Abstract

An environmentally friendly coffin is made of agricultural straw or stalk (70-94 wt.%), adhesive, e.g. urea-formaldehyde resin or phenolic resin, (5-28 wt.%), and additives, e.g. solidifying agent, setting retarder and viscosity increaser, (0.01-0.5 wt%). Its advantages are no need of wood, and no environmental pollution.

Description

A kind of is the coffin without environment pollution of raw material with the crop stalk

The present invention relates to a kind of funeral and interment articles for use, particularly a kind of is the coffin without environment pollution of raw material with the crop stalk.

At present, the employed coffin of tradition burial in the ground, generally all be to make of high-quality timber, and manufacture method also is individual craftsman with ancient instrument, manual labour processes log scale, its inefficiency well imagines, be exactly the coffin shop be individual workship only, do not have a tame modernized woodworking mill to make coffin efficiently at present yet.China is a populous nation, average every day dead 22000 people, dead every year on average 8030000 people.Law is clearly stipulated in China, and the area that can bury in the ground is generally rural area and remote mountain areas.That is to say that the actual burial in the ground rate of China accounts for 60%, have every year 481.8 ten thousand people to need burial in the ground, and every mouthful of coffin is with 0.4 cubic metre of timber, then the annual need of China be done coffin with 192.72 ten thousand stere high-quality timber.This is one makes us startling numeral, needs every year felling fall a large amount of forests like this, very serious to the destruction of environmental conservation.The China's Forest Resources poorness, but non-wood plant raw material, particularly agricultural wastes (straw stalk) resource is but extremely abundant, crop stalk output is annual to surpass 400,000,000 tons, and cheap, and utilization rate is very low.Reasonably handling effective utilization of forest conservation, environmental conservation and crop stalk well, has been the problem that presses for solution in the present stage social development.On the other hand, along with the raising of people's living standard, vast farmers is more and more little to the demand and the dependence of crop stalk, and crop stalk phenomenon ubiquity is directly burned in wheat harvest or autumn harvest later in the farmland.To such an extent as to usually have influence on the landing of aircraft, people's such as have a good transport and communication network modernization life, make a big impact to environmental protection.

The purpose of this invention is to provide a kind of is the coffin without environment pollution of raw material with the crop stalk, fully overcomes the serious drawback of a large amount of high-quality timber of conventional art consumption, and the rational and efficient use crop stalk reduces the peasant and crop stalk burned the environmental pollution that is caused.

The main composition and the percentage by weight of 6 blocks of sheet materials of coffin without environment pollution of the present invention are respectively: crop stalk 70-94%, adhesive 5-28%, adjuvant 0.01-0.5%.Crop stalk mainly is: straw, corn stalk, kaoliang stalk, Caulis et Folium Oryzae etc.Its main processing technology: at first be with crops cut off, pulverize, dry, glue mixing and add adjuvant, the mould that measures, mats formation, pre-molding, hot-forming.Next is 6 blocks of plates that pressure is touched molding by gluing connection or gluingly adds that bolt connects or the gluing iron nail that adds connects, promptly is assembled into coffin without environment pollution of the present invention.The adhesive that is adopted in glue mixing technology is mainly Lauxite, phenolic resins etc., and adjuvant mainly is firming agent (as ammonium chloride), retarder (as ammonia, carbamide), viscosifier (as polyvinyl alcohol).The mould that is adopted in technologies such as the mould of mating formation mainly is six moulds that the different plates shape is made in advance according to coffin, glue mixing and the straw stalk particle mixture that adds adjuvant are poured in the different moulds, and 6 different needed material quantities of plate are different, need the metering back rationally to inject mould.Before the present invention uses, also can spread fermented bacterium at the coffin without environment pollution inner surface, early merge in order to buried underground coffin with soil.

Advantage of the present invention and good effect: aspect environmental protection, can significantly reduce the peasant and burn the atmospheric pollution that crop stalk causes, save a large amount of high-quality timber; Aspect the comprehensive utilization of crop stalk, turn waste into wealth.The surface spreads fermented bacterium if need within it before coffin without environment pollution of the present invention uses, and buried subterranean coffin will combine together with soil earlier, helps soil optimization.

Claims
