Description
Technical Field
The invention belongs to a crop straw utilization technology, and relates to a preparation method of plant fiber mulching film paper.
Background
With the continuous development of agricultural production, the scale of plastic mulching films used in rural areas is larger and larger, and the agricultural mulching films are generally formed by blow molding of plastics such as polyvinyl chloride and the like and are very thin films. The agricultural mulching film is difficult to recover after being used, most of the agricultural mulching film is abandoned in farmlands, and the agricultural mulching film cannot be degraded for a long time, so that the environment is polluted. In addition, when the degradable plastic mulching film produced at present is used, a large amount of plastic particles enter soil, so that the soil structure can be damaged, and the agricultural production can be influenced in the long term.
Disclosure of Invention
The invention aims to provide natural-color mulching film paper which can replace plastic films on the current market and solve the problems of difficult degradation and environmental pollution of the plastic mulching films.
The technical scheme of the invention is as follows:
a preparation method of plant fiber mulching paper comprises the following steps:
1) adding ammonium sulfite into the processed grass raw material for cooking, wherein the use amount of the ammonium sulfite is 10-25% of the absolute dry raw material, and the liquid ratio is 1: 2.5-10, introducing steam for heating, raising the temperature to 185 ℃, and preserving the heat for 220 minutes;
2) mixing the straw pulp prepared by steaming and boiling with the commodity wood pulp in proportion: 65-85% of straw pulp and 15-35% of wood pulp, feeding the mixed pulp into a disc mill for milling, and simultaneously adding 2-10% of wet strength agent auxiliary agent to enhance wet strength;
3) feeding the ground pulp into a fan pump, adding 2-10% of AKD (alkyl ketene dimer) auxiliary agent before feeding to enhance the water resistance, and obtaining papermaking pulp;
4) and (4) feeding the papermaking slurry to a paper machine for papermaking to produce the mulching paper.
Quantifying the prepared paper mulching film: 30.0-100.0 g/m2(ii) a Transverse tensile index of 10-30N.m/g, longitudinal tensile index of 20-40N.m/g, transverse wet tensile index of 4-10N.m/g, longitudinal wet tensile index of 6-15N.m/g, transverse tear index of 4-12mN.m2Per g, longitudinal tear index 4-10mN.m2(ii)/g, burst index 1.5-5kPa.m2Per g, surface absorption 10-30g/m2
