and (3).135～145 ℃ of temperature, carry out hot pressing under the condition of pressure 2.6～3.0MPa.

Use passenger car provided by the utility model to close cabin floor with the bamboo wood glue, not only can directly satisfy the requirement of day bus to physics, mechanical property and the outward appearance aspect of cabin floor, can also be according to the decoration needs of high-grade bus, lay plastic floor leather or carpet to improve decorative effect at the upper surface of cabin floor, avoided flooring laminate easily to produce relative slippage with base plate, assemble and take a lot of work and defective such as paver is fragile.

Claims

1. one kind is that the passenger car that raw material is made closes cabin floor with the bamboo wood glue with bamboo wood and timber mainly, it is characterized in that surface layer (1) adopts Wooden veneer, sandwich layer (2) and (3) employing bamboo curtain splint, bottom (4) to adopt bamboo mat or Wooden veneer.
