Description
Technical field
The invention belongs to high-tech functional composite material fields, and in particular to a kind of cheap, excellent, whiteness
Height, strong covering power, safe to use, adaptable high molecular polymer white master material and its preparation based on nano-aluminum hydroxide
Method.
Background technology
Whiteness (whiteness) is the degree for indicating substance superficial white, is indicated with the percentage of white amount.It surveys
The whiteness of earnest matter is usually using magnesia as standard white 100%, and it is standard reflectivity 100% to determine it.
White is light in all visible lights all while into visual range, and referred to as panchromatic light, is bright
Symbolic colour.What white represented be become clear, totally, freely, it is simple, graceful with it is chaste and undefiled.High molecular polymer needs female using white
Material.Other than because of a variety of causes such as decoration, hobby, protections, in process, by equipment, technique, operation, environment
The influence and restriction of equal various factors, usually can be due to excessively high temperature, or the contact with oxygen under high temperature environment, causes point
The variation of subchain section or functional group generates " xanthochromia ", seriously affects the quality of manufactured goods.In order to ensure and improve product matter
Amount technically, is usually also required to solve by adding white master material other than corresponding take measures.
In white master material, can play whitening effect mainly has high covering power, strong tinting strength, tinting power titanium dioxide (titanium dioxide
Titanium).Titanium dioxide is added in vector resin, the dispersion effect of titanium dioxide in the carrier is improved with part dispersant to make
, one of the main form as the application of world today's high molecular material auxiliary agent.
White master batch simple production process, easy to use, dispersion effect is excellent, is easy to implement production automation；It is wide at present
General to apply in courier bag, milk film, detergent bag, dentifrice tube, protective film, food pack and sheet material are molded, blow the products such as bottle
In.
Patent of invention：《A kind of PP spun-bonded non-woven fabrics white master material and its preparation process CN 102336949.B》、《White is poly-
Ester film CN 101367284.A》、《A kind of white master material special for coating film and preparation method thereof 101367969 A of CN》, all take off
It is titanium dioxide (titanium dioxide) to have shown the white pigment wherein used all.
But due to the price of titanium dioxide currently on the market constantly it is mad go up among, the price of overseas market is the same
Also high to go against accepted conventions, many material suppliers and white master material manufacturer increase the market competitiveness, take to reduce cost
Calcium carbonate, barium sulfate, the method for zinc sulphide etc., well beyond not influence product quality and performances are added among titanium dioxide
Rational use scope keeps price quite cheap, but product quality but declines to a great extent.Meanwhile the brightness reversion of titanium dioxide itself is asked
Topic is also stranded always and scratches users, currently, causing product since the quality of this white master material is unqualified there are many enterprise
Defect rate significantly rise, waste product increase significantly.
Patent of invention：《A kind of high flow flame-proof masterbatch and preparation method thereof 106566104 A of CN》With《It is a kind of fire-retardant
104893063 A of LDPE masterbatch and preparation method thereof CN》, all use aluminium hydroxide etc. and add as flame retarding function in masterbatch
Add agent.
