Abstract
The invention belongs to the technical field of pulp preparation, and relates to a preparing method for a molded pulp composite product. The preparing method is characterized by comprising the following steps that a die meeting the product specification is manufactured; raw materials are crushed into thick pulp through a hydraulic pulp crusher, and a qualified sizing agent is diluted into the sizing agent meeting the product requirement; the sizing agent is adsorbed and formed through the die and the vacuum adsorption function; a formed wet blank is dried in hot air formed under the heat source function; a heating plate is heated, and the pulp product is pressed under the high temperature and high pressure; a shaped inner support and a shaped outer support are combined; the bonded inner support and outer support are pressed and formed on the composite die; residual materials on the periphery of the product are cut off. The produced molded pulp composite product has good buffering and anti-shaking performance through the corresponding temperature and pressure in the preparing process, the outer surface of the product is smooth and attractive, the friction to a packaged object is effectively reduced, and extremely high application and popularization value is achieved.

The preparation method of a kind of paper mould joint product of the present invention, by adjusting processing sequence in preparation flow, and make the having of paper mould joint product of producing can cushion anti-seismic performance preferably in conjunction with relevant temperature and pressure, and the outer surface of product is bright and clean attractive in appearance, effectively reduce the coefficient of friction to packaging object, the preparation method of paper mould joint product of the present invention has great application value.
Detailed description of the invention
A preparation method for paper mould joint product, is characterized in that comprising the steps:
(1) mould meeting product specification is made;
(2) by hydrabrusher, raw material size degradation is become thickened pulp with raw material, again by after vibrating screen screening paper pulp, accepted stock is diluted to the slurry meeting goods demand, according to client to product particular/special requirement, also appropriate auxiliary agent be can add, waterproof, anti-wet goods function played;
(3) by mould and vacuum suction effect by slurry adsorption forming, the life respectively of Neto and outer bracket, shaping technique priority control three parameters, namely concentration, suction time, dewatering time is starched, slurry concentration and suction time determine thickness and the grammes per square metre of paper holder, it will be determined according to customer requirement, once determine to change easily;
(4) dry in the hot-air (180 DEG C-220 DEG C) wet embryo out after shaping formed under Source, utilize blower fan to extract the moisture evaporated out, reach quick-drying effect;
(5) heat heating board, make paper pulp product mold have higher temperature (170 DEG C-230 DEG C), utilize air pressure or hydraulic pressure (20 tons), under high temperature, high pressure, suppress pulp goods, reach fixed effect, product surface is coarse after drying, and distortion is large; After needing again to use steam humidification, then suppress through high temperature and high pressure with shaping mould, make its profile neat appearance, reach better toughness, there is better shockproof properties.The hot pressing sizing die made is that the product surface making it suppress is smooth bright and clean, should adopt punching block;
(6) Neto after shaping and outer bracket are combined with each other, before compound by matsurface inwards, light is towards outward, and the inside is coated with white glue with vinyl makes interior outer bracket stick together;
(7) the interior outer bracket that will stick together is pressurizeed sizing on composite die, and interior outer bracket is firmly sticked together;
(8) trimming cutter is utilized to be cut away by product periphery excess stock.
The preparation method of a kind of paper mould joint product of the present invention, the raw material described in step (2) comprise log pulpboard, litter decoration, old newsprint.Mould described in step (1) comprises formation mould, shaping mould and composite die, formation mould: material is cast aluminium, and with the drill bit of diameter 2.7mm, pitch of holes is that 10mm × 10mm evenly arranges, and midge mould inflates hole.Bag net 40 order plain weave nets, solder joint seam crossing is little as far as possible, and the patrix cnc of midge mould processes, and give up manually recording of past, shaped article reaches higher quality.For ensureing that hot pressing product does not have the phenomenon such as drawing crack, fold below, rule of thumb the shrinkage ratio of mould must be accurate, higher than mill run accuracy requirement.Shaping mould: material is steel, gives up aluminium in the past, and because the hardness of steel is higher, die life first mate improves, and product quality is more stable simultaneously.Die clearance more about than the gap shrinks of mill run 60%, product appearance is improved.Composite die: material is steel, because two pieces product is combined with each other by needs, so just a set of composite die more than one side mill run.For ensureing after product pressing that two pieces product center site error is at ± 1mm, special by the locating dowel of additional for upper/lower die surrounding diameter 26mm, play guide effect.Thermal source described in step (4) comprises combustion gas, steam and conduction oil.The temperature of the composite setting mould described in step (7) is 140 DEG C-170 DEG C, and pressure is 20 tons.The material that cutter described in step (8) adopts is 6656G or high-speed steel, and shaving die is mounted on the accurate material cutting machine of a kind of four columns, is cut away by product periphery excess stock.
