Abstract
The invention provides a molded pulp production method. The method comprises the following steps: (1) smashing raw materials, removing sand and grinding to make pulp fibers; (2) mixing a bonding agent, an aid and water into paste in the weight ratio of (10-15):1:(10-15); (3) adding the prepared pulp fibers and paste into a mixer for mixing; (4) cutting the mixture to obtain mixture particles; (5) adding a foaming agent into the mixture particles, and injecting into a die; (6) molding; (7) cooling and demolding. By adopting the method, the strength and buffering performance of a molded pulp product are effectively improved, the conventional production method of a molded pulp material product is changed, the conventional low-efficiency production method is turned into an advanced efficient automatic production method, and the thin-wall solid structure of the product is turned into a foam-molded porous structure. The structural strength and buffering performance are enhanced, the labor intensity is lowered, the operation condition is improved, large-scale automatic production is realized, the production cost is reduced, and the production rate is increased.
Description
Technical field
The present invention relates to paper pulp technical field, relate in particular to a kind of method for paper pulp molding production.
Background technology
China is comparatively weak at hardware (technical method, device) system and software (regulation, standard, the system) system aspects of discarded object recycling regeneration at present.In Chinese MSW research, all kinds of packaging wastes account for 30%～40%, and Plastics Packaging Wastes accounts for 4%～5% (wherein foamed plastic discarded object accounts for again significant proportion), every year with 10% speed sustainable growth.By current China's Mainland Waste Disposal Technology level, one ton of plastic garbage that directly indirectly to process (comprising recovery, landfill, burning, regeneration) comprehensive cost be the former output value is more than 10 times.Therefore " white pollution " phenomenon in environment is still continuing, each big city is faced with increasing environmental management pressure.In China's electronic enterprises, the EPS foamed plastic amount that only these the 2 kinds of packings of product of colour television set and picture tube are used reaches more than 20,000 ton every year, and volume conversion reaches ten thousand stere more than 100.The front national Ministry of Electronics Industry once packed improved emphasis to substitute the plastics such as EPS as " 95 " and Tenth Five-Year Plan Period promoting moulded paper pulp product.But up to the present, the application of paper mould product only accounts for 2%～3% of whole electronic products consumption packaging material.No matter domestic or external, for various reasons, it is slow that paper mould product substitutes the research application progress of the materials such as EPS generally, the requirement of the development of failing to keep pace with the times.
Compared with EPS; because having raw material sources, enriches moulded paper pulp product; cost is low; gas permeability, flexibility, rigidity and intensity are good; can there is certain protective value and shockproof cushioning performance to commodity, can play location, measuring body effect, and there is the feature of ventilation and heat, therefore it is mainly used in the buffer pad packaging of fresh fruit, food, furniture and other products; also can be used for the vessel of non-packaging purposes, as plant flowerpot etc. simultaneously.But, the deadly defect of moulded paper pulp product is now that its structural strength and shock-absorbing capacity are not as good as EPS foamed plastic.Although moulded paper pulp product is for the buffering package of product, but because buffering effect is not good, be only applicable at present egg tray, the liner padded coaming of mobile phone etc., manufacturer is difficult to produce the paper pulp moulded articles of large plane, high depth, thereby cannot meet a large amount of household appliances as the demand of the electronic product packagings such as television set, rear-projection, computer, kinescope.Therefore, just need to improve intensity and the shock-absorbing capacity of paper mould paper product.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, provide a kind of and can effectively improve the intensity of paper mould paper product and the method for paper pulp molding production of shock-absorbing capacity.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: method for paper pulp molding production, comprises step:
1) by raw material pulverizing, desanding, milled processed, make paper pulp fiber;
2) by binding agent, auxiliary agent and water according to the mixing thickener of making in weight ratio 10～15:1:10～15;
3) add batch mixer to carry out batch mixing the paper pulp fiber of above-mentioned preparation and thickener;
4) above-mentioned batch mixing is carried out to blank and obtain batch mixing particle;
5) after adding blowing agent in above-mentioned batch mixing particle, be injected into mould;
6) moulding;
7) cooling and demolding.
As further optimization of the present invention, described binding agent is the mixed solution of starch and synthetic resin, and wherein the weight ratio of starch and synthetic resin is 9:1～2.
As further optimization of the present invention, described auxiliary agent is diethyl phthalate, and the weight ratio of described auxiliary agent and described paper pulp fiber is 1:15～20.
As further optimization of the present invention, described paper pulp fiber and thickener add batch mixer to carry out batch mixing by weight 2:1～3.
As further optimization of the present invention, described blowing agent is sodium carbonate or carbonic hydroammonium; Described blowing agent and described paper pulp fiber weight ratio are 1:10～15.
As further optimization of the present invention, described forming temperature is 100～200 DEG C, time 60～90min.
As further optimization of the present invention, described cooling and demolding chilling temperature is 25～30 DEG C.
Owing to having adopted technique scheme, method for paper pulp molding production, comprises step: 1), by raw material pulverizing, desanding, milled processed, make paper pulp fiber; 2) by binding agent, auxiliary agent and water according to the mixing thickener of making in weight ratio 10～15:1:10～15; 3) add batch mixer to carry out batch mixing the paper pulp fiber of above-mentioned preparation and thickener; 4) above-mentioned batch mixing is carried out to blank and obtain batch mixing particle; 5) after adding blowing agent in above-mentioned batch mixing particle, be injected into mould; 6) moulding; 7) cooling and demolding; Intensity and the shock-absorbing capacity of paper mould paper product are effectively improved, change the production method of traditional paper pulp die material product, make its working system from traditional poor efficiency turn to advanced efficiently automatic working system, change the thin wall-type entity structure of goods into foaming open grain structure.Improve structural strength and shock-absorbing capacity, reduce labor intensity and improve operating condition, form production scaleization and automation, reduce production costs and boost productivity.
