Abstract
Process for making soft felt of aluminium silicate fibre relates to the process of the soft felt of a kind of processing and manufacturing alumina silicate fibre heat-insulation and heat-preservation, comprises infiltration, die mould and oven dry three process.Promptly at first in the alumina silicate fibre surface spraying immerses through the interior binding agent of formulated or with alumina silicate fibre in the binding agent, to pack into through the alumina silicate fibre that soaks into then, extrusion forming is wet felt in the press-moulding die, and the heat insulation soft felt of preserving moisture of alumina silicate fibre is promptly made in the felt that will wet after demoulding oven dry.The soft felt of aluminium silicate fibre that adopts the present invention to make is not only well-pressed but also have toughness, is not scattered under the vibration or the situation of making moist or rupture, is particularly suitable for being used as automotive hood and inner trim panels.
Description
The present invention relates to a kind of process of processing and manufacturing soft felt of aluminium silicate fibre.
Alumina silicate fibre has the low and fire-retardant characteristics of thermal conductivity factor, be a kind of desirable heat-insulation and heat-preservation material and noise reduction acoustic material, but because alumina silicate fibre is a cotton-shaped staple fibre, thereby it is difficult with machine-shaping, the paper process that adopt are processed into fiberboard with alumina silicate fibre more in the prior art, or adopt needle point method that alumina silicate fibre is made tapetum fibrosum.No matter be fiberboard or tapetum fibrosum, its toughness is all very poor, be difficult for the curved surface that machine-shaping is more complicated, under the situation of vibrating and making moist, be easy to rupture or be scattered, thereby its scope of application is very limited, can only under static conditions, use, and can not be as automotive hood or automobile inside plaque etc.
The objective of the invention is to obtain a kind of process of processing and manufacturing soft felt of aluminium silicate fibre, make not only well-pressed but also flexible of prepared soft felt of aluminium silicate fibre, under the vibration or the situation of making moist, do not rupture or be scattered, not aging under heat baking situation, do not reduce heat preservation and insulation, but and machine-shaping be various complex-curved.
To achieve these goals, the present invention at first adopts a kind of interior binding agent through formulated to soak into alumina silicate fibre, to extrusion forming be wet felt in the alumina silicate fibre that interior binding agent soaks into is packed press-moulding die into then, the felt that will wet after demoulding oven dry promptly gets needed soft felt of aluminium silicate fibre.Be described in further detail below in conjunction with the technical characterictic of specific embodiment process for making soft felt of aluminium silicate fibre of the present invention.
Process for making soft felt of aluminium silicate fibre of the present invention mainly comprises infiltration, die mould and oven dry three process.Soaking into operation promptly is at a kind of interior binding agent through formulated of alumina silicate fibre surface spraying, perhaps alumina silicate fibre is immersed in the above-mentioned interior binding agent, and it is wetting that the alumina silicate fibre surface is able to.Pressure-type process promptly is that extrusion forming in the press-moulding die of packing into through the alumina silicate fibre of interior binding agent infiltration is wet felt, and extrusion forming can adopt simple and easy press to carry out.Baking operation promptly is that the wet felt after the demoulding is dried under 70～80 ℃ temperature conditions, and drying time is 24～48 hours, reaches 1.50～1.65g/cm with the soft felt unit weight after the oven dry
3Be as the criterion.
For the soft felt of alumina silicate that processing and manufacturing is gone out not only well-pressed but also flexible, aging under heat baking situation, do not reduce its heat preservation and insulation, the interior binding agent that is adopted in the infiltration operation of the present invention must pass through formulated, and its composition of raw materials is:
A, 100 parts of weights of water
B, concentration are 0.5～1.5 part of weight of poly-vinyl alcohol solution of 20%
C, horizontal number are 2.5～3.5 parts of weights of waterglass of 2.2～3
D, 4.5～5.5 parts of weights of latax
Its optimum feed stock prescription is:
A, 100 parts of weights of water
B, concentration are 1 part of weight of poly-vinyl alcohol solution of 20%
C, modulus are 3 parts of weights of waterglass of 2.2～3
D, 5 parts of weights of latax
Technology of the present invention is simple, prepared soft felt of aluminium silicate fibre is well-pressed but also flexible not only, does not rupture, is not scattered under the vibration or the situation of making moist, and is aging under heat baking situation, do not reduce its heat preservation and insulation, be particularly suitable for as automotive hood and automobile inner decoration sheet.
