Abstract

The invention discloses a preparation method of a polylactic acid polyhydroxyalkanoate melt-blown non-woven material, and relates to the technical field of new non-woven materials. Polyhydroxyalkanoate and polylactic acid are added to be blended, the melt index of the melt-blown non-woven material is increased, meanwhile, the toughening effect of the melt-blown non-woven material is improved, under the condition that the tensile strength is not slightly changed, the toughness of the melt-blown non-woven material is improved, the elongation at break of the melt-blown non-woven material is improved, the melt-blown non-woven material has environment-friendly and biodegradable properties, and also has better mechanical properties, possibility is provided for subsequent development and wide application of the materials, the power driving end of a micro stepping motor is connected with a screw, the outer portion of the screw is in threaded connection with a lower cover plate and an upper cover plate from bottom to top, the screw is driven by the micro stepping motor to conduct forward and reverse transmission, the effect of raw material quantitative discharging can be achieved, and the dosage accuracy, use convenience and practicability are improved.

Description

technical field [0001] The invention relates to the technical field of new nonwoven materials, in particular to a method for preparing polylactic acid polyhydroxyalkanoate melt-blown nonwoven materials. Background technique [0002] Meltblown nonwoven technology is becoming an indispensable and important means of providing new fiber materials. It is a branch of the emerging material industry and is gradually being used in aerospace, environmental protection, agriculture, medical care and people's daily life. Non-woven new materials have also become an increasingly important product and are widely used in filter materials, oil-absorbing materials, sound insulation materials, medical and sanitary materials, industrial and household wiping materials, thermal insulation materials and other fields. With the rapid development of the modernization of various industrial sectors in our country, the country pays more and more attention to the treatment of three wastes and the preventi...
