Abstract

The invention relates to the technical field of modified treatment of willow weaving wickers, in particular to a nano chitin-aluminium oxide sol reinforced and modified pretreating agent for the willow weaving wickers and a preparation method thereof. The nano chitin-aluminium oxide sol reinforced and modified pretreating agent is composed of, by weight, 10-14 parts of aluminium oxide sol with the solid content being 20-25%, 0.1-0.2 part of nano chitin, 0.1-0.2 part of alkyl aryl sodium sulfonate, 0.01-0.02 part of sodium stearate, 6-8 parts of clear limewater, 0.1-0.2 part of polyoxyethylene and 40-50 parts of water. After the pretreating agent permeates into wicker fibers through high pressure, the compatibility is good after the nano chitin and the aluminium oxide sol permeate into the fibers; the clear limewater, the polyoxyethylene and the like have the functions of softening tissue, auxiliary bonding and the like, so that the efficient functions of strengthening, toughening and the like are achieved; the treated wickers are better in air permeability, and the surfaces of the treated wickers achieve dust prevention, smoothness, mould proofing and bacteriostasis; the service life of woven products is longer, the weight capacity is increased, and the serviceable range is further widened.

Description

A kind of nano chitin for wicker plaiting article wicker-alumina sol strengthens modification pretreating agent and preparation method thereof

Technical field

The present invention relates to wicker plaiting article wicker modification treatment technology field, be specifically related to a kind of nano chitin for wicker plaiting article wicker-alumina sol and strengthen modification pretreating agent and preparation method thereof.

Background technology

Wicker plaiting article is one of folks of china traditional handicraft product, people are just as common daily utility in ancient times, until after 20th century decades just rise gradually, the also project becoming selected areas of China foreign exchange earning gradually, Anhui Province has become one of three large wicker plaiting article production bases, the whole nation.

Wicker is as the material of wicker plaiting article, and it is by novel design, can be woven into that various honesty is natural, handsome in appearance, the practical art product of Portable durable.Along with industry development, product is constantly brought forth new ideas, and the willow having more Nover practical attractive in appearance is presented in face of client.But, because wicker is pure natural plant fiber, not humidity and drying, causes mechanical property to reduce, fracture of easily going mouldy, and bearing capacity is poor, govern further developing of product, if carry out pretreatment to wicker before establishment, improve the adaptability of its environment to external world, improve mechanical property, obtaining wicker plaiting article product quality like this will significantly be improved.

Summary of the invention

The object of the invention is to provide a kind of nano chitin for wicker plaiting article wicker-alumina sol to strengthen modification pretreating agent and preparation method thereof, in order to improve the serviceability of wicker, reach the object improving knitting quality, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of nano chitin for wicker plaiting article wicker-alumina sol strengthens modification pretreating agent, it is characterized in that, this inorganic agent is made up of the raw material of following weight portion: solid content is alumina sol 10-14, the nano chitin 0.1-0.2 of 20-25%, SAS 0.1-0.2, sodium stearate 0.01-0.02, clarification limewash 6-8, polyethylene glycol oxide 0.1-0.2, water 40-50.

Nano chitin-alumina sol for wicker plaiting article wicker strengthens a preparation method for modification pretreating agent, and it is characterized in that, the preparation method of this inorganic agent is:

(1) first SAS, sodium stearate are dropped in water, stir after material is dissolved completely, mixed solution is heated to 40-50 DEG C, then adds polyethylene glycol oxide, be uniformly mixed 30-40min, gained solution for standby;

(2) clarification limewash is dropwise added in alumina sol slowly, and constantly stir, add nano chitin after dropwising, ultrasonic agitation makes it be uniformly dispersed, subsequently the solution of gained mixed solution with step (1) gained is mixed completely, obtain wicker pretreating agent.

Pretreating agent advantage prepared by the present invention is: preparation method is simple for this pretreating agent, composition environment-protecting asepsis, there is good permeability, high pressure is utilized to be penetrated in wicker fiber during use, nano chitin wherein, it is good that alumina sol infiltrates through compatibility after in fiber, clarification limewash, the compositions such as polyethylene glycol oxide have softening tissue, the effects such as auxiliary adhesion, thus reach efficient enhancing, the effect such as toughness reinforcing, wicker gas permeability after process is better, surface is dust-proof smooth, fungus-resistant, the life of product be woven into is longer, bearing capacity increases, widen the scope of application further.

Detailed description of the invention

Embodiment

The pretreating agent of the present embodiment is obtained by the raw material of following weight portion (kilogram): solid content be 20% alumina sol 12, nano chitin 0.1, SAS 0.2, sodium stearate 0.02, clarification limewash 6, polyethylene glycol oxide 0.1, water 40.

The preparation method of the present embodiment inorganic agent is:

(1) first SAS, sodium stearate are dropped in water, stir after material is dissolved completely, mixed solution is heated to 40-50 DEG C, then adds polyethylene glycol oxide, be uniformly mixed 30min, gained solution for standby;

(2) clarification limewash is dropwise added in alumina sol slowly, and constantly stir, add nano chitin after dropwising, ultrasonic agitation makes it be uniformly dispersed, subsequently the solution of gained mixed solution with step (1) gained is mixed completely, obtain wicker pretreating agent.

The wicker crossed through this pre-treatment treatment comparatively with batch the compression strength of untreated wicker on average improve 38%, bending strength on average improves 35%, and the product bearing capacity be woven on average improves 48%, and in use more not easily mouldy damage, not easily binding dust.
