Description
Technical field
The invention belongs to technical field of function materials, in particular to a kind of post-processing work that ultra-low formaldehyde melamine bubble is continuous
Skill.
Background technique
Melamine foam (melamine bubble is continuous) is a kind of percent opening prepared using melamine as primary raw material
The novel foamed plastic of up to 99.9% low-density three dimensional network structure, with excellent sound absorbing performance, flame retardant property, every
Hot property, insulating properties, hydrothermal stability, safety and sanitation and suitability for secondary processing etc..Melamine foam is in building, friendship
The fields such as logical, vehicle manufacture, acoustic engineering, electronic information and surface cleaning decontamination all have broad application prospects.
Since, using formaldehyde as made of raw material, free formaldehyde is volatile into air, to people's in melamine bubble silk floss
Eyes are damaged with the upper respiratory tract, seriously affect the health of people, therefore, how to remove remaining formaldehyde in de-bubble silk floss,
It is the key points and difficulties in the continuous production process of bubble.The existing mode for mostly using hot-air seasoning, requires heat to 250 DEG C or more,
Free formaldehyde in bubble silk floss is evaporated by heating, but there is a problem of drying impermeable, trip for larger-size melamine
It cannot be removed from formaldehyde.In short, the existing complex process for removing formaldehyde in de-bubble silk floss, higher cost, there is also exceeded for formaldehyde amount
Serious problem.
Summary of the invention
The present invention provides a kind of aftertreatment technology that ultra-low formaldehyde melamine bubble is continuous, and solution is existing, solves existing
The problem of going formaldehyde complex process, higher cost in de-bubble silk floss.
In order to solve the above technical problems, the technical solution of the present invention is as follows:
A kind of aftertreatment technology that ultra-low formaldehyde melamine bubble is continuous, includes the following steps:
(1) bubble silk floss is placed on the horizontal baffle of furnace body, air bells cap leads to 50~60 DEG C into furnace body on the roof of furnace body
The bottom of hot wind, furnace body is equipped with exhaust pipe；
(2) during leading to hot wind, the spray head at the top of furnace body sprays urea liquid to bubble is continuous；
(3) after the completion of spraying, the logical hot wind of stopping, draining 1~3 hour；
(4) open furnace body microwave device, microwave drying to get.
Wherein it is preferred to the bubble it is continuous with a thickness of 15~25mm.
Wherein it is preferred to which the horizontal baffle is the PPS plastic septum with mesh, the horizontal baffle quantity is more
It is a.
Wherein it is preferred to which the spacing of the adjacent horizontal baffle is 250~350mm.
Wherein it is preferred to which the mass percentage content of urea is 3~6% in the urea liquid.
Wherein it is preferred to the microwave device include on the roof and bottom wall for be arranged in furnace body microwave present mouth, described in connection
The microwave frequency that microwave presents mouth is 915MHz or 2450MHz.
Wherein it is preferred to which the microwave feedback mouth being arranged on roof and bottom wall is in staggered distribution.
Wherein it is preferred to the step of being additionally provided with microwave heating before leading to hot wind in the step (1).
Compared with prior art, the beneficial effects of the present invention are:
Method of the invention first opens microwave device, and microwave heating process makes to steep the temperature that continuous surface temperature is lower than continuous in-core
Degree accelerates the moisture in bubble silk floss from inside to outside and from surface evaporation, so that the migration for the formaldehyde molecule in bubble silk floss provides
Channel and driving force.It is then turned on air bells cap and leads to hot wind, make the further separate out of formaldehyde, be then turned on urea liquid spray dress
Set, removed after so that free formaldehyde is reacted with urea, be finally again turned on microwave device drying moisture, while also it is complete also at
The continuous maturing process of melamine bubble.
The present invention also completes bubble continuous ripe except aldehyde is high-efficient, reduces production cost except aldehyde while removing formaldehyde
Change process.
