Abstract
The invention discloses a production method of an environmentally-friendly vegetable fiber tableware. The method adopts vegetable fibers as a main material, amino resin with the advantages of good chemical stability, high strength, high glossiness, non-toxicity and harmlessness as a main adhesive and starch and polyvinyl butyral as adhesive aids, so the strength of the tableware is effectively improved, the product performances are improved, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of preparation method of degradable plant fibre environment protecting tableware.
Background technology
Plant fiber tableware kind is a lot of in the market, but wherein has many products not reach sanitary index required by national standard and intensity index.Major cause is that tackiness agent selection is improper, proportioning is improper and processing molding method is improper.Directly by plastics and the simple mixed milling of vegetable fibre, quantity of plastics very little, easily cause tableware in use vegetable fibre divide and parse; And quantity of plastics can make product cost raise at most, make tableware degradation property lose simultaneously.
Summary of the invention
To achieve these goals, the invention provides a kind of preparation method of vegetable fibre environment protecting tableware.Main technical scheme is as follows:
The preparation method of vegetable fibre environment protecting tableware, comprises the steps:
(1) vegetable fibre is cleared up, removing silt and rotten thing;
(2) vegetable fibre after cleaning is pulverized, become 60-80 object fines;
(3) by proportion by weight, the vegetable fibre 250-350 part after above-mentioned pulverizing is added mixing machine, add aminoresin 70-100 part, starch 30-50 part, thermoplastic resin 5-10 part, toning agent 1-5 part, releasing agent 1-5 part simultaneously, mixing 1-2 minute, then mixing 5-10 minute in mixing roll, obtained compound;
(4) compound is put into hot pressing die hot-forming, pressure is 1-15Mpa, temperature 150-200 DEG C, and insulation 1-2 minute, is vented 1-2 time, is made as product in pressure maintaining period;
(5) product is made as finished product through finishing, sterilization, packaging.
As preferential, the vegetable fibre described in step (1) is one in stalk fibre, rice hull cellulose, bagasse fibre or its mixture.
As preferential, step (3) described thermoplastic resin is polyvinyl butyral acetal.
The invention has the beneficial effects as follows: have selected chemical stability good, there is high strength, high glossiness, nontoxic aminoresin as main tackiness agent, coordinate starch and polyvinyl butyral acetal for helping tackiness agent, effectively improve tableware intensity index, enhance product performance and also reduce costs simultaneously.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
Embodiment one: prepare environment-protective cup
(1) stalk fibre is cleared up, removing silt and rotten thing;
