Abstract

The invention provides a kind of novel leather shoes or the heel and the manufacture method thereof of leather boots.The powder that the cane of fiber-like plants such as utilization saw foam, bamboo bits or grass stalk is milled into is primary raw material, adds several additives matter, through stirring, is mixed with the raw material that fibrous composite makes to make heel after the mixing.This fibrous composite is packed in the heel pressing die, with a compression moulding of hot-press method.Heel with this method is made can satisfy the requirement of leather shoes or leather boots production and use, used raw material wide material sources, and manufacture process is easy.Use this method to make heel, can reduce the heel cost, and can save goods and materials such as timber, rubber.

Description

Composite fiber heel

The invention relates to powder shape fiber-like raw material such as saw foam etc. is matrix, add multiple auxiliary material after, with the one-time formed heel of hot-press method, be the novel footwear used about leather shoes, leather boots with and the invention of manufacture method.

Existing leather shoes or leather boots heel are to make with wooden, rubber or leather, middle and highly generally follow with Wooden shoes with leather shoes or leather boots, around the heel japanning or bag with leather, again with the nail nail on sole.In low with leather shoes or leather boots, make heel with rubber mostly, or make type with sole, or with independent Nail for heel on sole, Wooden shoes is followed, and needs by manually wooden blank being whittled into the heel shape, relatively take a lot of work, timber utilization rate is not high yet, and it is by hot-forming that rubber boots are followed.Productivity ratio is higher, but will consume more rubber.

Purpose of the present invention, be that a kind of fibrous composite of making for main former material with the cane powder of saw foam, grass stalk, cotton-wool bar or fiber-like plants such as bamboo bits, willow Teng bar will be provided, heel by a compression moulding, to the requirement of heel, and the cost price was cheaper during this heel can satisfy leather shoes or leather boots production and use.Another object of the present invention provides the manufacture method of above-mentioned heel.

The present invention is done in such a way that saw foam, bamboo bits, or the cane of fiber-like plants such as willow Teng bar, grass stalk, cotton-wool bar is milled into the powder shape.Through after the processing of operations such as screen, cleaning, bleaching, oven dry as matrix material, add magnesia as filler, and add pigment as required, after stirring, mix.To mix by a certain percentage as the epoxy resin of bonding agent and dibutylester or dibutyl ester, and stir as plasticizer.Mixture with epoxy resin and plasticizer is diluted then, stirs simultaneously, the bonding agent after the dilution is added in the mixture of matrix material and filler, fully stirs simultaneously, and above-mentioned every raw material is mixed equably.Add curing agent at last, and stir, curing agent is matched according to epoxy resin, acid anhydride type curing agents such as general available ethylenediamine, diethylenetriamine.

Above-mentioned formula rate can be represented by the formula:

(bonding agent+plasticizer+diluent+curing agent)/(matrix material+filler)=1.5

By above-mentioned operation, prepared compacting heel used fibrous composite, the fibrous composite for preparing is packed in the heel pressing die, heating on hot press, pressurization, promptly plastic.According to the size of hot press and being of different sizes of heel, pressing die can make single, also can make a plurality of compactings simultaneously, and feed way can be a hand charge, also can be mechanization or semi-mechanization mode.

Require control temperature, pressure and hot pressing time during hot pressing.This will be according to the size of compacting workpiece, i.e. the size of heel and thickness, and the quantity of workpiece when once suppressing and determine that temperature is low excessively, the time is too short can make curing insufficient; The too high meeting of temperature makes curing rate too fast, and the material fragility after the hot pressing increases.Hypotony can increase the difficulty of pressing process; Too high pressure then will improve the requirement of strength of pressing die, also is unnecessary.Whole hot pressing is simple, and is easy to operate.

After hot pressing finishes, turn off press, take out pressing die, the in type heel demoulding is promptly obtained product.The heel that makes thus has higher mechanical properties, and more accurate size and dimension also can be followed closely on the sole of leather shoes or leather boots with nail at an easy rate.

Compared with the prior art heel with this fibrous composite is made, can reduce the cost of heel greatly, makes heel with this method, can also save raw material such as timber, rubber.

Claims

1, a kind of heel is characterized in that with the fibrous composite being raw material, uses the hot-press method one-shot forming.

2, the described heel of claim 1, its fibrous composite are the powders that is milled into the cane of sawing fiber-like plants such as foam or bamboo bits or grass stalk, cotton-wool bar, willow Teng bar, or the mixed powder of above-mentioned all raw material is a matrix.

3, claim 1 or 2 described heels, in its fibrous composite, employing magnesia is filler.

4, claim 1 or 2 or 3 described heels adopt epoxy resin as bonding agent in its fibrous composite.

5, the described heel of claim 4 adopts dibutylester, dibutyl ester as plasticizer in its fibrous composite.

6, claim 4 or 5 described heels adopt acid anhydride type curing agent.

7, the described heel of claim 1, in the powder that the cane with fiber-like plants such as saw foams is milled into, add magnesium hydroxide filler and pigment, add epoxy resin adhesive and dibutylester or dibutyl ester plasticizer again, add acid anhydride type curing agent again, and the fiber-like composite that after stirring, obtains, once make the heel manufacture method of heel with hot pressing.
