Description
Technical field
The present invention relates to the additive of composite, and in particular to a kind of polyvinyl-chloride foam material is special
With calcium base functional form filler and preparation method thereof.
Background technology
PVC wood plastic material belongs to environment-friendly products, and processing technology is highly developed, passes through mould and co-extrusion etc.
Mode can design shape and novel appearance product, and outward appearance with timber closely, have even
It is more more attractive than timber.The material is recyclable to be recycled, and is promoting resources circulation, energy-saving and emission-reduction, warp
Preferable economic benefit and social effect are brought in terms of Ji sustainable development.But existing PVC wood plastic
Material also exist excessive production cost pressure, the mechanical property of materials and weatherability is poor, corrosion-resistant,
The shortcomings of energy consumption is high, so as to limit its application field.China is a timber resources demand
Big country, but forest data deficiencies, have forbidden the denudation, and build with residential market to timber
Demand increasing year by year, to alleviate this contradiction highlighted, be inexorable trend to mould Dai Mu, newly
Type PVC wood plastic material is if reduction production cost, raising mechanical performance, improvement property will
It is addressed this contradiction.In current PVC foam system packing material using it is more be lightweight
Calcium carbonate or powdered whiting, and the addition of calcium carbonate is only capable of part reduces cost, can increase product
Weight, system viscosity increase, influence processing.Chinese invention such as Publication No. CN105001555A is special
Profit application disclose a kind of ageing-resistant PVC-M tubing of high-impact, the document discloses using PVC,
The raw materials such as precipitated calcium carbonate, MBS, calcium sulfate crystal whiskers, carbon black, by 2, the 6- tert-butyl groups to the third phenol
With the synergy of ethyl mercaptan, ageing-resistant PVC plastic material products are made, still, prepared by the technology
Process operation is complicated, and uses precipitated calcium carbonate and calcium carbonate crystal whisker, in the fabrication process, electricity
Stream is higher, and energy consumption is larger, and the reinforcement of calcium carbonate formation is irregular.Publication No. 102010552A
Chinese invention patent application disclose a kind of PVC/ calcium sulfate whiskers composite and its preparation side
Method, is combined using PVC and calcium sulfate whisker etc. and composite is made, add PVC intensity,
But the component used combines formed composite foaming irregularly, so as to be difficult in intensity
Requirements at the higher level are reached, and also there is poor toughness, processing temperature scope in the PVC material of prior art
It is narrow, the problem of corrosion resistance is not strong.Also someone is once attempted using natural anhydrite and lightweight carbonic acid
Calcium coordinates to prepare in the polychloroethylene pipes of higher intensity, such as Publication No. CN103740015A
A kind of high-strength polyvinyl chloride pipe of state's invention patent application publication, but the natural anhydrite with it is light
Matter calcium carbonate and acrylic resin foaming effect are poor, it is impossible to obtain the high intensity of smooth uniform in foaming
Section bar.

When DEG C oil bath removes the crystallization water in anhydrous gypsum part surface absorption water or entrainment dihydrate gypsum, control
Moisture 0.7%-0.8% processed.
Using the special calcium base functional form filler of polyvinyl-chloride foam material of the present invention, it can prepare
To lubrication and the more preferable facilitation that foamed in composite material, promote PVC even foamings,
Simultaneously can also effectively stability of composite materials temperature, be smoothed out chain reaction, course of reaction is not
Chain rupture, obtains more uniform product.
PVC is a kind of noncrystalline, polarity high molecular polymer, softening temperature and melting temperature compared with
Height, pure PVC must typically be processed in ability plasticization at 160-210 DEG C, and PVC strands contain chlorine
Atom, when temperature reaches 120 DEG C, pure PVC is to start de- HCl reactions occur, can cause PVC
Thermal degradation；Polyvinyl chloride resin is hard and crisp, poor fluidity, and viscosity is high, therefore must be added greatly in processing
The auxiliary agents such as stabilizer, lubricant, plasticizer, the toughener of amount are processed modification to PVC, this
On the one hand the addition of a little auxiliary agents can substantially increase the cost of material, and can destroy the one of PVC material
A little mechanical performances.The present invention mixes anhydrous gypsum with clay and inorganic reinforcer, at surface
Reason, applied to PVC foam material.A small amount of crystallization water in calcium sulfate, endothermic decomposition temperature is 160
DEG C or so, be conducive to PVC stable.Montmorillonite is the important inorganic filler of a class, with preferably tactile
Denaturation and plasticity, in expanded material can enhanced foaming when vacuolar membrane intensity and air-tightness；Talcum powder,
Wollastonite, mica and silica are good and small to the process equipment loss fillers of a class reinforcing effect.
In today of people's growing interest green product, in order to widen the application field of PVC material, reduce
To the poisonous and hazardous auxiliary agent of human body in PVC processing, material cost performance is improved, is the advantage of the present invention
