Abstract

The utility model relates to a fluorescent antistatic protecting hood for a car and a machine tool, and the utility model belongs to a protecting hood for a car and a machine tool when the car and the machine tool are not used. A knitting cloth made from high density polyethylene or high density polypropylene is adopted as the base material of the utility model, the inner layer and the outer layer of the knitting cloth are covered and coated with polyethylene films provided with antistatic agents and fluorescent agents so as to produce to the utility model, the lower end of the utility model is provided with inclined draw strings, and agraffes are used for buckling the knitting cloth with the inclined draw strings to form the utility model. The utility model which is easy to fold has the advantages of simple structure, convenient use, light weight and low cost; besides, the volume of the utility model is small, and the utility model is easy to store; the functions of rainproof, snow-proof, dustproof and antistatic of the car can be realized, and the car can emit fluorescence at night; thus, when the car is parked on a road, traffic accidents can be reduced.

Description

Fluorescent anti-static protecting hood for car and machine tool

A kind of car and machine equipment fluorescence, antistatic protection cover, belong to vehicle and the machine equipment sheath of time spent not.

Existing car protective case adopts materials such as one or more layers canvas, soft fabric or nonwoven fabrics to make; its fixing means adopts the cover body bottom that groups such as belt loop, rope, nylon tape are set more and pricks; cover body material therefor quality, particularly behind rain or snow, make moist just heavier; use very effort; and group's bundle is very inconvenient, even stay cord belt loop string is tied at the bottom of will arriving car.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art, a kind of simple in structure, in light weight, rain and snow, dustproof, electrostatic prevention is provided and can sends fluorescence to reduce or to stop to stop on the highway and cause the automobile-used protective case handsome in appearance or the machine equipment sheath of traffic accident at night.

The utility model is realized with following technical scheme: it is by on cover body and the cover body being that thing is formed; said protective case cover body is by being base-material with high density poly propylene or woven polyethylene cloth; the internal layer of this base-material covers the polyethylene foil that scribbles antistatic additive, and the skin of base-material covers and is coated with the polyethylene foil composition that contains fluorescer and pigment masterbatch.It is thing that protective case cover body lower end four angle equal edges are provided with what be made up of oblique drawstring and velcro.

The beneficial effect that the utility model had: 1, because employing is a base-material with the high density knitting, its ectonexine covers respectively and is coated with the polyethylene foil that contains anti-quiet dose and fluorescer and pigment masterbatch, it have in light weight, can be rainproof, snow defence, do not make moist, prevent dust, have fluorescence, antistatic properties, cost is low, easy to use, has positive social benefit.2, make simply, be convenient to batch manufacturing.3, this protective case can solve the outdoor storage problem of vehicle, and the grey problem that falls that solution motor plant, vehicle transaction market park cars for a long time solves the protection problem of sealing vehicle up for safekeeping, has also solved the safety problem that stop night on the highway.4, this protective case is easy to use, has alleviated driver's work capacity greatly, because the moulding color is attractive in appearance, it can become the sign that vehicle uses civilization and safety.

Describe the utility model in detail below in conjunction with drawings and Examples.

Fig. 1 is a car protective case scheme drawing;

Fig. 2 is that car protective case A-A is to cross sectional view.

This accompanying drawing has provided the structural representation of a kind of most preferred embodiment of the utility model car protective case.It is by on protective case cover body and its being that thing is formed.The protective case cover body is intensity, the flexibility that keeps fabricbase by being base-material with polypropylene woven cloth 6, and woven cloth 6 density can be 14 * 14, and promptly every square cun of warp, parallel are each 14, covers respectively on the two sides of woven cloth 6 to be coated with polyethylene foil 5 and 7.For reaching performances such as rainproof, snow defence, overlay film layer thickness single face is 20～25 microns; For dustproof and electrostatic prevention, in internal layer membrane 7, add antistatic additive, to reach the effect of dustproof and electrostatic prevention.Plastic product all has the excellent electric insulation performance, this is because its strand is made of covalent bond mostly, can not ionization also be difficult to transmit free electron, therefore in case in friction process because of electron exchange is difficult to disappear by conduction after charged, the reason of Here it is plastic product static electrification.And plastic product is because easy static electrification; so the dust suction phenomenon of bringing because of static is serious; one deck dust that made car protective case adsorption; influence the outward appearance of outer cover; and because electrostatic interference; at housing with get the friction that when cover produce and form bunch discharge, even produce spark discharge, this phenomenon as we wear that the chemical fibre underwear sends when undressing fizz and the dying fire flower.Therefore, protective case must have antistatic behaviour, can prevent dust and electrostatic prevention.Adopt powdery composite antistatic agent HZ-1 type, these product are by N, N-dihydroxy ethyl stearyl

Primary amine C ₁₈H ₃₇-N

Mix higher alcohol C _16～18

Alcohol, silicon dioxide SiO ₂Cooperate (development of Hangzhou chemical institute) in 0.5～1% the ratio adding poly-vinyl resin in the 45:45:10 ratio, have antistatic, anti-dust suction performance behind the overlay film, and have advantages such as melting welding jail, raising printing fastness, trade mark difficult drop-off, antifade.Outside in the coating film 5; the color masterbatch that adds fluorescer and 0.6～1% makes protection be covered with shades of colours such as white, yellow, orange, silver grey, and can send fluorescence in the dark; make car night on highway during et out of order on the cover protective case can make security identification, prevent the safety traffic accident.When manufacturing, by the blanking of car shape become last slice 1, left sheet 2, right sheet 3, on the mold that the electric heating lines are housed respectively with the method for heat fusion with last slice 1, left sheet 2 and last slice 1, the fusion of right sheet 3 both sides, with roller roll extrusion heat seal.Be provided with coefficient 4 in the cover body lower end, it is four of heat seal oblique bands on left sheet 2, right sheet 3 respectively, and sews on velcro at the other end, also sews on velcro on four relevant positions of last 1.Like this, protective case need not be helped to prick onboard, and also without stay cord button, at the bottom of drill carriage, one takes promptly and closes, convenient and reliable.Only 1.2～1.4 kilograms of the protective cases made from said method and material are very light.Do not add the guard shield that fluorescence also can be made into various machine equipments with this material outer layer, shield sealing equipment up for safekeeping.

Claims

1, a kind of car and machine equipment fluorescence, antistatic protection cover; what comprise protective case cover body and last setting thereof is thing; it is characterized in that the protective case cover body by being that base-material, its inside face cover and be coated with polyethylene foil, its outside face of containing antistatic additive and cover and be coated with the polyethylene foil that contains fluorescer, pigment masterbatch and form with high density poly propylene or woven polyethylene cloth, at the bottom of the cover body four jiaos to be provided with what be made of oblique drawstring and velcro be thing.
