Background technology
Bamboo membrane, be attached to the film of vibration sounding during ﹑ flute on flute left end the 2nd hole, this film is taken from the stem of bamboo or reed, at ordinary times for keeping the fresh of film, can put into refrigerator cold-storage.Flute is different from a reason of vertical bamboo flute except holding by except difference, and be exactly that flute bamboo membrane can regulate sounding, vertical bamboo flute is then without film.This film is taken from the stem of bamboo or reed.Bamboo film is comparatively cheap, but easily breaks, and sound does not have reed film clear and melodious yet, so select reed film better.Should select rice white, more transparent film when choosing, general green grass or young crops or yellowing were tender, excessively old performances.The collection of bamboo membrane, can only in first 4 ~ 5 days of the annual lunar calendar " Grain Full " by time limitation, and early bamboo membrane is too tender, poor toughness; Evening, bamboo membrane was excessively old, and tone color is secondary.The first step, takes out the reed adopted back, disconnects by reed section; Second step, cutting reed one end with cutter becomes hollow tubular; Cut the other end of reed again; 3rd step, gets film; 4th step: remove film clothing; 5th step, arrangement and preservation; The extraction complex operation of visible bamboo membrane, cannot industrial applications.
Summary of the invention
The technical problem to be solved in the present invention be existing bamboo membrane extract the restriction being subject to time and individual human otherness cannot suitability for industrialized production, a kind of making method of artificial bamboo membrane is provided for this reason.
Technical scheme of the present invention is: a kind of making method of artificial bamboo membrane, it comprises the following steps: (1), with the paraffin high speed homogenization 5-10min of parts by weight by the bamboo juice of the Folium Bambosae flavone of 13-31 part, 6-12 part, the sodium lauryl sulfonate of 0.3-2.4 part and 5-17 part, then the deionized water adding 100-120 part wherein heats 1-3h at 100-120 DEG C; (2) Tyox B of the polypropylene and 0.05-0.4 part that add 4-7 part with parts by weight in mixing solutions stirs, and is cooled to room temperature and becomes Preblend; (3), by Preblend put into tablets press extruding pelletization, control prilling temperature is 120-200 DEG C; (4), by the particulate material feeding film-making machine through granulation obtain film, film is cut into suitable size and namely obtains artificial bamboo membrane.
The improvement of such scheme is the rosin spirit being also added with 0.4-1.2 weight part in described step (2).
The invention has the beneficial effects as follows that the making of artificial bamboo membrane is applicable to large-scale production and application, the artificial bamboo membrane obtained is substantially identical in toughness, tone color, transparency with the bamboo membrane taked from reed or bamboo in the past, and the impact not by external environment can be mass-produced; Add the anti-time that rosin spirit can improve artificial bamboo membrane, extend the work-ing life of artificial bamboo membrane.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1:(1), with the paraffin high speed homogenization 5min of parts by weight by the Folium Bambosae flavone of 13 parts, the bamboo juice of 6 parts, the sodium lauryl sulfonate of 0.3 part and 5 parts, then the deionized water adding 100 parts wherein heats 1h at 100 DEG C; (2) in mixing solutions, add the polypropylene of 4 parts with parts by weight and the Tyox B of 0.05 part stirs, be cooled to room temperature and become Preblend; (3), by Preblend put into tablets press extruding pelletization, controlling prilling temperature is 120 DEG C; (4), by the particulate material feeding film-making machine through granulation obtain film, film is cut into suitable size and namely obtains artificial bamboo membrane.
Embodiment 2:(1), with the paraffin high speed homogenization 10min of parts by weight by the Folium Bambosae flavone of 31 parts, the bamboo juice of 12 parts, the sodium lauryl sulfonate of 2.4 parts and 17 parts, then the deionized water adding 120 parts wherein heats 3h at 120 DEG C; (2) in mixing solutions, add the polypropylene of 7 parts with parts by weight and the Tyox B of 0.4 part stirs, be cooled to room temperature and become Preblend; (3), by Preblend put into tablets press extruding pelletization, controlling prilling temperature is 200 DEG C; (4), by the particulate material feeding film-making machine through granulation obtain film, film is cut into suitable size and namely obtains artificial bamboo membrane.
Embodiment 3:(1), with the paraffin high speed homogenization 7min of parts by weight by the Folium Bambosae flavone of 25 parts, the bamboo juice of 8 parts, the sodium lauryl sulfonate of 1.6 parts and 11 parts, then the deionized water adding 110 parts wherein heats 2h at 110 DEG C; (2) in mixing solutions, add the polypropylene of 5 parts with parts by weight and the Tyox B of 0.25 part stirs, be cooled to room temperature and become Preblend; (3), by Preblend put into tablets press extruding pelletization, controlling prilling temperature is 160 DEG C; (4), by the particulate material feeding film-making machine through granulation obtain film, film is cut into suitable size and namely obtains artificial bamboo membrane.
The artificial bamboo membrane obtained by embodiment 1-3 and the bamboo membrane naturally taked do performance comparison, and testing data is as follows:
Embodiment | Thermostability (min) | Transparency | Resistance to air loss (m/s.Pa) | Resistance to tearing (kN.m) |
Embodiment 1 | 3.1 | Transparent | 2.9 | 30 |
Embodiment 2 | 2.8 | Transparent | 2.8 | 32 |
Embodiment 3 | 2.9 | Transparent | 3.1 | 33 |
Nature bamboo membrane | 3.2 | Transparent | 2.7 | 28 |
Visible artificial bamboo membrane indices of the present invention has has all met or exceeded natural bamboo membrane.
As everyone knows, airtight preservation wanted by bamboo membrane, because natural bamboo membrane needs could preserve under the environment of a drying, proper temperature, otherwise easily aging, and embodiments of the invention 4 and embodiment 5 as follows:
Embodiment 4:(1), with the paraffin high speed homogenization 7min of parts by weight by the Folium Bambosae flavone of 25 parts, the bamboo juice of 8 parts, the sodium lauryl sulfonate of 1.6 parts and 11 parts, then the deionized water adding 110 parts wherein heats 2h at 110 DEG C; (2) in mixing solutions, add the polypropylene of 5 parts with parts by weight and the Tyox B of 0.25 part stirs, then be added with the rosin spirit of 0.4 weight part, be cooled to room temperature and become Preblend; (3), by Preblend put into tablets press extruding pelletization, controlling prilling temperature is 160 DEG C; (4), by the particulate material feeding film-making machine through granulation obtain film, film is cut into suitable size and namely obtains artificial bamboo membrane.
