Description
Technical field
The present invention relates to paint field, be specifically related to a kind of starch-based coating and preparation method thereof.
Background technology
The motion such as football, hockey lawn mainly contains natural grass and pedaline two class, natural lawn is expensive, maintenance cost is high, and at present only for high-end sports field and race, pedaline is widely adopted because having the plurality of advantages such as economy, round-the-clock property, non-maintaining property, wearing quality.According to laws of the game requirement, motion lawn generally all needs white functional line to carry out Site Design, natural lawn generally adopts lime powder to delimit functional line, easy construction, but functional line is outstanding not, and at functional line place, lime powder easily flies upward, contaminate environment, also can affect athletic healthy after suction; Chinampa generally adopts white turf as functional line, needs to cut turf, the comparatively complicated process such as bonding, not only increases construction cost, and leaves hidden danger, as safeguard not good cause come unglued.In addition, white functional line is once bonding construction completes, and the specification in place will be limited completely, is difficult to the design for change carrying out place specification, is difficult to the rich and varied property meeting mode of motion, also causes the waste of resource.
In recent years, coating industry fast development, coating motion functional line field, lawn application also gradually by lawn producer and client pay attention to.But, traditional cold coating due to the sticking power of artificial grass filaments PE is low and hardness is higher, not environmentally etc. defect cause it to apply being restricted always.
Summary of the invention
The object of the present invention is to provide a kind of asepsis environment-protecting, degradable, under water-less environment, continue attachment starch-based coating of long duration, the present invention also provides the preparation technology of this coating.
For solving the problem, the technical solution adopted in the present invention is as follows:
A kind of starch-based coating, its raw materials comprises the following component according to parts by weight: starch 10-50 part, water 30-75 part, white pigment 0.1-5 part, film coalescence aid 0.1-3 part, mould inhibitor 0.01-2 part and softening agent 0.1-10 part.
In the present invention, white pigment can be organic white pigment, also can be inorganic white pigment, one or more the combination that to be described white pigment be in titanium dioxide, nano-calcium carbonate, lithopone, zinc oxide of preferred scheme.
In the present invention, the preferred scheme at least one that to be described film coalescence aid be in polyoxyethylene glycol, polyvinyl alcohol, polyvinylpyrrolidone and polyacrylamide, modified-cellulose, alcohol ethers film coalescence aid, alkoxide film coalescence aid.
In the present invention, preferred scheme is the weight-average molecular weight of described polyoxyethylene glycol is 200-8000.
