Abstract
A jute fibre board in different shapes is made up of skeleton that is felt made of jute fibre or its cloth and phenolic resin or organosilicon modified phenolic resin through such steps as immersing felt in resin with ratio of 1:0.5-1.5 in weight, rolling, baking, solidifying, thermal moulding at 130-140 deg.C or 110-130 deg.C and trimming, and features use of low-grade or waste jute fibre as raw material, no poison and pollution and high properties including thermal and audio insulations and corrosion, fire and impact resistance.
Description
The present invention relates to natural fabric plate and manufacturing technique thereof, particularly Corchorus capsularis fiber board and manufacturing technique thereof.
Present panoramic fiberboard is widely used in building board and vehicle liner plate like asbestos fibre corrugated sheet, glass mat or the like.Because the radioactive pollution of asbestos fiber sheet is progressively replaced by other fiberboard.Recently utilize bamboo and wood, the sheet material of natural fabrics such as grass has all come out, as wound card, hardboard, sawdust-board or the like.But the strength ratio of this class sheet material is lower.Tossa is traditionally as the system gunnysack, but all types of plastic woven bag has replaced gunnysack recently, and the jute mill is in trouble.A large amount of low-grade flax fibres and noil leftover bits and pieces do not find a place where one uses one's talents and cause significant wastage simultaneously.
The objective of the invention is to overcome the problem that prior art exists, abundant sharp ashmara jute fiber and noil leftover bits and pieces development nontoxic pollution-free are heat insulation, sound insulation, and anticorrosion, fire-retardant, lightweight and high-intensity fiberboard and manufacturing technique thereof.
Purpose of the present invention adopts following scheme to realize: phloem fiber was a raw material after the present invention adopted natural jute or bluish dogbane to come unstuck, constitute by flax fibre and phenol glue, it is characterized in that: the numb felt made from burlap and numb fibre is the skeleton of sheet material, impregnated in burlap or the flax fibre with phenol glue or with organic silicon modified phenolic glue, the weight ratio of glue and numb felt is 0.5～1.5: 1, makes sheet material through hot forming.
The manufacturing technique of Corchorus capsularis fiber board of the present invention is: phloem fiber is that raw material is made into burlap and flax fibre by traditional handicraft after coming unstuck with jute or bluish dogbane, be reprocessed into numb felt, it is characterized in that, the fiber crops felt is through the saturated dipping of impregnating agent, and the roll mangle is dried, again through cutting, heat is touched and is pressed into shape, and solidification temperature is 130～140 ℃ or 110～130 ℃, and product is made in finishing.
Impregnating agent of the present invention is base catalysis phenolic resin glue or organic silicon modified phenolic resin glue and fire retardant.Wherein the preparation method of base catalyst resin glue is: formaldehyde and phenol mol ratio are 1: 1～2.15, base catalyst: NaOH, potassium hydroxide, barium hydroxide, ammoniacal liquor, ph value of reaction is between 7.2～11.5,70～95 ℃ of reactions 2～4 hours,, or be cooled to 60 ℃ of vacuum dehydrations then 102～105 ℃ of dehydrations, with the methenamine be crosslinking agent to make solidification temperature be 130～140 ℃ phenolic resins, the impregnating agent of special-purpose tossa goods punching block compacting.If add 1.5～3% polyamines functional group organo-silicon coupling agent: X at the above-mentioned phenolic aldehyde that makes

Distinguishing feature of the present invention is: adopt natural tossa to comply with the world trends that go back to nature.This product nontoxic pollution-free collects heat insulation, sound insulation, anticorrosion, fire-retardant and not only light weight but also intensity high impact-resistant etc. were multi-functional in the moral character of one, have the characteristic of plectane stretching again, hot pressing becomes the plane, camber, corrugation shape and complicated concavo-convex heterotype profiled sheet of multi-line and goods.Thereby can utilize rudimentary fiber crops or noil to reduce cost.Surface plate can be widely used in building board, interior decoration sheet material and compartment sheet material, and corrugated sheet can replace the glass plate, asbestos board and making roof, Ku Ding, various wayside pavilion, tea-booth, booth etc. " colored corrugation top board " (being called " colored heat wave plate " abroad); Sketch plate can be used for car, dolly car liner and various interior lining panel or special-shaped engineering accessories etc.Technological process of the present invention is simple, and technological parameter is controlled easily.
Further specify the present invention below in conjunction with embodiment:
Embodiment 1
Present embodiment is a kind of car door lining product and method for making thereof:
Getting a foothold with the noil of inferior grade (the third-class and fourth class) flax fibre and each operation is 475 kilograms of raw materials, through opener to the lapping machine to putting platform, put platform and make the numb felt that accompanies flax fibre in the middle of two layers of burlap through just rolling needing machine to the second again to rolling needing machine, 1.3 kilograms of every materials, with this fiber crops felt is skeleton, through the saturated dipping of impregnator, with glue: 0.5: 1 ratio of numb felt weight ratio adds impregnating agent.The lab scale method for making of impregnating agent organic silicon modified phenolic resin glue is: 94 gram phenol add in the reaction bulb, formalin 112 grams of adding 37%, add barium hydroxide 0.3 gram, be heated to 90 ℃, 90～95 ℃ of reactions 2 hours, the dehydration of cooling final vacuum added methenamine 7.2 grams to transparent, add organo-silicon coupling agent 2 gram again, add calcium sulfate 20 and restrain to such an extent that solidification temperature is 110～130 ℃ a impregnating agent.Add 650 kilograms in organic silicon modified phenolic glue in the present embodiment.The roll mangle is degree through the continuous conveying-type drying machine drying of flat Net to moisture content 8～10% again, and in blocks through cutting again, 120 ℃ of hot-dies add 8 tons of pressure press formings, and 1000 of products are made in finishing.The product design that makes is accurately clear, and concavo-convex radian moulding is accurate, and the demoulding is good.
