Abstract
The invention relates to a PBT (poly(butylene terephthalate))/GF (glass fiber)/bamboo charcoal composite material capable of releasing negative ions, which is characterized by comprising the following components: 50-80% of a resin, 0.1-12% of an Anion1050-series negative ion additive, 15-35% of reinforcing fibers, 1-7% of a coupling agent and 1.5-25% of an auxiliary agent, wherein the Anion1050-series negative ion additive is nano-scale ultrafine micropowder prepared from bamboo charcoal. The preparation process of the PBT/GF/bamboo charcoal composite material comprises the following steps of: mixing the coupling agent and the negative ion additive, and carrying out reaction for 3-4 hours while controlling the temperature at about 90 DEG C to carry out surface modification of the negative ion additive; uniformly mixing functional fiber, auxiliary agent and the resin according to a certain ratio, adding the surface-modified negative ion additive, and extruding and granulating with a unidirectional double screw machine to obtain a blended granular material; drying the blended granular material in a blast oven at 120 DEG C, wherein the material layer thickness is smaller than 2.5 cm; and injection-molding at the temperature of 230-250 DEG C to obtain a standard specimen. The amount of the negative ions released by the PBT/GF/bamboo charcoal composite material prepared by the preparation process is more than 1500 ions/cm<3>, thus reaching the fundamental need of material performance and health maintenance.
Description
Technical field
The invention belongs to Materials science, daily-use chemical industry, fine chemistry industry, preparation technology field.
Background technology
Polybutylene terephthalate is called for short PBT, is a kind of thermoplastic polyester class engineering plastics, and its high comprehensive performance has excellent machinery, electric property, resistance to chemical attack, easy-formation and agent of low hygroscopicity etc.In PBT, add after the glass fibre of 25%-35%, not only kept the advantages such as chemical resistant properties, processibility of PBT, and mechanical property increases substantially, and overcome the low deficiency of notched Izod impact strength of PBT, creep resistant, resistance to fatigue is good.Present PBT more than 80% is through using after the modification, at automobile, in the electric and daily life to widespread use.
The effect of bamboo charcoal
One. rich in mineral substances (trace element)
Bamboo wood is grown up in natural surroundings, water-soluble mineral substance such as a large amount of potassium, sodium, calcium, magnesium have been absorbed, after high-temperature firing becomes bamboo charcoal, Duoing 3 times mineral substance than charcoal can be concentrated in the bamboo charcoal, when bamboo charcoal be used for heating up water, cook, make tea, when making coffee, these mineral substance can be dissolved in the water, to replenish the insufficient mineral substance of picked-up in people's daily life.
Two. superpower adsorptive power
The void distribution of bamboo charcoal inside is extremely wide, the inner surface-area of every gram up to 300M square (specific surface area " 300M square/G), the area that is equivalent to a basketball court approximately, be charcoal 3-5 doubly, the minute aperture road of these big small-bores has superpower adsorptive power, can absorb objectionable impuritiess such as muriate, sulfide, formaldehyde, and foul smell, peculiar smell.Place water, fine impurity such as then adsorbable chlorion, tea stain purify water.
Three. the far infrared rays effect
The far infrared rays that is called that a kind of wavelength 1-14HM is arranged in far infrared rays.Because identical with the wavelength of organism self, also be called " breeding first line ", the bamboo carbon of the above high-temperature firing of 700 degree can have far infrared function, and it has thermogenetic effect, can make the health insulation and promote the peripheral blood circulation, has the function of health care.
Four. cover the hertzian wave of harmful to human
The experiment proved that bamboo carbon has the effect of electromagnetic wave shielding, computer, microwave oven, sound equipment, air conditioner are other can to reduce the injury of hertzian wave to human body so bamboo carbon is placed on.
Five. can discharge negative ion
Negative ion can make pallium function and mental activity strengthen, and in high spirits, working efficiency improves, and sleep quality is improved; Negative ion has the effect of obvious vasodilation, can remove the arteries spasm, reaches the purpose that brings high blood pressure down, and negative ion also is of great benefit to for improving heart function and improving myocardial nutrition, and the state of an illness that helps hypertension and cardiovascular and cerebrovascular diseases patient is recovered; Negative ion enters human body by respiratory tract, and it can improve people's vital capacity, and the effect that improves and increase pulmonary function is arranged; In addition, negative aeroion also has effect calm, hypnosis.
Summary of the invention
The present invention adds bamboo charcoal nano level superfine powder in PBT, in order to discharge negative ion and to strengthen other health properties, make a kind of novel healthy material, be applied to articles for daily use, mechanical preparation, can effectively eliminate harmful toxic matter, absorb harm ray, make the work living environment of a health.
