Description

The manufacture method of wear-resistant composite building block supporting plate

Technical field

The present invention relates to a kind of supporting plate that maintenance is used of building, specifically is a kind of manufacture method of wear-resistant composite building block supporting plate.

Background technology

Along with the forbidding gradually of clay brick, building block has obtained developing rapidly as a kind of novel wall material, and this has brought huge market for the building block supporting plate.At present, the used supporting plate of building block is made by timber, bamboo wood, plastics or steel plate usually, but wooden, bamboo matter supporting plate is not wear-resisting, easy to crack, buckling deformation and damage, not wear-resisting, the yielding equally and damage of plastics supporting plate, their life cycle is all short, though and the steel supporting plate is wear-resisting, noise is big, weight is big, cost is high, very easily corrosion.

Chinese patent CN2561716Y discloses a kind of The evil TANG of the gesture of mending Cui a small wooden pile, it has the compound sandwich layer of bamboo matter, be compounded with a bamboo thin slice braid above the compound sandwich layer at this, below this compound sandwich layer, be compounded with a bamboo thin slice braid, the compound sandwich layer of described bamboo matter successively by bamboo silver tile vertical layer, bamboo silver tile horizontally layer, bamboo silver tile vertical layer is compound constitutes.Though this supporting plate is based on bamboo wood, each layer is simple in structure, and be not wear-resisting, not water-fast, only is suitable as the usefulness of producing clay brick, the transportation of porous brick building block base, far can not be applicable to building block supporting plate.

Summary of the invention

The technical issues that need to address of the present invention are, overcome the deficiency of wooden, bamboo matter, plastics and steel supporting plate, provide a kind of have indeformable, do not come unglued, the compound supporting plate of novel bamboo base of characteristics such as abrasion resistance properties height, life cycle are long, for building concrete building block large-scale production provides technical support.

Wear-resistant composite building block supporting plate of the present invention, by top layer and sandwich layer, impregnation, lamination, hot pressing are made on request, it is characterized in that: two top layers are 2~3 Al 2O 3Abrasion-proof paper, liner hardwood veneer, or by the veneer of making after the compressed densification of cork veneer; Described sandwich layer bosom layer be 3~5 layers radially bamboo slight the radial bamboo curtain of braiding, other layer on layer two sides, sandwich layer bosom slightd the tangential bamboo curtain splint of braiding entirely for tangential bamboo, and is one group by per 3 layers, divides 4~8 groups of crisscross laminating.

Described liner compression compact veneer is by cork veneers such as China fir, poplars, and pressurization suppresses forming after soaking the phenol phenolic resin glue under HTHP.

This supporting plate adopts hardwood veneer and densification cork veneer, is because have higher intensity, and is also wear-resisting; Use radial bamboo curtain, then can utilize surf green, tabasheer, improve utilization rate of bamboo.

The manufacture method of wear-resistant composite building block supporting plate of the present invention is characterized in that as follows:

1) bamboo curtain splint impregnation

Radial bamboo curtain, tangential bamboo curtain splint are rolled into volume, put into the impregnation container that fills phenolic resin glue and flood, go out container and place vertically to put and drip glue, wherein the solids content of glue is 22~27%; The phenolic resin glue that uses can be bought from the market, and the solids content of glue is 44~50%, is 22~27% as long as can be diluted to solids content, down together.

2) impregnation bamboo curtain splint drying

Bamboo curtain splint behind the impregnation, 60~85 ℃ of condition dryings, the moisture content of dry back bamboo curtain splint is no more than 15%;

3) selected hardwood veneer, or cork veneer compression compactization

Described cork veneer compression compactization is with the cork veneer, put into boiling water and boil 20~60min, after dripping, place the pressurized treatments jar of the contain phenolic resin glue of sealing, at pressure is that phenolic resin glue 8~15min is soaked in pressurization under 3.5~4.5MPa, after dripping glue, again veneer behind the impregnation is placed hot press, in temperature is that 135~155 ℃, unit pressure are 3.5~4.5MPa condition lower compression, when compression ratio reaches 50% heat-insulation pressure keeping when above, 8~15min, the compression compact veneer is made in release after cooling;

4) veneer gluing

At the two sided coatings phenolic resin glue of hardwood veneer or compression compact veneer, the single spreading amount is 120~150g/m 2, the solids content of glue is 44~50%;

5) lamination

With 3~5 layers of (all-cis line) radial bamboo curtain is the bosom layer of supporting plate; Tangential bamboo curtain splint is one group with 3 layers (all-cis lines), totally 4~8 groups, be stacked in bosom layer upper and lower surface symmetrically by crisscross mode, be inner liner with hardwood veneer or compression compact veneer afterwards, it is stacked in the upper and lower surface of tangential bamboo curtain splint symmetrically, at last with 2~3 Al 2O 3Abrasion-proof paper is stacked in the upper and lower surface of veneer, is combined into the slab of wear-resistant composite building block supporting plate.This step has made full use of the mechanical characteristic of bamboo wood, and that bamboo curtain splint divides is tangential, radially, stacks staggeredly, suppresses mutually, and the internal stress when effectively having offset supporting plate bulking, drying shrinkage has reduced buckling deformation.

6) hot pressing

To go up the step slab and put into hot press, under unit pressure 0.8~1.5Mpa condition,, be heated to 135~155 ℃ afterwards more earlier at 60~70 ℃ of following preheating 5~10min, at unit pressure 3.0~4.5MPa condition lower platen, last segmentation is unloaded and is pressed into wear-resistant composite building block supporting plate.

The inventive method is simple, ripe, can instruct suitability for industrialized production.Prepared building block supporting plate has anti-wear performance good (wear-resisting revolution is not less than 9000 to be changeed, and is no more than 2000 levels of changeing far above wear-resisting revolution wooden, bamboo matter supporting plate), is difficult for buckling deformation and advantages such as damage, life cycle length.
