Abstract
The invention discloses a paper pulp for a paper pulp molding fruit tray product. The paper pulp comprises the following raw materials in percentage by mass: 89-94% of virgin wood sheet pulp or waste paper, 1-3% of alkyl ketene polymer, 5-8% of corn starch and dewatering synergist, wherein the dewatering synergist comprises the following components in percentage by mass: 0.15-0.25% of NaOH, 0.16-0.23% of H2O2 and 0.2-0.48% of borax; and the alkyl ketene polymer is an AKD (Alkyl Ketene Dimer) waterproofing agent. The paper pulp formula for a paper pulp molding fruit tray product ensures the forming performance of the pulp, reduces the wood-pulp mixture ratio, and causes less environment pollution; and the product has good strength, water resistance, breathability and other properties.
Description
Technical field
The present invention relates to a kind of paper pulp, relate in particular to a kind of paper pulp of moulded paper pulp product fruit pallet.
Background technology
Since the paper mould technology that rise the nineties in 20th century, now be tending towards ripe.Along with deepening continuously and sustainable development of economy of China's reform and opening-up, fruit market also presents the development pattern of multiscale and many kinds, and outlet is also than increasing faster.Therefore, corresponding fruit inner packing, under the situation of the pressure of the current market demand and environmental protection sternness, paper pulp molding fruit tray product has had development at full speed.Moulded paper pulp product also can be made as requested various shapes and adapt to packed article to the requirements such as carrying, location and buffering of packing except intensity and toughness with general paper products, can replace the packing of foamed plastics fully.World's environmental consciousness constantly strengthens, and foam plastic product more and more is restricted, and has more and more come into one's own for the paper matrix packing solution of moulding with paper.The paper mould fruit tray is to pack with the fruit that environment-friendly paper pulp is made by three-dimensional paper technology.This fruit pallet not only plays contact-impact and the abrasive buffer protection function of friction in the transportation of fruit and storage process; can also distribute " sultry " and absorb moisture content; suppress " ethylene concentration "; particularly midsummer or torrid areas; because paper-pulp molded pallet does not intercept respiration heat; can absorb evaporation moisture content, prevent that fresh fruit from rotting, play the effect that other packings can't play thereby reach.
Domestic paper pulp molding fruit tray product and have a certain distance abroad.Wherein one of gap is exactly the non-science of paper pulp prescription.The paper pulp prescription of paper pulp molding fruit tray product requires paper pulp homogenate degree height, and the slurry formability is good, goods compressive resistance and impact strength height, waterproof and dampproof, good permeability, easily degrade recyclable.Paper pulp prescription of the prior art is many to be main material with former wood pulp pulpboard or waste paper, is aided with auxiliary agents such as waterproofing agent, bonding agent and dehydration synergist.Auxiliary agent has greatly influenced the formability of moulded paper pulp product.The auxiliary agent of different chemical composition and heterogeneity proportioning has greatly influenced the formability of moulded paper pulp product and the various serviceabilities of finished product.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of paper pulp that is used for the fruit pallet of fruit accumulating is provided.
The raw material of the paper pulp of paper pulp molding fruit tray product comprises log slurry pulpboard or waste paper, alkyl ketene condensate, cornstarch and dehydration synergist, and the synergist that wherein dewaters comprises NaOH, H
2O
2And borax, take the paper pulp prescription of mass percentage content paper pulp molding fruit tray product as: former wood pulp pulpboard or waste paper as 89%～94%, the alkyl ketene condensate as 1%～3%, cornstarch as 5%～8%, NaOH is as 0.15%～0.25%, H
2O
2Be 0.16%～0.23%, borax is 0.2%～0.48%.
Described alkyl ketene condensate is the AKD waterproofing agent.
Paper pulp prescription provided by the invention has been introduced corn starch ingredient compared to traditional paper pulp prescription, made full use of cornstarch and with the characteristic of other additive particular combinations, thereby can obtain the fruit pallet of desired properties.Primary raw material has reduced the wood pulp proportioning thereby the use of cornstarch has not only replaced the former wood pulp pulpboard of part, and then has reduced cost of sizing agent; And cornstarch is as a kind of component NaOH, H that has in good cohesive and filming performance macromolecular compound and the dehydration reinforcing agent
2O
2The advantages such as interacting with borax and AKD waterproofing agent can be used as adhesive in the slurry, and it is good to have a bond properties, cheap, nonpoisonous and tasteless.The paper pulp prescription of paper pulp mold goods fruit pallet provided by the invention has guaranteed the formability of slurry, has reduced the wood pulp proportioning, and environmental pollution is little, and every performances such as product strength, moisture resistance and gas permeability are good.
The specific embodiment
The raw material of the paper pulp of paper pulp molding fruit tray product comprises log slurry pulpboard or waste paper, alkyl ketene condensate, cornstarch and dehydration synergist, and the synergist that wherein dewaters comprises NaOH, H
2O
2And borax, take the paper pulp prescription of mass percentage content paper pulp molding fruit tray product as: former wood pulp pulpboard or waste paper as 89%～94%, the alkyl ketene condensate as 1%～3%, cornstarch as 5%～8%, NaOH is as 0.15%～0.25%, H
2O
2Be 0.16%～0.23%, borax is 0.2%～0.48%.
Described alkyl ketene condensate is the AKD waterproofing agent.
Compared to traditional paper pulp prescription, the present invention has fully used cornstarch and has comprised the characteristic of ADK and dehydration synergist particular combinations with other additives, thereby obtains the fruit pallet of desired properties.
Cornstarch is a kind of recyclability natural polymer, has good cohesiveness and filming performance.Former cornstarch relative molecular mass is bigger, the degree of polymerization is higher, direct applied cohesiveness is very poor, changes solubility and the viscosity that its molecular structure and performance just can be controlled starch but through physics, chemistry or biological method starch is carried out limited modification.NaOH, H have been added among the present invention
2O
2With borax and AKD, and by rationally scientifically proportioning brought into play fully the various physical chemistry biological properties of cornstarch.
Cornstarch is not very high as part raw material sub itself to the ratio requirement of various additives, and and various component interactions form adhesives and have a lot of conditions to satisfy.For binding sizing agent preparation in the slurry, very tight to the requirement of slurry pH value and total alkalinity, pH value and total alkalinity must be controlled at respectively 8.0～8.5 and 50～150mg/kg, so should add alkali compounds NaOH its basicity is met the requirements.AKD is very big as waterproofing agent bonding inner impact in slurry, its content can not be too high also can not be excessively low, its consumption must strictly be controlled.
