Description
Technical field
The present invention relates to a kind of base material, and in particular to a kind of high polymer material base material and its preparation technology.
Background technology
High polymer material, also referred to as polymeric material, it is that i.e. polymer is the material of matrix composition with high-molecular compound
Material.Most of high polymer materials, in addition to solvent polymer, in order to obtain with various practical performances or improve its shaping
Processing characteristics, typically also various additives.Proportioning between the composition and composition of material fundamentally ensure that the property of product
Can, and various additives are then to optimize the performance of material to a certain extent
China is in the peak period of urbanization now, it is therefore desirable to carries out substantial amounts of architectural engineering, therefore needs a kind of economy badly
The construction substrate of environmental protection, but construction substrate now is if natural material then substantial appreciation of prices, and building base made of industry
Then there is the environmentally friendly risk of very big degree in material, while economy is not good enough yet, therefore develops a kind of use up for us and imitate
Fruit more preferably construction substrate.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide a kind of using effect more preferably, cost-effective and environmentally friendly
High polymer material base material.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of high polymer material base material, its innovative point
It is：It is made up of formula as below：Hydrated calcium silicate, calcium sulfate, polycarboxylate water-reducer, polyfluoroethylene resin, triethanolamine, hydroxyl second

Cellulose, ammonium carbonate and tetrabromobisphenol A carry out heat and melt, are stirred, and the mixing time is 1-3 hours；
（2）Extract stream slurry：After the completion of slurrying, within the effective time of gel, according to the difference of the thickness requirement of high polymer material,
Arrange appropriate stream slurry and press die chamber be conveyed into by the feed bin pipeline metering of press, pressure sizing is carried out after enough,
Even distribution during charging is paid attention to simultaneously；Preferably discharging opening is designed in equipment to reciprocate formula, and is equipped with cloth
Flattening device；Cloth follows the principle that a cloth once presses, can not stay material or lack material deficiency, so as not to waste of materials or
Press etc. is damaged, stream slurry amount is depending on the thickness of high polymer material and specification；
（3）Pressure sizing：After press cloth system completes appropriate charging, press drives compression system automatically, by following three times
Sequence progressive manner, pressure incrementally completion pressure sizing gradually, the pressure that presses first is unsuitable excessive, is suppressed by the density of slurry
Completing 50% is advisable；Second of course of exerting pressure is implemented in moment release after the pressurize several seconds, this time completes density compacting 90%；Pressurize again
Finally implement third time course of exerting pressure after several seconds, until maximum upper limit, release after pressurize in good time；
（4）Shaping and demoulding：After the completion of sizing, undetermined type semi-finished product after constant pressure maintenance certain time, start release in mold cavity
The demoulding, the speed of release must slowly be implemented, in order to avoid causing the fracture of sizing semi-finished product or secretly splitting, influence product quality, fixed
The good semi-finished product of the type time that constant pressure conserves in mold cavity must not be less than 5 seconds；Notice that press release speed is unsuitable too fast, every time
The time of release must not be less than 2 seconds；After the completion of the demoulding, the automatic residual slurry cleared up in mold cavity, it is ensured that dry in mold cavity
Only, the semi-finished product residual for occurring after pressure is prevented.
Beneficial effects of the present invention are as follows：Noninflammability A levels of the present invention, sheet material will not burn when fire occurs, and will not produce
Toxic smog；Electrical conductivity is low, is preferable insulating materials；In semi-outdoor and hot environment, the stabilization of retention property is remained to, no
It can sink or deform, in outdoor and high humility area, the wet rate that rises, contract with dry rate keep stable, waterproof, exhibit excellent moisture barrier properties.
