Abstract
The invention discloses a raw material mixing method used when an automobile thermal insulating layer is manufactured. The method at least includes the following steps that firstly, main materials are added; secondly, first-time stirring is performed; thirdly, small materials are added; fourthly, second-time stirring is performed. A thermal insulating layer backing material produced through the method has the advantages of being good in sound-insulating effect and thermal-insulating effect, low in VOC content and excellent in performance.
Description
Technical field:
The present invention relates to the making of automobile heat insulation layer, be specially the blending means of the making Raw of automobile heat insulation layer.
Background technology:
Automobile heat insulation layer is generally used in automobile front wall under-dash, is fixed together by velcro and carpet, plays sound insulation, sound-absorbing, heat insulation effect.In order to the over-all properties of lifting vehicle, content is low, NVH (noise, vibration and sound vibration roughness) superior performance, product weight light and the feature such as recoverable to require automobile front wall thermofin to possess VOC (volatile organic matter matter).
Summary of the invention:
In order to solve the problem existing for background technology, the present invention is by the following technical solutions:
The blending means of the making Raw of automobile heat insulation layer, at least comprises the following steps:
(1) major ingredient is added;
(2) once stir;
(3) small powder is added;
(4) secondary stirring,
Described major ingredient comprises: propylene oxide condenses, fire retardant, whipping agent, pigment, methylene dichloride; Described small powder comprises: suds-stabilizing agent, tolylene diisocyanate.
In above-mentioned steps (1), the order of addition of major ingredient is: propylene oxide condenses → fire retardant → water → whipping agent → pigment → methylene dichloride; In above-mentioned steps (3), the order of addition of small powder is: suds-stabilizing agent → tolylene diisocyanate.
Further, a described churning time is 3-5 minute.
Further, the described secondary stirring time is 0.5-1 minute.
Further, during described secondary stirring, stirrer speed setting is 2800r/min.
It is effective that the thermofin bed material that the present invention produces has sound-insulating and heat-insulating, and VOC content is low, the advantage of superior performance.
