Abstract

A foam plastic sandwiched with rib net structure is characterized in that at least one layer of rib net is arranged in the foam plastic to lead the mechanical property of the foam plastic to change and the pull as well as the cutting power endured by the foam plastic is completely shared by the rib net. As long as the indexes of material, density and quantity of layer of the rib net, the requirement of bearing various intensities can be meet. The utility model has a broad application and can meet the needs of the fields like construction, packing, transportation, refrigeration, furniture, agriculture and medicine, etc., thereby the mechanical properties of plastic like light quality, heat and sound insulation, rich elasticity can be further played.

Description

A kind of foamed plastics that accompanies the muscle web frame

Technical field

The utility model relates to a kind of foamed plastics, particularly with a kind of associativity muscle net its mechanical property is carried out improved foamed plastics.

Background technology

The conventional foam plastics have kinds such as polyurethane, poly-third ethene, crosslinked polyethylene, crosslinked polypropylene, polyvinylcarbazole, polyimides in the prior art, wherein use polyurethane foamed plastic the most generally.Polyurethane foamed plastic extensively has been applied in fields such as shockproof, packing, cushion material, light building materials with its light weight, thermal insulation, sound insulation, performance such as full of elasticity, but mechanical properties such as, tension anti-shearing because of it are relatively poor, the stressed back of rigid foam frangibility particularly, flex foam cannot stand brute force and pulls, be difficult for and factors such as other object connects, make its range of application be subjected to limitation.

The utility model content

Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of mechanical property that bubble is moulded of improving is provided, and strengthens its tension, the foamed plastics of the interior rib screen structure of anti-shear ability.

The utility model has adopted following technical proposal to solve its technical problem: a kind of foamed plastics that accompanies the muscle web frame is characterized in that: be equipped with one deck muscle net in the foamed plastics at least.The utility model be adopt that metal wire rod tangles, metal sheet punching out or strong fiber are knitted into the well shape, Mi Gezhuan, two Mi Gezhuan, network structure such as cellular.Before foam plastic foaming, earlier the muscle web frame is placed the foaming groove, it is merged in foamed plastics in the foam plastic foaming process well.

Because folder muscle foamed plastics has incorporated the muscle web frame, basic change has taken place in its mechanical property, the pulling force that is born, shearing force are shared by the muscle net fully, as long as indexs such as the material of adjustment muscle net, density, the number of plies just can satisfy the requirement of the various intensity of carrying.

With the roof insulation sheet is example, produce thermal insulation board with the utility model, only need two ends to be fixed on the support on roof, middle without supporting, can be not crooked yet, be able to take blowing hard of storm speed, satisfied the building requirements of roof attachment steadiness fully, the characteristic of the lightweight of foamed plastics, thermal insulation, sound insulation is fully played simultaneously.Simultaneously owing to the chemical stability of foamed plastics, be difficult for advantage such as oxidation, all can reach 10～15 years service life.As carrying out integral assembling with the newly formed large stretch of foamed plastics of this practicality, reduction of erection time and operating expenses greatly in construction.

Fig. 3 is the another kind of structural representation of the utility model muscle net;

Fig. 4 is another structural representation of the utility model muscle net.

The specific embodiment

Come the utility model is further described below in conjunction with accompanying drawing and embodiment.

With reference to accompanying drawing, the utility model is to be equipped with one deck muscle net 2 in foamed plastics 1 at least.This effective reinforcement net 2 can be well shape, Mi Gezhuan, two Mi Gezhuan, network structure such as cellular, can tangle with metal wire rod, metal sheet punching out or strong fiber woollen yarn knitting form.Foamed plastics 1 described in the utility model can be polyurethane, poly-third ethene, crosslinked polyethylene, crosslinked polypropylene, polyvinylcarbazole, polyimides.

In order to guarantee effective fusion of foamed plastics 1 and muscle net 2, muscle net 2 can have a mind to adhere to some and drag wadding or drag silk in the process of tangling, increase the adhesive force of muscle net 2 and foamed plastics 1 with this, foam recipe also will be done suitably to adjust with material according to the muscle net, adjust the flowability of foaming base-material, change expansion rate.

The used muscle net 2 of the utility model can be to use individual layer, also can be multilayer.The material of muscle net 2, specification, density, combined shaped are all selected on demand, reserve connecting elements according to installation requirement when the muscle net makes up simultaneously, can solve the connectivity problem of foamed plastics integral body and other object so well.

Embodiment 1, the roof thermal insulation board: specification is 500 * 50 * 5cm, the iron wire of available φ 0.1～0.2cm tangles into trave or the rice graticule mesh of 3～4cm, with 3 of φ 6cm reinforcing bars, in grid, form individual layer muscle net every the 20cm distributed combination, be combined into the double layer grid structure with two such muscle nets interval 2～3cm again, so just, can produce a kind of roof with pressing from both sides the muscle thermal insulation board, this thermal insulation board can be realized the span of 500cm, in " flat-changed-into-sloping " roofing improvement project, only need two ends to be fixed on the support, just can satisfy the requirement of firm construction standards such as firm.

Embodiment 2, television set Shockproof packaging Turnover Box: with 0.5～0.8 thick aluminium flake punching out boxwork, according to television set set of specifications polymer fabric lattice structure, the carrying handle is reserved in both sides simultaneously, place the cabinet mould, incorporate during foam plastic foaming in the casing, such cabinet can shockproofly can become firm external packing again.

Embodiment 3, the food heat-insulation Turnover Box: the foam plastic reservoir that aquatic products, fruit etc. need insulation to flow and transport, when foam production, add the strong fiber net, and reserve the carrying handle simultaneously, just can make casing firmer, carry more convenient.

Embodiment 4, the foamed plastics tent: form the less net sheet of reticular density with strong fiber, make the slim folder net of light weight plastic foam sheet material, be connected into tent with this kind sheet material again, this tent light weight is easily folding, and can solve thermal insulation, sound insulation well.

The utility model has wide range of applications, and can satisfy the needs in fields such as building, packing, transportation, refrigeration, furniture, agricultural, medical science.Its light weight, thermal insulation, sound insulation, physical characteristic such as full of elasticity are further brought into play.
