Abstract
The invention belongs to the field of chemical processes, and provides a method for producing a semi-solidified hemp fiber felt. The method comprises the steps as follows: firstly, mixing chemical fibers with wood fibers to obtain a mixed raw material; secondly, sprinkling phenolic resin into the mixed raw material; thirdly, filling air current to enable the mixed raw material to form a net shape; and lastly, drying the mixed raw material, cutting into pieces and forming by hotly pressing. Natural plant fibers are used instead of the chemical fibers, so that the degrading process of waste parts is shortened; plant fiber hemp is mixed with the phenolic resin to form a felt, and the felt is semi-solidified at a low temperature, so that the semi-solidified felt is convenient to cut, transport and produce; and the produced semi-solidified hemp fiber felt has the advantages of high hardness, high bending strength, high temperature resistance, small deformation and facilitation of decomposition.
Description
Technical field
The invention belongs to the chemical technology field, relate in particular to a kind of method of producing the semi-solid preparation bast fibre felt.
Background technology
The semi-solid preparation felt that prior art provides is to use chemical fibre to add phenol-formaldehyde resin powder; Solidification point temperature heating forms through being no more than; Employed raw material can't solve the natural degradation problem, can only bury through combustion-type, and are comparatively serious to the pollution condition of environment.
Summary of the invention
The invention provides a kind of method of producing the semi-solid preparation bast fibre felt; The semi-solid preparation felt that being intended to solve prior art provides is to use chemical fibre to add phenol-formaldehyde resin powder; Solidification point temperature heating forms through being no more than; Employed raw material can't solve the natural degradation problem, can only bury through combustion-type, the problem comparatively serious to the pollution condition of environment.
The object of the present invention is to provide a kind of method of producing the semi-solid preparation bast fibre felt, said method comprising the steps of:
Chemical fibre is mixed with xylon, obtain mixed material;
In mixed material, spread phenolic resins;
Ventilation stream makes mixed material be netted;
Mixed material is dried, shear in flakes, and through hot-forming.
Further, said mixed material can be dried through drying baker.
Further, the bake out temperature of said mixed material is lower than solidification point.
The method of production semi-solid preparation bast fibre felt provided by the invention is at first mixed chemical fibre with xylon, obtain mixed material; In mixed material, spread phenolic resins, ventilation stream makes mixed material be netted then; At last mixed material is dried, shear in flakes, and through hot-forming; Use natural plant fibre instead of chemical fiber, shortened useless different degradation process, the string fiber crops are mixed into felt with phenol-formaldehyde resin powder; Reach the semi-solid preparation degree with low temperature, be convenient to cut, transport and produce, the semi-solid preparation bast fibre felt hardness of producing is big, bending intensity is big, high temperature resistant, distortion is little, be prone to decomposition.
Description of drawings
Fig. 1 shows the flow chart of the method for the production semi-solid preparation bast fibre felt that the embodiment of the invention provides.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further specified below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in the qualification invention.
Fig. 1 shows the realization flow of the method for the production semi-solid preparation bast fibre felt that the embodiment of the invention provides.
This method may further comprise the steps:
In step S101, chemical fibre is mixed with xylon, obtain mixed material;
In step S102, in mixed material, spread phenolic resins;
In step S103, ventilation stream makes mixed material be netted;
In step S104, mixed material is dried, shear in flakes, and through hot-forming.
In embodiments of the present invention, mixed material can be dried through drying baker.
In embodiments of the present invention, the bake out temperature of mixed material is lower than solidification point.
The method of the production semi-solid preparation bast fibre felt that the embodiment of the invention provides is at first mixed chemical fibre with xylon, obtain mixed material; In mixed material, spread phenolic resins, ventilation stream makes mixed material be netted then; At last mixed material is dried, shear in flakes, and through hot-forming; Use natural plant fibre instead of chemical fiber, shortened useless different degradation process, the string fiber crops are mixed into felt with phenol-formaldehyde resin powder; Reach the semi-solid preparation degree with low temperature, be convenient to cut, transport and produce, the semi-solid preparation bast fibre felt hardness of producing is big, bending intensity is big, high temperature resistant, distortion is little, be prone to decomposition.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
