Abstract
The invention relates to a new method for preparing a microcrystalline cellulose-enhanced acrylic acid wear-resistant coating by dispersing microcrystalline cellulose which is a natural renewable resource in acrylic resin. The used microcrystalline cellulose is the natural renewable resource which is green and environment-friendly; simultaneously, the coating has excellent wear resistance, gloss retention, color retention and outdoor aging performance, fast drying and convenient construction. The method opens up a new field of the application of the natural renewable cellulose resource, and the prepared wear-resistant coating is applicable to road marking paint, deck paint, floor paint and the like.
Description
Technical field
The invention belongs to paint field, relate to a kind of will being scattered in the acrylic resin, thereby the novel method of preparation microcrystalline cellulose-enhanced acrylic acid wear-resistant coating can be used for fields such as road marking paint, hard floor paint, porch paint from the Microcrystalline Cellulose of renewable resources.
Background technology
Wear-resistant paint is used very extensive as a kind of functional paint, it is coated on the surface of equipment, can significantly reduce the wearing and tearing of equipment, significantly improves economic benefit.
Acrylic resin paint has excellent photostabilization and outdoor aging performance.Generally can be divided into thermoplastic acrylic resin and thermosetting acrylic resin according to structure and membrane formation mechanism.Thermoplastic acrylic resin does not take place further crosslinked in film process, so its relative molecular weight is bigger, has good guarantor's light tint retention, water-fast chemical resistant properties, fast drying, easy construction, and recoat and doing over again is easy to construct.Thermoplastic acrylic resin is widely used in fields such as automobile, electrical equipment, machinery, buildings.
At present, thermoplastic acrylic resin is not used for the wear-resistant paint field because hardness is lower.Filler is an important component part of wear-resistant paint, by in thermoplastic acrylic resin, adding the high rigidity abrasive material, must (poly-4 monohydroxy butyric esters, Mierocrystalline cellulose) etc. as corundum, silicon carbide, quartz, boron nitride, inorganic crystal whisker (calcium sulfate, alkali magnesium sulfate, potassium titanate), organic crystalline, be expected to prepare and have the excellent photostabilization and the acrylic acid wear-resistant coating of outdoor aging performance.
Mierocrystalline cellulose extensively is present in nature, and the whole world can produce hundreds billion of tons of Mierocrystalline celluloses every year, is the incomparable reproducible great resource of oil.Microcrystalline Cellulose (Microcrystalline cellulose, MCC) be a kind of with β-1,4 glucoside bond bonded direct type polysaccharide, prepare through dilute acid hydrolysis to the limit polymerization degree by natural cellulose, be a kind of tasteless, imperceptible white corynebacterium particle, its granular size is generally at the 20-80 micron.Microcrystalline Cellulose mainly contains essential characteristic: the 1. mean polymerisation degree polymerization degree value that reaches capacity; 2. have cellulosic patterned features, degree of crystallinity is higher than the protofibril element; 3. have extremely strong water-absorbent, and in water medium, after powerful shearing action, have the gelatigenous ability of giving birth to.
Microcrystalline Cellulose has the characteristics of higher crystallinity, and higher physical strength can be provided.In recent years, be used as strongthener and use in nano reinforced composites, the matrix of use comprises polyvinyl chloride, polypropylene, polyoxyethylene etc., has all obtained good improved performance.And adopt Microcrystalline Cellulose that acrylic resin is strengthened and be used for being reported in of wear-resistant paint domestic also rarely have see.In addition, in coating, add Microcrystalline Cellulose, can also make coating have thixotropy, with the viscosity of control coating, mobile and brushing performance.
Summary of the invention
The objective of the invention is to Microcrystalline Cellulose is used for wear-resistant paint, improve the wear resistance of thermoplastic acrylic resin, a kind of novel method for preparing microcrystalline cellulose-enhanced acrylic acid wear-resistant coating is provided.
For achieving the above object, the preparation method that the present invention adopts is:
(1) preparation of acrylic matrix resin
With a certain amount of Acrylic Acid Monomer, initiator, solvent, in 82 ℃ thermostatically heating agitator, react.Behind the polymerization certain hour, the solids content of control resin, discharging.
Wherein, described Acrylic Acid Monomer is: methyl methacrylate (MMA), butyl acrylate (BA);
Described solvent is: dimethylbenzene; Described initiator is: peroxidation (two) benzoyl (BPO).
(2) Microcrystalline Cellulose and acrylic matrix resin blend
Take by weighing a certain amount of Microcrystalline Cellulose and join in an amount of organic solvent, then carry out the about 20min of ultrasonic dispersing, add a certain amount of acrylic matrix resin, behind the high-speed stirring certain hour, get sample.
Wherein, described solvent is: dimethylbenzene.
The invention has the advantages that:
1) Microcrystalline Cellulose that uses among the present invention is the natural reproducible material, environmental protection.
2) the prepared acrylic acid wear-resistant coating of the present invention has excellent abrasive (JM-4 type abrasion instrument is measured, Tianjin material experiment factory of smart section).
3) the prepared acrylic acid wear-resistant coating of the present invention has good guarantor's light tint retention.
4) the prepared acrylic acid wear-resistant coating of the present invention has excellent outdoor aging performance.
5) prepared acrylic acid wear-resistant coating fast drying, the easy construction of the present invention.
