Abstract
The invention discloses a fiber rapier loom reed and a manufacture method thereof. An A component and a B component are adopted, the weight ratio of the A component to the B component is 1:1, the component A and the component B are mixed through an injection machine mixing head, then the mixture is injected into a reed mould, the mixture has the polymerization reactions and forms in the mould, and the fiber rapier loom reed is obtained. The A component is composed of dicyclopentadiene and a main catalyst, and the B component is composed of dicyclopentadiene and an activator. The double-component reaction injection moulding technology is adopted, thus processing process is largely shortened, processing speed is largely increased and the production cost is reduced. The physical and mechanical properties of the materials can fully satisfy the usage requirement of the reeds, phenomenon of friction pilling and yarn break between the reeds and the fiber yarns no longer exists, and the appearance and quality of the fabrics are guaranteed.

Spend for 2.5Kg/s.
Wherein, dent shaping time in mould is 2～5 minutes.
Present invention also offers a kind of fiber rapier loom dent, it is described in any of the above-described
Manufacture method be obtained.
（Three）Beneficial effect
Fiber rapier loom dent and its manufacture method that technique scheme is provided, adopt
Two-part reaction injection molding technique, highly shortened work flow and speed, reduces system
Cause this, the physical and mechanical properties of material itself can meet the use requirement of dent, solve former
The friction fluffing of dent and fiber wire, fracture of wire phenomenon are it is ensured that the outward appearance weaved cotton cloth and quality.
Specific embodiment
With reference to embodiment, the specific embodiment of the present invention is described in further detail.
Following examples are used for the present invention is described, but are not limited to the scope of the present invention.
The present embodiment dent adopts dicyclopentadiene（DCPD）, by reaction injection molding method
Make.Comprise steps that：
Step 1：A, B two of being mixed to form by DCPD respectively component is mixed by injector
Syncephalon mixes, and is injected into generation polymerisation in mold cavity with reaction injection molding machine；
Step 2：After dent sizing, with core-removing device, core is deviate from from die cavity.
In above-mentioned steps 1, before DCPD component being injected into the die cavity of mould, will
Mould and core are combined into whole mould bases and rise, and tilt 45 degree.Rise frame purpose be in order that
Material regular distribution as far as possible after DCPD mixing material entrance die cavity, and avoid producing gas
Bubble.
In the preparation method of above-mentioned dent, component A is dicyclopentadiene and major catalyst；B group
It is divided into dicyclopentadiene and activator, the weight of described A, B bi-component is than for 1：1.Wherein,
Major catalyst is WCI6/TiCI4Toluene solution containing phenol, rises and improves reaction speed, when reducing reaction
Between effect, activator be Et2AICI/Et2Zn, acts the degree of polymerization improving reaction and heat resistance,
Make reaction more abundant, obtain the cross-linked structure of excellent performance.If not using major catalyst and work
Agent, reaction can not fully be carried out, and cannot get the polymerizate of excellent performance.
In component A, the weight of dicyclopentadiene and major catalyst is than for 1000：1～1000：2；
In component B, the weight ratio of dicyclopentadiene and activator is：1000：0.5～1000：1.
In the step 1 of said method；Injection pressure is 0.4～0.6MPa；Mold cavity temperature
70 DEG C～75 DEG C of degree；Mandrel temperatures are 80 DEG C～90 DEG C；Mould mold clamping force 0.2-0.4MPa；Note
Firing rate degree is 1.8-3.5Kg/s.Preferably, injection pressure is 0.5MPa；Mold cavity temperature
73℃；Mandrel temperatures are 85 DEG C；Mould mold clamping force 0.3MPa；Injection speed is 2.5Kg/s,
Under this process conditions, 120 DEG C of heat distortion temperature can be obtained；Modulus of elasticity in static bending 1800Mpa;
Cantilever beam impact strength 6.72N/m；Tensile strength 450Kgf/cm2；In 10%HCI and
In 40%NaoH solution, weight does not change；And the more excellent product of pore-free.
