Abstract
The invention discloses a kind of closed loop curved face type composite paper-plastic material and preparation method and application.The preparation method comprises the following specific steps that：Water-repelling agent is to spray treatment around recycling paper stack, then drying process；Modified plastics film and whole paper paper hot pressing overlay film, acupuncture micropunch processing；Tectorial paper band rotates winding in the case where die surface heats pressurized state, and pressurize cooling, is made closed loop curved face type composite paper-plastic material.The main body of the composite material is hollow annular structure, both ends perforate, and ring assembling structure main body is made of paper lamination, and paper internal void is sufficient filling with by thermoplastic.The present invention improves osmotic efficiency of the plastic melt inside paper, improves moistureproof and waterproof performance, reduces internal structural defects, improves mechanical property；It can be used as the products applications such as supplying drainage, decorative tile, button wallboard through veneer and cutting process.
Description
Technical field
The invention belongs to technical field of composite materials, more particularly, to a kind of closed loop curved face type composite paper-plastic material and
Its preparation method and application.
Background technology
It is mainly secondary paper pulp papermaking that current paper, which recycles,.Although using recycled fiber papermaking it is opposite using timber as
Forest, water, electric consumption and pollutant emission can be greatly reduced for the pulping and paper-making of raw material, but since paper type is numerous
More, fiber quality difference is big, and there are non-fibrous materials such as various fillers, ink, colloids in paper, to slurrying
The pulp quality of journey has negative effect, increases papermaking cost.Moreover, pulping and papermaking processes must be provided using substantial amounts of water
Source, corresponding wastewater treatment virtually improve the cost of paper production enterprise.
The production technology of wood plastic composite is used for reference, the composite paper-plastic material based on paper fiber can overcome above-mentioned completely
Deficiency, and the added value of product of composite paper-plastic material compares higher for paper, is worth with more business promotion.Answered with wood moulding
The preparation process of condensation material is similar, and the preparation of composite paper-plastic material is broadly divided into three big mode of extrusion, injection and hot pressing.Wherein
Recycling paper first must be ground into single fiber by the above two, and then various with coupling agent, compatilizer etc. auxiliary agents and plastics are total to
Mixed extrusion, or injection molding.Processing mode highly energy-consuming, the poor efficiency, and the paper fiber crushed can form dust pollution.
Paper fiber composite material is prepared using heat pressing process, maximumlly retains paper integration, can be to avoid to paper
The destruction of structure and paper fiber, improves the mechanical strength of composite material, prepares composite paper-plastic material while reducing energy consumption
A kind of trend.Patent US4111730 discloses a kind of preparation method of waste paperboard, and the waste paper of fragment shape is mixed with adhesive, so
It is compacted and cures under high temperature afterwards.To reach moisture-proof purpose, wax emulsion need to be sprayed before compacting.Martina et al. is proposed will be useless
Paper intersects lamination with polypropylene film, and then hot pressing obtains a kind of alternate lamination fibrous composite of waste paper/plastics.Although should
The comprehensive mechanical property of the paper fiber composite material of structure is excellent, but its most paper fiber is by plastic wraps, and
It is directly to be contacted with air, causes the composite material water absorption rate generally 15%, maximum is more than 25%.Paper fiber water suction is made moist
The interface bond strength of composite material is reduced afterwards, thus mechanical strength reduces, and the microorganisms such as bacterium are easily grown, shorten paper fiber
The service life of composite material, application range are restricted.Secondly, above-mentioned composite paper-plastic material is planar plate types material,
The composite paper-plastic material material of curved face type material, especially closed loop curved face type is had not been reported.
The content of the invention
The defects of the purpose of the invention is to overcome the prior art, there is provided a kind of closed loop curved face type composite paper-plastic material
Preparation method.This method efficiently solves the prior art by the hydrophobically modified to paper fiber, micropunch technique and heat pressing process
The problem of mechanical property caused by internal structural defects and the moisture-sensitive water suction of middle composite paper-plastic material reduces.
The closed loop curved face type composite paper-plastic material prepared another object of the present invention is to provide a kind of above method.This is multiple
The main body of condensation material is hollow annular structure, both ends perforate, and ring assembling structure main body is made of paper lamination, paper internal void quilt
Thermoplastic is sufficient filling with.
It is still another object of the present invention to provide the application of above-mentioned closed loop curved face type composite paper-plastic material.
Above-mentioned purpose of the present invention is achieved by the following technical programs：
A kind of preparation method of closed loop curved face type composite paper-plastic material, comprises the following specific steps that：
S1. with water-repelling agent to spray treatment around recycling paper stack, then drying process, obtains whole paper paper assembly；
