Abstract
The utility model discloses a polyurethane (PU) composite board for an automobile ceiling, which comprises a PU board. A first ethylene-propylene copolymer glue film layer, first glass fiber, a third ethylene-propylene copolymer glue film layer and a polyethylene (PE) glue film layer are sequentially compounded on one surface of the PU board, and a second ethylene-propylene copolymer glue film layer, second glass fiber, a fourth ethylene-propylene copolymer glue film layer and a non-woven fabric layer are sequentially composited on the other surface of the PU board. The polyurethane composite board adopts ethylene-propylene copolymer glue films to replace high-density polyethylene (HDPE) rubber powder in raw material during composition, and solves the problem of infirm bonding of the polyurethane composite board arising from a series of problems generated during powder raising process due to small particle size of the glue powder, so as to ensure the quality of the polyethylene composite board.
Description
Technical field
The utility model relates to a kind of Rigid foam polyurethane, relates in particular to a kind of Rigid foam polyurethane that automobile ceiling is used that is used for.
Background technology
Original automobile ceiling is used Rigid foam polyurethane; In use there is great risk in the HDPE rubber powder that plays rigidity and cementation in the raw material that its compound tense uses;, powder spreading too dry, static excessive etc. less than normal like rubber powder granule all can cause phenomenons such as the powder amount is inhomogeneous, accumulated powder; Thereby cause the Rigid foam polyurethane grammes per square metre inhomogeneous, serious then directly cause the not firm layering of bonding.
Summary of the invention
The utility model overcomes deficiency of the prior art, and a kind of steady quality is provided, and the firm automobile ceiling that bonds is used Rigid foam polyurethane.
The utility model is realized through following Rigid foam polyurethane is provided:
A kind of automobile ceiling is used Rigid foam polyurethane; Comprise the PU plate; Be compounded with the first ethylene-propylene copolymer adhesive film, first glass fibre, the triethylene-propylene copolymer adhesive film, PE adhesive film successively on a surface of described PU plate, be compounded with the second ethylene-propylene copolymer adhesive film, second glass fibre, the 4th ethylene-propylene copolymer adhesive film (8), nonwoven layer on another surface of said PU plate successively.
The grammes per square metre of the said first ethylene-propylene copolymer adhesive film (4), the triethylene-propylene copolymer adhesive film (2), the second ethylene-propylene copolymer adhesive film (6) and the 4th ethylene-propylene copolymer adhesive film (8) is 50g/m
2Or 70 g/m
2Its CV value≤7%.
Said nonwoven layer is a spunlace non-woven cloth.
Play the HDPE rubber powder of rigidity and cementation in the raw material of the utility model with the use of ethylene-propylene copolymer glued membrane replacement Rigid foam polyurethane compound tense; Solved unstable problem, thereby guaranteed the quality of Rigid foam polyurethane because the Rigid foam polyurethane that a series of problems that produce in the rubber powder granule powder spreading process less than normal cause bonds.
Description of drawings
Fig. 1 is the agent structure sketch map of the utility model.
Wherein: 1 is the PE adhesive film, and 2 is the triethylene-propylene copolymer adhesive film, and 3 is first glass layer; 4 is the first ethylene-propylene copolymer adhesive film; 5 is the PU plate, and 6 is the second ethylene-propylene copolymer adhesive film, and 7 is second glass layer; 8 is the 4th ethylene-propylene copolymer adhesive film, and 9 is nonwoven layer.
The specific embodiment
Referring to Fig. 1; The automobile ceiling that the utility model provides is used Rigid foam polyurethane; PU plate 5; Be compounded with the first ethylene-propylene copolymer adhesive film 4, first glass fibre 3, the triethylene-propylene copolymer adhesive film 2, PE adhesive film 1 on a surface of described PU plate 5 successively, be compounded with the second ethylene-propylene copolymer adhesive film 6, second glass fibre 7, the 4th ethylene-propylene copolymer adhesive film 8, nonwoven layer 9 on another surface of said PU plate successively; Said nonwoven layer 9 is a spunlace non-woven cloth; The grammes per square metre of the said first ethylene-propylene copolymer adhesive film 4, the triethylene-propylene copolymer adhesive film 2, the second ethylene-propylene copolymer adhesive film 6 and the 4th ethylene-propylene copolymer adhesive film 8 is 50g/m
2Or 70 g/m
2Its CV value≤7%.
Claims (4)
1. an automobile ceiling is used Rigid foam polyurethane; It is characterized in that comprising PU plate (5); Be compounded with the first ethylene-propylene copolymer adhesive film (4), first glass fibre (3), the triethylene-propylene copolymer adhesive film (2), PE adhesive film (1) on a surface of described PU plate (5) successively, be compounded with the second ethylene-propylene copolymer adhesive film (6), second glass fibre (7), the 4th ethylene-propylene copolymer adhesive film (8), nonwoven layer (9) on another surface of said PU plate successively.
2. according to claims 1 described Rigid foam polyurethane, it is characterized in that the grammes per square metre of the said first ethylene-propylene copolymer adhesive film (4), the triethylene-propylene copolymer adhesive film (2), the second ethylene-propylene copolymer adhesive film (6) and the 4th ethylene-propylene copolymer adhesive film (8) is 50g/m
