Research & Development Development of Titanium Dioxide Nano-Powder

Development of Titanium Dioxide Nano-Powder

Developed by: Marjan Polymer Industries. Pakistan

Project In-charge: Dr. Muhammad Abid

Year: 2011

We, developed novel and simple method for preparing Titanium dioxide (TiO₂) Nano powder by using Sol Gel synthesis technique. The Structural, Thermal, Chemical, Morphological and Optical characterizations were carried out by XRD, DSC/TGA, FTIR, SEM and UV-visible Spectroscopy. The results showed that prepared powder was an amorphous in structure and transformed into anatase and rutile structures by annealing at 280^oC and 600^oC respectively. The grain sizes ranges from 7nm – 41nm and the Band gap was estimated 3.2 (eV).

Polyurethanes belongs to class of alternating segmented polymers which comprises mainly two alternative segments such as soft and hard segments. The Polyurethane dispersions were made by dispersing amphiphilic pre-polymers using soft segment (polyol), hard segment (diisocyanates), and internal emulsifier followed by chain extension steps.

Adopted Synthesis Process

The pre-polymer process. This technique is used to produce polyurethane coatings, elastomers and sealants.

2 OCN–R–NCO + HO ~~~~~~~~~ OH

(Oligo-diol)

OCN–R–NHCOO ~~~~~~~~~~ OCONH–R–NCO

(Pre-polymer)

This pre-polymer having free NCO terminals which further reacts with chain extenders and the resulting polymer (polyurethane) formed is a high molecular weight polyurethane.

OCONHRNHCOO ~~~~~~~~~~~~OCONHRNCO + HO–R¹–OH

(Pre-polymer) (Diol)

O–R¹–O [CONHRNHCOO ~~~~~~~~~~~ OCONHRNHCOO–R¹–O]n

(Polyurethane)

Results:

Transparent Coating
High Hardness
Excellent UV Protection
Excellent Impact Resistance
Excellent Chemical Resistance
High Gloss
Good Scratch Resistance
Good Rheological Flow
Excellent Colloidal Stability

What is Resin Infusion?

Resin infusion is a sophisticated technique for manufacturing high performance, void free composites even on large or complicated moulds. The process is ideally suited to the manufacture of carbon fibre composites and is widely used by professional manufacturers for the production of carbon fibre body panels such as bonnets and by marine manufacturers for the production of boat hulls, making this product ideal as a carbon fibre infusion kit. It is however, equally suited to the manufacture of smaller detailed items that would be all but impossible to make successfully using an open layup.

Reinforcement is laid into the mould ‘dry’, i.e. without any resin, and then enclosed in a specially configured stack of bagging materials (such as peel ply, infusion mesh and bagging film) before being subjected to vacuum pressure using a composites vacuum pump. Once all the air has been removed from the bag and the reinforcement has been fully compressed under atmospheric pressure, liquid epoxy resin (mixed with hardener) is introduced to the reinforcement through a pipe which then infuses through the reinforcement under the vacuum. Once the resin has fully infused through the reinforcement, the supply of resin is cut off (using a pipe clamp) and the resin is left to cure, still under vacuum.

In common with all Marjan Polymer Industries starter kits, our Resin Infusion Complete Starter Kit is the result of years of practical experience working with these materials, equipment and processes every day. Many of the connectors and pieces of equipment included in the kit are manufactured by us.
