Abstract
The environment friendly tableware of degradable plant fiber is produced with the materials including plant fiber 250-350 weight portions, amino resin 70-100 weight portions, oxidized starch 30-50 weight portions, polyvinyl butyral 5-10 weight portions, toner 1-5 weight portions, and demolding agent 1-5 weight portions. The production process includes the steps of mixing at 50-100 deg.c for 5-10 min, and hot pressing to for at 10-15 MPa and 150- 200 deg.c for 30-100 sec and exhausting gas for three times. The environment friendly tableware of degradable plant fiber has high chemical stability, high strength, good degrading performance, and no toxicity and harmful material.
Description
Technical field
The present invention relates to a kind of production method of green tableware of degradable plant fiber.
Background technology
It is main production raw material that plant fiber tableware is meant with the vegetable fibre, is equipped with a dishware of various tackiness agent and subsidiary material machine-shaping.Most of this dishware is that main raw material is (as bagasse with the straw-stalk type cultural waste material, rice husk, the cassava stalk, wheat straw stalk etc.), not only reduced the atmospheric pollution that burning straw causes, improve the added value of stalk class, and met the principle of cycle saving economy, do not caused new environmental pollution after the use.So plant fiber tableware is the Novel tableware that a kind of feature of environmental protection is strong, be worth promoting.
The main difference of the standard of plant fiber tableware classification according to selected tackiness agent; The main tackiness agent that uses has synthetic adhesive (as plastics, resin), natural adhesive (as starch, Mierocrystalline cellulose) and inorganic adhesive several big classes such as (as gypsum).The tableware product is very high to the requirement of making material, and very strong chemical stability and suitable intensity be arranged, and is healthy to guarantee easy to use and user's simultaneously.The plant fiber tableware kind is a lot of in the market, but many products can not be up to state standards fully desired sanitary index and intensity index are wherein arranged.The reason that causes this situation mainly is that the tackiness agent selection is improper, proportioning is improper and processing molding method is improper.For example, some tableware manufacturers is only with plastics and the simple mixed milling of vegetable fibre, quantity of plastics very little, cause easily tableware in use the vegetable fibre branch parse; And quantity of plastics can make product cost raise at most and the forfeiture of product degradation property.
Summary of the invention
The technical problem to be solved in the present invention provides the preparation method of the plant fiber tableware that a kind of chemical stability is good, the degradable performance is good, intensity is high.
The present invention solves the problems of the technologies described above with following technical scheme:
The raw-material proportion by weight of tableware is
Vegetable fibre 250～350, aminoresin 70～100, Sumstar 190 30～50, polyvinyl butyral acetal 5～10, toning agent 1～5, releasing agent 1～5
Tableware is hot-forming, at pressure is under 10～15Mpa condition, temperature is incubated 30s to 100s between 150-200 ℃, and exhaust is 1 to 3 time in pressure maintaining period.
Plant fiber tableware with the inventive method preparation has good chemical stability, the intensity height, and degradation property is good, and cost is reasonable, and is nontoxic, meets national standard (GB18006.1-1999) and plant fiber tableware degraded standard fully.
Embodiment
Plant fiber tableware production method of the present invention, selected chemical stability good, have high strength and high glossiness and nontoxic aminoresin as main tackiness agent, enhancing, increment and moulding booster action, the modified starch that can effectively reduce cost and enhance product performance to be arranged and as toughner and internal plasticizer, effectively improve the polyvinyl butyral acetal of tableware intensity index for helping tackiness agent.
If aminoresin is carried out modification, the solid content and the degree of crosslinking of control aminoresin also can further promote the tackiness agent performance, only need the adhesive components of ratio seldom can satisfy the requirement of sanitary tableware index.
On the starting material working method, adopted and mediated mixing technology, utilize powerful squeeze of gear and shearing force, finish tackiness agent and mix with the degree of depth of vegetable fibre, make them form one.Experimental results show that: raw material is through mediating the tableware of mixing production, can be effectively tackiness agent be transformed into external phase mutually with division between the vegetable fibre, than the tableware of raw material without the mixing production of kneading, the product homogeneity is much higher, the former can meet national standard fully, latter's sanitary index severe overweight.The kneading mixing time is 1min to 5min, and the starting material after mixing can send moulding place moulding.
Plant fiber tableware production method of the present invention, the raw-material proportion by weight of tableware is:
Vegetable fibre 250～350, aminoresin 70～100, Sumstar 190 30～50, polyvinyl butyral acetal 5～10, toning agent 1～5, releasing agent 1～5
The tableware molding mode adopts hydropress hot-forming, at pressure is under 10～15Mpa condition, temperature is incubated 30s to 100s between 150-200 ℃, and exhaust is 1 to 3 time in pressure maintaining period.
Starting material were mediated mixing 5-10 minute under 50-100 ℃ condition before hot-forming.
Embodiment 1: the preparation cup
Raw material is 250 kilograms in bagasse powder, 75 kilograms in aminoresin, 40 kilograms of Sumstar 190s, 10 kilograms of polyvinyl butyral acetals, 3 kilograms of toning agents, 3 kilograms of releasing agents; Above-mentioned starting material were mixed in blender 1～2 minute, then heat refining 5 minutes (50 ℃) in mixing roll.The measuring raw materials that heat refining is good, it is hot-forming to put into hot pressing die, and hot pressing temperature is 150 ℃, and pressure is 10Mpa, press time 30s, exhaust 2 times.The cup tool purged and packed that suppresses gets finished product.
Embodiment 2: the preparation bowl
Raw material is 320 kilograms of powdered rice hulls, 85 kilograms in aminoresin, 35 kilograms of Sumstar 190s, 5 kilograms of polyvinyl butyral acetals, 1.5 kilograms of toning agents, 2 kilograms of releasing agents, above-mentioned starting material were mixed in blender 1～2 minute, then heat refining 8 minutes (80 ℃) in mixing roll.The measuring raw materials that heat refining is good, it is hot-forming to put into hot pressing die, and hot pressing temperature is 170 ℃, and pressure is 13Mpa, press time 50s, exhaust 3 times.The bowl tool purged and packed that suppresses gets finished product.
Embodiment 3: the preparation lunch box
Raw material is 350 kilograms in wheat straw powder, 100 kilograms in aminoresin, 50 kilograms of Sumstar 190s, 8 kilograms of polyvinyl butyral acetals, 5 kilograms of toning agents, 2 kilograms of releasing agents, above-mentioned starting material were mixed in blender 2 minutes, then heat refining 10 minutes (100 ℃) in mixing roll.The measuring raw materials that heat refining is good, it is hot-forming to put into hot pressing die, and hot pressing temperature is 200 ℃, and pressure is 15Mpa, press time 60s, exhaust 3 times.The lunch box tool purged and packed that suppresses gets finished product.
